Acmella species for ID 17/01/2012 SMP2:  Attaching pictures of an Acmella species observed in Sinhagad valley near Pune.
Habit : Herb found near rice fields. Nov 2011
Height of the plant 1to 1.5 feet.
Flower heads 1cm or so.

I tried to read the key for Acmella but it seems to be difficult for me unless I see several other species from the genus.
Taking a short cut route for ID.
For me it looks like Spilanthus paniculata (S.acmella)
Spelling is also different at diff sources here it is from BSI Flora of Mah.
I hope Acmella radicans with white to yellowish-white corolla. Heads are yellow in A paniculata

Looks like Acmella oleracea to me.
Thank you ..., but it doesn't look like Acmella oleracea to me.
I think Acmella oleracea as suggested by ...
Thank you Sir, i thought florets are greenish white and 4-merous.
On reconsideration perhaps you are right, Acmella radicans var. radicans
Earlier upload on the group perhaps had younger heads. Yes often confused with A. oleracea but whitish heads and 4-merous heads are distinctive. Thanks for pointing out.

Nice pictures of Spilanthes (now Acmella), may be A. radicans.
Yes I think ... is correct this plant surely looks like Acmella radicans
Acmella species indeed
Acmella radicans var. radicans
Acmella radicans observed in Sinhagad valley Pune in Dec 2011.
Corolla white with purple tinge.
Nice photos ... Many thanks for sharing this Acmella.
I am hesitant about uploading my sightings - not confident about my IDs.
We have a interesting and educative upload by ... Spilanthes acmella confusion.
Eagerly waiting for uploads of
  • Acmella calva (DC) R. K. Jensen
  • Acmella ciliata (Kunth) Cass.
  • Acmella oleracea (L.) R. K. Jensen
  • Acmella paniculata (Wall. ex DC) R. K. Jensen
  • Acmella radicans (Jacq.) R. K. Jensen var. radicans

Initially I was hesitant to accept this ID suggested by ... as this species is not mentioned in BSI Flora Mah. but as per the Key suggested by him it has to be correct.
Certainly no doubts of ... ID, ...
But these Acmella (earlier popular as Spilanthes) are confusing to me.
Forgot to add another common species Acmella uliginosa (Sw.) Cass.
Hoping that the confusion gets cleared with various uploads.

Spilanthes radicans Jacq. is a native of Mexico and Central America and considered as Invasive Alien Species in India. Species is found in almost all the India. It reached Pantnagar few years back with construction material (sand) and spreading now.
The Plant list 2010 mentions this species as Acmella radicans but I have followed here the name as mentioned by Karthikeyan et al. 2009 in their document “Flowering Plants of India Dicotyledons- Vol-I (Acanthaceae –Aviceniaceae).
Now known as Acmella radicans var. radicans
Good photographs ...

Date, Time: 16 DEC 12 11:57am
Habitat: wild, along trail to the falls, growth on wall made of cut-rocks.

This acmella has been capture recently at Nahan at 700mt. It looks me as Acmella radicans. what is your opinion.
I think seems to match with images of this species at Acmella
Yes A.radicans to me too.
I think it is not known earlier from Himachal Pradesh. A native of Tropical America and Mexico, this species is spreading rapidly in India.
