Asparagus Plumosus Plumosa Fern

Hyper-realistic indoor scene of Asparagus setaceus with feathery cladodes, one vine freshly pruned, …

Asparagus plumosus, often sold under the charmingly misleading name Plumosa Fern, is a cloud of green pretending to be something it is not. It looks like a fern that went through a soft-focus filter, but botanically it is a climbing perennial with fine, feathery cladodes that only resemble fern fronds from a distance.

Those soft-looking sprays are actually modified stems doing the job of leaves, which matters because they behave differently when it comes to light, water, and stress.

This plant prefers bright indirect light, meaning a room that feels well lit without the sun blasting directly onto the foliage.

Soil should stay slightly moist while still letting air reach the roots, which means soggy compost is a fast way to turn elegance into mush.

Asparagus plumosus also contains steroidal saponins, defensive compounds common in the asparagus family.

In real life terms, that means nibbling pets or curious humans may experience stomach upset, and rough handling can irritate skin, but it is not a houseplant supervillain.

Treated with basic respect and a little spatial awareness, it is a graceful, slightly dramatic plant that rewards restraint and punishes overconfidence.

INTRODUCTION & IDENTITY

A cloud of green pretending to be a fern is the most honest way to describe the Plumosa Fern, because the entire sales pitch relies on the assumption that nobody looks too closely. The name suggests something ancient and spore-filled, but the reality is far more modern and a little sneaky.

The accepted botanical name is Asparagus setaceus, and that one word, Asparagus, already tells the real story. This plant lives in the Asparagaceae family, the same extended clan that includes edible asparagus and several ornamental species that also enjoy confusing people.

The fern label stuck because the plant has soft, arching sprays that look like fern fronds from across a room, and houseplant marketing has never let accuracy interfere with a good vibe.

Asparagus setaceus is not a fern by any botanical standard.

True ferns reproduce by spores, unfurl new growth as tight fiddleheads, and carry their photosynthetic tissue on actual leaves called fronds. This plant does none of that. Instead, it is a climbing, vining perennial that produces wiry stems capable of scrambling through nearby supports if given half a chance.

The delicate green “leaves” are actually cladodes, which are modified stems flattened and branched to take over the role of leaves. This matters because cladodes are tougher than they look and respond differently to stress.

When conditions are wrong, they yellow, crisp, or drop in ways that confuse people expecting fern behavior.

Photosynthesis in Asparagus setaceus happens in these cladodes, meaning the plant captures light energy in its stems rather than traditional leaves. The true leaves exist only briefly and then shrink into tiny scales along the stem, which most people never notice. This adaptation reduces water loss in its native environments and allows the plant to balance light capture with survival during dry periods.

The energy produced by photosynthesis is stored in a tuberous root system underground, which acts like a pantry stocked for lean times. When care is inconsistent, those reserves are the only reason the plant survives at all.

Another detail often glossed over at the garden center is toxicity. Asparagus setaceus produces steroidal saponins, bitter compounds that function as a chemical “please don’t eat me” sign. These compounds can irritate skin when the sap contacts it repeatedly, and ingestion can cause gastrointestinal upset such as drooling or vomiting in pets.

They do not cause systemic poisoning, organ failure, or anything dramatic, but they are enough to make careless handling unpleasant.

This defensive chemistry is well documented by institutions such as the Missouri Botanical Garden, which provides detailed botanical profiles at https://www.missouribotanicalgarden.org. Understanding the plant’s real identity removes most of the mystery and prevents treating it like a fern that simply refuses to behave.

QUICK CARE SNAPSHOT

Care Factor	Practical Range
Light	Bright indirect light
Temperature	Typical indoor warmth
Humidity	Moderate to slightly elevated
Soil pH	Slightly acidic to neutral
USDA Zone	9–11 outdoors
Watering Trigger	Top layer of soil drying
Fertilizer	Light feeding during growth

The table gives a snapshot, but numbers alone do not keep a plant alive. Bright indirect light means the plant can see the sky without seeing the sun. A spot a few feet back from an east or north-facing window usually works, while a south-facing window needs distance or sheer curtains.

Putting it directly in a sunbeam because it “looks bright” leads to crisped cladodes and pale patches, a response known as photoinhibition where too much light overwhelms the photosynthetic machinery.

