For Id 230708JM2: In the wet bed of Himmat Sagar Lake in Hyderabad, AP on 20/7/08.


I think you have taken pictures of Dark Grass Blue on Alternanthera paronychioides. The flowers of this exotic weed can be used in greeting card after being pressed and dried.


Thanks, …, for Id help.
Here are a few links for pictures & details of Alternanthera paronychioides (Smooth Chaff-flower):

After further checking the description of Alternanthera paronychioides given at http://www.efloras.org/florataxon.aspx?flora_id=600&taxon_id=242412161 with my pictures & pictures of Alternanthera paronychioides at http://89sky.net/vbb/showthread.php?p=11624, I feel my species is not Alternanthera paronychioides.
It quite matches up with Alternanthera sessilis, posted earlier at Indiantreepix link.
Here is the Wikipedia link for Alternanthera sessilis.

Experts may pl. confirm.


A.sessilis has linear leaves whereas your plant has orbicular or obovate leaves. The plant is A. pungens which is a native of Central America, naturalised in India. Another difference (you can see through a lens) between the 2 species is that the latter has spinescent heads and the tepals are dissimilar which is not so with A. sessilis. My book gives picture of A. sessilis which differs from yours. I do have a picture of A. pungens which tallies with yours.

This plant from Hyderabad by … as per feedback in the thread has been wrongly labelled as A. pungens at FOI website.


It doesn’t look like A. pungens.
It may be Alternanthera paronychioides.


Yes surely Alternanthera paronychioides

Alternanthera again from Hooghly 13/11/12 sk2: Found this Alternanthera in a wet field, this morning.

Species : Alternanthera paronychioides A.St.-Hil. ?
H & H : prostrate herb, part semi erect, in a moist field
Date : 13/11/12, 10.30 a.m.

Place : Hooghly


A. philoxeroides has flowers in heads on axillary long peduncles

This is typical A. paronychoides


Thank you very much for introducing me to two more Alternanthera. I remember the discussion in my previous post.

Now wondering whether have neglected it considering it to be stunted growth of common Alternanthera.

I do not know if it is distributed in Konkan / Western Ghats.

This is Alternanthera paronychioides A.St.-Hil., previously identified in efi thread.


Yes … Excellent photographs.


Thank you very much Sir, once again.

I remember my blind arguments regarding the ID of another Alternanthera, last year.

Chenopodiaceae and Amaranthaceae Week : sk-03 : Alternanthera sp.: I am not sure of the ID of this species and i found it on the margin of agri-land, a mat forming prostrate herb.


I think, based upon the keys at – efi thread, this species is also Alternanthera paronychioides A.St.-Hil.

Alternanthera paronychioides A. St.-Hil. = Alternanthera ficoidea (L.) P. Beauv. as per GRIN :

Alternanthera paronychioides A. St.-Hil. = Alternanthera ficoidea (L.) P. Beauv. as per GRIN updated in 2013.
Should we follow the same ?


FLOWERING PLANTS OF INDIA, DICOTYLEDONS, Vol-I (AcanthaceaeAvicenniaceae) authored by S. Karthikeyan, M. Sanjappa and S. Moorthy and published by BSI, Kolkata in 2009 also does not mention it (Alternanthera paronychioides A. St.-Hil.). Pl. see Alternanthera.


Yes, Karthikeyan et al.(2009) does not mention A. paronychioides A. St.-Hil. as they consider it a synonym of A. polygonoides R.Br. ex Sweet, which itself is mentioned as synonym of A. sessilis (L.) R.Br. ex DC. by The Plant List. Thus A. paronychioides A. St.-Hil. and A. polygonoides R.Br. ex Sweet becomes synonyms of A. sessilis (L.) R.Br. ex DC. But again Plant List considers A.paronychioides A. St.-Hil. as a distinct species with a specimen in Herbarium catalogue of Kew: (http://apps.kew.org/herbcat/getImage.do?imageBarcode=K000583029) which resembles to a species growing in India and identified as A. paronychioides A. St.-Hil. (particularly in Uttarakhand).
I feel that A. paronychioides A. St.-Hil. and A. ficoidea (L.) Sm. are two different species.
However, … Sir may have a better idea of it.

May we have your views in the matter pl.


I feel the two are too distinct to be merged. The specimens that I have collected/photographed leave no confusion.


Thanks, … I will follow accordingly at efi site.

Thanks … Any photograph with flowers?


I only have a single picture of this, … thanks to the ‘time factor’!


Enclosing a relatively closer view of flowers of this species. Though flowers are visible at lowest branching in … picture. Thank you … for showing another aggressive weed of Tropical and Subtropical areas in India.


Enclosing a relatively closer look to flowers in this species.


Nice to see the pattern of branching


Alternanthera a big genus from the family.
Always confusing to go to species level.
Thanks for showing this prostrate plant growing widely as weed.

A tiny plant seen in grasslands.

Gomphrena Species?


Alternanthera ficoidea syn. tenella


I too agree with …


Yes from me also. Common here. It is a weed in the open land outside my house.


I feel it is more closer to images at Alternanthera paronychioides rather than those at Alternanthera ficoidea


Thanks for the correction..

These Gomphrena and Alternanthera Species are getting confusing for me.
