Looks very similar to my posted plant of A.sessilis….?


This was posted on our group earlier and identified by … (Garden Plant for ID 180111 AK-3)


That is the reason I posted my reply. Let others recheck it.


Alternanthera sessilis in FoC = (leaf) apex acute or obtuse
Alternanthera sessilis in FoP = (leaf) blunt to shortly acuminate at the apex
Alternanthera sessilis in FoNA = (leaf) obtuse to acute
Alternanthera ficoidea (L.) P. Beauv. in PIER = acute and mucronate at the apex, attenuate at base and narrowed along poorly defined petiole….
The plant in this thread doesn’t have acute leaf-apex but, certainly the apex is mucronate and it resembles the picture at the PIER site.

Requesting Id of this wild plant with peculiar arrangement of leaves which are rough to touch.
not flowered as yet

If I have to guess, I will go for Alternanthera ficoides (Amaranthaceae). However, the flowers will appear soon to make ID easier.


??  Ruellia tuberosa L. of Acanthaceae


Thank you … and … for a possible Id. hope to see the flowers


the plant has flowered. attaching pics of the same. it is looking like Alternanthera ficoides (Amaranthaceae) as you have said. requesting to confirm the Id.


Yes it is A.ficoides. After few weeks it will make larger clusters of flowers in axil of leaves.

Thanks, …, for the id.
Seems to match with images at Alternanthera ficoidea
Does not matches with images at Alternanthera sessilis

It is not listed in Nepal …!

Pl. check for its synonyms.

Alternanthera paronychioides A. St.-Hil. is listed in Nepal Checklist, which is a synonym of Alternanthera ficoidea as per GRIN(once known to be very reliable, but now I think have been shut down & link not opening). This is basically an American plant. So GRIN is going to be most reliable.

Thank you all. Need such a deep exploration.

Alternanthera for ID : 090711 : AK-2:
Found growing wild at Nasik, Maharashtra on 14/4/2008.
Again a very tiny plant with White flowers.
Is this ‘Khaki Weed’ or ‘Smooth Chaff Flower’ from Flowersofindia?
Alternanthera pungens or A paronychioides?

Please check Alternanthera paronychioides. It is not A.pungens because A. pungens stem is generally prostrate.


It is neither Alternanthera pungens (with broader leaves and shaply pungent perianth tips) nor A. paronychoides which is much softer plant. It could be A. ficoides which shows a lot of variation. I am uploading all three from my collection.


Alternanthera ficoides

efloraofindia:”For Id 30062012MR1’’ is this wild plant Alternanthera spp at Pune:
June 2012 Pune
Would appreciate your help to Id this wild plant ht about 2 feet, leaves 8 cms X 4cms and white flowers .
8_IMG_0770_1 shows an oblong green yellow structure about 1 cm in length I don’t know if it is the fruit. Is it some Alternanthera spp?


Its Alternanthera species of Amaranthaceae…..


this is Alternanthera species for sure, but i am equally sure that the plant in last pic 8_img_0770_1 does not posses that oblong structure.
it might be some part of other plant fallen on this plant. the fruit of an alternanthera species is an utricle which is enclosed in the bracts and is very small, almost equal to the flower. please check the plant part.


Thank you … for your reply. Fortunately the plant still exists where I had seen it. I have checked the plant for the oblong structure and it was no longer seen. You are right it must be a part of some other plant. There is a big tamarind tree around with flowers. As I was there a similar looking structure fell down probably it is a bud of the tamarind tree.
The wild plant has grown a little taller than before and what I observed today was that the flowers are in pairs at every point if that could help the species identification.


Yes of course it is Alternanthera, which some websites would make you believe as A. paronychioides

Alternanther paonychoides is, however, a much different plant, with delicate, smooth, creeping stems, and much smaller leaves:
This plant is Alternanthera ficoidea in which yellowish flowers often emerge from chaff like bracts.
http://www.indianaturewatch.net/displayimage.php?id=293955
The species is one of the most commonly cultivated edging plant and shows a lot of variability in cultivation, with species originally taken as distinct species having been merged.

Alternanthera ID1 from Hooghly 21/10/12 sk1:
Very interesting find in “The Plant List” relating to FoI species :- FOI

Species : Alternanthera paronychioides A.St.-Hil. ?
H & H : wild herb in rural roadside, waste place, rail tracks
Date : 27/10/12, 3.50 p.m.
Place : Hooghly
Some similarities –

Alternanthera ficoidea


There are at least two Alternanthera ficoidea in The Plant List –

  1. accepted name Alternanthera ficoidea (L.) Sm. = syn. Alternanthera tenella Colla BUT NOT with any synonym as Gomphrena ficoidea.
  2. synonym Alternanthera ficoidea (L.) R. Br. = accepted name Alternanthera paronychioides A.St.-Hil. = syn. Gomphrena ficoidea L. BUT NOT with any synonym as Alternanthera tenella.
GRIN has Alternanthera ficoidea (L.) P. Beauv. = Alternanthera tenella Colla = Gomphrena ficoidea L. (basionym)
Which one do i take?