On the other end, parking it in a dim corner produces long, sparse stems that look like the plant is slowly giving up.

Light drives energy production, and energy determines everything else.

Temperature expectations are refreshingly ordinary. Asparagus setaceus likes the same indoor temperatures people tolerate without complaint.

Consistent warmth keeps metabolic processes stable, while cold drafts from windows in winter or sudden blasts from air conditioners stress the stems.

Stress shows up as yellowing and shedding, not immediate death, which tempts people to ignore the cause. What not to do is assume it will tough it out near a door that opens to freezing air, because repeated chilling drains stored carbohydrates faster than the plant can replace them.

Humidity is often overemphasized and misunderstood. Moderate humidity supports steady transpiration, which is the movement of water through the plant that keeps tissues firm.

Bathrooms without windows are often suggested because they feel humid, but without adequate light the plant slowly starves.

Chasing humidity while ignoring light is a classic mistake that leads to thin growth and eventual decline.

Soil pH being slightly acidic to neutral sounds technical, but in real terms it means using a standard houseplant mix that does not smell sour or feel muddy.

Extremes in pH interfere with nutrient uptake, and constantly adjusting soil chemistry is unnecessary and risky. Watering should be triggered when the top layer of soil dries, not when the calendar says so.

The plant uses more water when light is strong and growth is active, and less when days are short.

Fertilizer should be modest and limited to active growth periods, because feeding a slow plant is like force-feeding someone who is trying to nap.

WHERE TO PLACE IT IN YOUR HOME

Placement determines whether Asparagus setaceus looks lush or limp, and light quality is the deciding factor.

Bright indirect light supports dense cladode growth because it allows efficient photosynthesis without overheating the delicate tissue.

The fine structure of the cladodes exposes a lot of surface area, which is excellent for light capture but terrible for handling direct sun.

When intense rays hit those stems, cells lose water faster than it can be replaced, leading to crisping and permanent damage.

Direct sun also triggers photoinhibition, a protective shutdown of the photosynthetic system that shows up as bleaching or yellow patches.

This is not the plant “adjusting.” It is damage.

Moving the plant after that happens stops further harm but does not reverse the scars.

On the other extreme, dark rooms lead to open, leggy growth because the plant stretches its stems searching for light.

Energy production drops, tuber reserves are consumed, and the plant becomes fragile and prone to collapse.

Bathrooms are frequently suggested because humidity sounds helpful, but bathrooms without windows are a slow-motion failure.

Humidity does not replace light, and without enough energy production the plant cannot maintain its tissue regardless of how steamy the air feels after a shower. Airflow also matters more than people expect.

Stagnant air encourages pests and fungal problems, while gentle movement helps regulate transpiration. Placing the plant near a heater vent dries the fine foliage rapidly, pulling moisture out faster than the roots can supply it.

Cold drafts from poorly sealed windows shock the stems, disrupting water flow and causing sudden yellowing.

Light rotation matters because Asparagus setaceus grows toward its light source. Without occasional turning, one side becomes dense while the other thins out, leading to tangling and uneven weight distribution.

Roughly rotating the pot every couple of weeks keeps growth balanced. What not to do is constantly relocate the plant from room to room chasing the “perfect” spot. Frequent changes force repeated physiological adjustments, which drain energy and stall growth.

POTTING & ROOT HEALTH

Under the feathery top growth sits a tuberous root system designed for survival, not indulgence. These tubers store carbohydrates and water, allowing the plant to endure periods of drought or reduced light.

When the pot is oversized, excess soil stays wet long after the roots have absorbed what they need.

That lingering moisture fills air spaces in the soil, cutting off oxygen and creating anaerobic conditions that invite rot. Drainage holes are non-negotiable because water has to leave the pot for oxygen to enter.

A well-structured mix with bark and perlite improves oxygen flow by creating stable air pockets.

Compacted soil collapses around the tubers, suffocating them and encouraging harmful microbes.

Once anaerobic stress sets in, roots cannot respire properly, and the plant responds by yellowing and shedding top growth.

This is not thirst or hunger, and adding more water or fertilizer makes it worse.

Plastic pots retain moisture longer, which can be helpful in dry homes but dangerous if watering habits are heavy-handed.

Terracotta allows water to evaporate through the pot walls, providing a buffer against overwatering but requiring more frequent checks. Neither material is superior on its own.

The problem arises when pot choice and watering style do not match.

Repotting should be timed to active growth, typically in spring, when the plant can regenerate roots efficiently. Repotting in winter increases rot risk because metabolic activity is low and wounds heal slowly. After repotting, growth often pauses while the plant reallocates resources to root repair.

This is normal.

Forcing growth with fertilizer during this phase stresses the system.

Signs of anaerobic root stress include sour-smelling soil and sudden collapse of stems despite moist compost. For more on root respiration and soil oxygen, university extension resources such as those summarized at https://extension.umn.edu offer solid explanations grounded in plant physiology.

WATERING LOGIC

Watering Asparagus setaceus is less about volume and more about timing. During active growth, water use increases because photosynthesis and transpiration are running at higher speed. In winter, shorter days reduce light-driven energy production, and the plant naturally slows its metabolism.

Continuing summer watering habits into winter leaves the tubers sitting in wet soil they cannot process.

Light drives water use more than heat. A bright, cool room can require more frequent watering than a dim, warm one.

Soggy soil leads to tuber rot because oxygen is displaced, and roots suffocate before they decay. Checking moisture does not require digging around and damaging roots.

Pressing a finger into the top layer gives a rough idea, but pot weight is more reliable.

A freshly watered pot feels heavy, and a drying pot becomes noticeably lighter.

Learning that difference prevents guesswork.

A sour or swampy smell from the soil is an anaerobic warning sign.

That smell comes from microbes thriving in oxygen-poor conditions, and it means roots are under stress. Browning cladodes often signal dehydration, especially when the soil has dried too far and water uptake cannot keep up with transpiration. Bottom watering can help because it encourages roots to grow downward and reduces splashing on the fine stems.

What not to do is water a little every day.

Frequent shallow watering keeps the surface wet while deeper roots remain deprived of oxygen, creating the worst of both worlds.

PHYSIOLOGY MADE SIMPLE

Understanding how Asparagus setaceus functions removes most of the guesswork.

Photosynthesis occurs in the cladodes, which are efficient but delicate. Bright indirect light maximizes carbohydrate production without damaging tissue. Those carbohydrates are stored in the tubers, acting as a reserve that supports new growth and recovery from stress.

Turgor pressure is the internal water pressure that keeps cells firm.

When water is available and uptake matches loss, the plant looks full and springy.

When water loss through transpiration exceeds uptake, turgor drops and stems droop or crisp.

The fine foliage increases transpiration because it exposes more surface area to the air.

Low humidity accelerates this water loss, which is why extremely dry rooms cause browning even when the soil is moist.

Balancing light, water, and humidity keeps these processes in sync. Overcorrecting one factor while ignoring the others leads to stress responses that look mysterious but follow simple physiological rules.

COMMON PROBLEMS

Why are the cladodes turning yellow?

Yellowing cladodes usually indicate a mismatch between light and water. When roots sit in wet soil without enough oxygen, they cannot absorb nutrients efficiently, leading to chlorosis, which is the loss of green pigment.

The correction involves improving drainage and adjusting watering frequency, not adding fertilizer.

Feeding a plant with compromised roots increases salt concentration in the soil and worsens the damage.

Why are the tips browning or crisping?

Browning tips point to dehydration at the tissue level. This can come from low humidity, infrequent watering, or placement near heat sources. The physiology is straightforward: water loss exceeds uptake, cells collapse, and tissue dies.

The fix is consistent moisture and gentler air conditions. Misting the plant aggressively is not the solution, because brief surface moisture does not change overall humidity and can encourage fungal issues.

Why is growth thin and sparse?

Sparse growth means the plant is light-starved.

Without sufficient energy, it prioritizes survival over fullness, producing long stems with wide gaps. Moving the plant to brighter indirect light corrects the issue over time. Cutting back leggy stems can help redirect energy, but doing so without improving light simply results in more thin growth.

Why are stems turning reddish or purple?

Reddish or purple tones often appear under light stress or temperature swings.

Pigments called anthocyanins accumulate as a protective response. While not immediately fatal, this coloration signals that conditions are pushing the plant out of its comfort zone. The response should be gentler light and more stable temperatures, not drastic pruning.

Why is it suddenly collapsing?

Sudden collapse usually traces back to root failure, often from prolonged saturation.