The Plant List seems to be making mess of things. I am tired of pointing out their mistakes. A. ficoidea (L.) Sm. is not recorded in IPNI, the most authentic source of Plant names. Please also note that in the Plant list there is no synonym which has Linnaeus as the author. If not Gomphrena ficoidea then what is the basionym of A. ficoidea (L.) Sm. My frequent advise to members that if the name exists in GRIN, it is better to follow it.
I agree there is lot of confusion in the net, but A. paronychoides is a soft stemmed plant of wet grounds, often found along banks of drains, streams and river banks. It is totally creeping and rooting herb. I have photographed and collected it both in Delhi and Kashmir.

So, i have now Alternanthera ficoidea (L.) P. Beauv.
Will try to find out Alternanthera paronychioides also.

Very good photographs.


Great pictures … To me this looks like A. ficoidea mainly due to the gregarious habit with more or less erect branches, and stalked leaves.


Many thanks … for validating this post.
Was always thinking the contrary – that A. sessilis is of gregarious habit. Also had the thought that the width of leaves of A. ficoidea is larger than the length. Many thanks for straightening my thoughts. Will revise my notes at flickr very soon.

Alternanthera Species?

Alternanthera sessilis


Sorry, …, it’s not sessilis, variety of ficoidea only,


Thanks, …, for the id.
I think many cultivars are coming of this as per

Or is it due to some deficiency ?


These were seen growing wild near a lake along with normal green colored ones.
In multiple places in that area, not just one.

Garden plant for ID :180111 : AK-3:
Taken at Muscat, Oman on the 4th of March,2010.


It is a weed seen in wastelands and abandoned farms in Mumbai also.


Alternanthera pungens for me too.  Very common in Chennai as a weed.


Yes  Alternanthera pungens a weed in West Bengal too


Any other species of Alternanthera?


Yes … Your doubt is genuine. The leaves of A. pungens more or less rounded in outline, and perianth with sharper tips. This could be A. ficoidea.


I go for Alternanthera ficoidea

Alternanthera for ID : 090711 : AK-1:
Taken at Jijamata Udyan, Mumbai, Maharashtra on 29/12/2007.
Very tiny leaves, a small plant, cultivated.

This is Alternathera ficoidea, now including several species formerly treated separately. Common edging plant. A. paronychioides is much different plant, recently uploaded by me.

Earlier uploaded at eFI.


To me appears more closer to images at
https://efloraofindia.com/2011/02/04/alternanthera-ficoidea/


I went through both pages in eFI site … Alternanthera ficoidea and Alternanthera sessilis … I find that the leaves are variable in both pages, both are sessile.
Please let me know of some “visual” characteristic in the posted plant that suggests A. sessilis, so that I can look for it in my observations before upload.

Pl. check the pubscence of the leaves and nature of the flowers and its head closely.


OK, thanks, …
Will revise to A. ficoidea.
More of my Alternanthera observations will get uploaded in due course, and maybe I will keep fumbling; I do not seem to get familiar with this genus 🙂

Yes Dinesh ji the two species are very distinct, A sessilis is a plant of wet places, softer stems and leaves latter often gradually narrowed and obtuse and flowers in dense nearly globose to oblong cluster without sharply projecting bracts. A. ficoides on the other hand prefers exposed habitats leaves and stems are stiffer, leaves often prominently narrowed towards base and flowers in few flowered clusters, with distinctly projecting bracts and perianth.

Please see my post  of A. sessilis

Thanks very much, …, for the clarity and simple keys.
I hope my further uploads will be with proper IDs.

Alternanthera sessilis or ficoidea:
Is this Alternanthera sessilis or ficoidea?


A. ficoidea


Alternanthera sessilis or ficoidea
The leaf morphology and flowering pattern is almost same for both plants.
Sessilis is a smaller herb, predominantly aquatic plant, growing around water bodies,  smaller leaves and a pinkish central hue of flowers. This is native plant of India and eaten in some places.
Ficoidea is taller shrub,  terrestrial, bigger leaves and has bigger creamy flowers. This is a alien weed from South America and infestation from North to South India.
Please explain any other differences?