When tubers rot, they cannot supply water regardless of soil moisture, leading to rapid wilting.

At this stage, reducing watering and improving aeration may save remaining tissue, but severe cases require removal of the plant.

Continuing to water in hopes of revival accelerates decline.

PEST & PATHOGENS

Spider mites are the most common pest on Asparagus setaceus and serve as a low-humidity indicator.

These tiny arachnids thrive in dry air and feed by puncturing cells, causing stippling and fine webbing.

Early signs include dull foliage and tiny pale dots.

Gentle washing and wiping with diluted alcohol disrupt their life cycle.

What not to do is ignore them until webs are obvious, because populations explode quickly.

Aphids occasionally appear on tender new growth, clustering on soft stems and excreting sticky residue. Removing them early with water or alcohol prevents deformation of new cladodes. Isolation is logical because pests spread through proximity and airflow.

Pathogens are less common but more serious. Fusarium root rot develops under constant saturation, invading stressed roots and blocking water transport.

Once established, recovery is unlikely.

Discarding the plant prevents spread to others.

Integrated pest management principles from university extensions, such as those outlined at https://extension.psu.edu, emphasize prevention through proper care rather than reactive treatment.

Keeping conditions balanced remains the most effective defense.

Propagation & Pruning

Propagation of Asparagus setaceus works best when it stays honest about what kind of plant it is, which means dividing the tuberous root system rather than fantasizing about seeds.

Beneath the soil sits a cluster of swollen storage roots that look like pale fingers and behave like a pantry. These tubers hold carbohydrates, meaning stored sugars produced during photosynthesis, and they power new shoots when conditions improve. When the plant is actively growing and not sulking through winter slowdown, those reserves are high enough that division becomes a reliable way to make another plant without weeks of suspense.

Trying this during dormancy or low light is a gamble because the tubers are already running on fumes.

Division works because each crown section contains meristematic tissue, which is plant speak for growth-capable cells, and those cells respond to cytokinins.

Cytokinins are hormones that stimulate shoot formation, and once a divided crown senses fresh space and adequate light, it reallocates stored energy into new stems.

This is faster and more predictable than seed propagation, which is why commercial growers do not bother sowing Asparagus setaceus indoors.

Seeds require berries, berries require flowering, and flowering indoors is a rare event unless the plant is older, slightly stressed in a controlled way, and receiving excellent light. For most homes, berries are more rumor than reality.

If berries do appear, usually red and glossy, they contain seeds and a higher concentration of steroidal saponins than the foliage. These compounds deter herbivores by irritating tissue, which is effective in the wild and annoying in a living room.

Handling berries or cutting stems can release sap that irritates sensitive skin, so pruning without gloves and then rubbing your eyes is a poor decision with predictable consequences.

Washing hands after pruning avoids a rash that feels disproportionate to the crime.

Pruning itself is not cosmetic indulgence. It redirects energy by reducing demand on older, tangled stems that shade newer growth.

Cutting back leggy or yellowing vines tells the plant to invest stored carbohydrates into fresh shoots rather than maintaining failing ones.

What should not happen is aggressive pruning combined with low light or soggy soil, because removing photosynthetic tissue while also stressing the roots leaves the tubers without a way to recharge. Pruning is a nudge, not a reset button, and used sparingly it keeps the plant dense instead of turning into a wiry green mess auditioning for a horror movie prop department.

Diagnostic Comparison Table

Cladodes in asparagus relatives differ fundamentally from true fern fronds.

Confusion around Plumosa Fern usually comes from the word fern, so comparing it directly to an actual fern and a closely related asparagus relative clears the fog without academic theatrics. The table below places Asparagus setaceus alongside Nephrolepis exaltata, the classic Boston fern, and Asparagus densiflorus, a cousin often sold under equally confusing common names.

Feature	Asparagus setaceus	Nephrolepis exaltata	Asparagus densiflorus
Botanical family	Asparagaceae	Nephrolepidaceae	Asparagaceae
True fern	No	Yes	No
Photosynthetic organ	Cladodes, which are modified stems	Fronds with true leaflets	Cladodes
Growth habit	Climbing, vining perennial	Upright to arching fern	Arching, bushy perennial
Typical indoor look	Fine, feathery, cloud-like	Broad, lacy fronds	Dense sprays of needle-like foliage
Toxicity	Mild GI upset and skin irritation	Generally non-toxic	Mild GI upset and skin irritation
Pet risk	Irritating if chewed	Low	Irritating if chewed

Asparagus setaceus and Asparagus densiflorus share the same family and similar chemical defenses, which explains why both cause gastrointestinal irritation when pets chew them. That irritation is not a dramatic poisoning scenario but it is enough to produce drooling, vomiting, or an offended stomach. Nephrolepis exaltata lacks those steroidal saponins, which is why it gets recommended endlessly to pet owners despite its own talent for shedding leaves when humidity drops.

Morphologically, the difference between cladodes and fronds matters because it dictates care.

Cladodes are tougher, more drought-tolerant structures than true fern leaflets, but they also scorch faster in direct sun because they are narrow and heat quickly.

Growth habit also matters for placement. Asparagus setaceus wants to climb or sprawl, while Nephrolepis insists on arching outward from a pot like a green fountain. Buying one while expecting the behavior of the other leads to frustration and unnecessary plant shuffling, which stresses roots and solves nothing.

If You Just Want This Plant to Survive

Survival mode for Asparagus setaceus is refreshingly simple once the urge to overmanage is suppressed. Bright indirect light does most of the work. A window that provides steady brightness without sunbeams landing directly on the foliage gives the plant enough energy to maintain dense growth without crisping.

Watering becomes easier when light is right because the plant actually uses what it absorbs. Letting the top layer of soil dry slightly between waterings prevents the tubers from sitting in stagnant moisture, which is how rot begins its quiet takeover.

Drenching the pot on a schedule regardless of light level is what kills this plant most reliably, so that should be avoided even if it feels attentive.

Support matters more than people expect.

Those delicate vines are climbers by nature, and without something to lean on they collapse into a tangled heap that shades itself.

A simple trellis or even discreet ties give the stems direction, reducing breakage and improving light exposure. What should not happen is forcing vines into rigid shapes or wrapping them tightly, because constricted stems bruise easily and interrupt internal water flow.

Humidity does not need to become a lifestyle.

Average indoor levels are acceptable as long as the plant is not parked beside a heater or air conditioner vent. Constant misting is unnecessary and can encourage fungal spotting if water sits on the fine foliage without evaporating. Fertilizer should be diluted and used sparingly during active growth.

The tubers store nutrients efficiently, so dumping concentrated feed into the soil burns roots and creates salt buildup, which interferes with water uptake.

Perhaps the most overlooked survival tactic is leaving the plant alone once it is placed well. Frequent relocation changes light intensity and direction, forcing the plant to constantly readjust photosynthesis.

That adjustment costs energy and results in shedding.

Pick a bright, stable spot, resist the urge to fuss, and the plant will quietly do its job without drama.

Buyer Expectations & Long-Term Behavior

Asparagus setaceus grows at a moderate pace indoors, which means it does not explode with new growth nor sit completely still.

During spring and summer, new stems unfurl and extend steadily if light and water are adequate.

In winter, growth slows noticeably because shorter days reduce photosynthetic output.

This seasonal pause is normal and not a failure of care.

Expecting constant expansion during low light months leads to overwatering and fertilizer misuse, both of which create problems that appear weeks later.

Over years, the plant becomes more vine-like.

Individual stems can extend several feet if supported, creating an airy curtain effect. Without support, those same stems tangle and break under their own weight.

Visually, older plants often look more dramatic and slightly less tidy, which is part of their appeal.

Trying to keep a mature plant looking like a compact nursery specimen requires constant pruning that weakens it.

Indoors, lifespan is measured in years rather than seasons.

With consistent care, Asparagus setaceus can persist for a decade or more, slowly accumulating tubers and producing thicker crowns. Relocation shock is real, especially when moving from bright retail conditions to a dimmer home.

Shedding often follows within the first month as the plant recalibrates. This is not a death spiral unless compounded by heavy watering.

Recovery usually takes a few weeks once light and moisture stabilize, so patience beats intervention.

New Buyer Guide: How to Avoid Bringing Home a Lemon

Dense crowns and flexible stems signal good root health at purchase.

Selecting a healthy Asparagus setaceus at the store saves months of recovery time. Crown density matters because sparse crowns indicate past stress or root damage. Stems should feel flexible, not brittle, because dehydration turns them fragile long before color changes appear.

Gently lifting the pot reveals useful information.

A pot that feels unnaturally light is often bone dry, while one that feels heavy days after watering may be hiding saturated soil and unhappy tubers.

Smell is an underrated diagnostic tool.

Healthy soil smells neutral or faintly earthy. A sour or swampy odor suggests anaerobic conditions, meaning roots have been deprived of oxygen.

That is not something to rehabilitate casually. Inspecting for pests involves looking closely at new growth tips, where aphids gather, and scanning for stippling that hints at spider mites.

Ignoring this step brings home an infestation that spreads faster than regret.

Retail conditions are rough on this plant.

Overwatering and underwatering both happen frequently under fluorescent lights and inconsistent staff care. Choosing a specimen that looks merely good rather than perfect is often wiser, because overly lush plants are sometimes propped up with heavy fertilizer that masks weak roots.

Patience after purchase matters. Repotting immediately, fertilizing immediately, and relocating immediately stack stressors that overwhelm even a healthy plant.

Letting it adjust before making changes prevents avoidable losses.

Blooms & Reality Check

Asparagus setaceus produces small white flowers followed by red berries under favorable conditions, but indoors this is uncommon. Flowering requires sustained bright light, maturity, and a stable environment. Many indoor plants never reach the combination of age and energy reserves needed to allocate resources to reproduction.

When berries do form, they contain higher concentrations of irritating compounds, which is why they should be removed promptly in homes with pets or curious hands.

Foliage is the main attraction and always will be.

The plant invests most of its energy into those feathery cladodes because they are its primary photosynthetic engine. Attempting to force blooms with heavy fertilizer misunderstands plant physiology.

Excess nutrients encourage soft, weak growth and salt accumulation rather than flowers. Stress-induced blooming, sometimes discussed online, is unreliable and often damages the plant more than it rewards the owner.

Appreciating this plant for its texture rather than chasing rare flowers leads to far better long-term results.

Is This a Good Plant for You?

Difficulty level sits squarely in the moderate range.

Asparagus setaceus is forgiving of missed waterings but unforgiving of soggy soil and poor light. The biggest risk factors are low light combined with enthusiasm, meaning frequent watering and fertilizing in a dim room.

Ideal homes provide bright indirect light, stable temperatures, and enough space for vines to sprawl or climb without being constantly rearranged.

Pet owners should think carefully. While toxicity is limited to irritation and stomach upset, the fine foliage is tempting to chew.

Households with persistent plant nibblers may prefer a true fern or another non-irritating option. Anyone looking for a plant that thrives on neglect in low light should also look elsewhere.

This plant rewards consistency, not indifference, and while it does not demand perfection, it notices when its basic needs are ignored.

FAQ

Is Plumosa Fern easy to care for? It is manageable rather than effortless. The care becomes easy once light and watering are aligned, but mistakes show up quickly because the foliage is fine and reacts fast to stress.

Is Asparagus plumosus toxic to pets? It contains steroidal saponins that cause gastrointestinal upset and irritation if chewed. This usually results in drooling or vomiting rather than severe poisoning, but repeated access is still a bad idea.

Is it a true fern? No, it is a member of the asparagus family and uses modified stems called cladodes for photosynthesis.

True ferns reproduce by spores and have fronds with leaflets, which this plant does not.

How big does it get indoors?

Vines can extend several feet over time if supported and given good light. The overall size depends on pruning habits and available space rather than a fixed genetic limit.

How often should it be repotted? Repotting every couple of years is usually sufficient once roots fill the pot. Doing it more often disturbs the tubers and slows growth, especially if done during low light seasons.

Does it flower or produce berries indoors? It can, but it is uncommon and usually limited to mature plants in excellent light. Foliage performance is a more realistic expectation than blooms.

Can it grow in low light? It survives but becomes thin and sparse, which defeats the purpose of owning it. Low light also reduces water use, increasing the risk of rot if watering habits do not adjust.

Why does it shed or brown so easily? Fine cladodes lose water quickly and respond fast to changes in light, humidity, or soil moisture.

Sudden environmental shifts stress the plant and trigger shedding as a protective response.

Is there a pet-safe alternative? True ferns like Nephrolepis exaltata are generally safer for pets.

They bring their own humidity demands but lack the irritating compounds found in asparagus relatives.
