Rotala serpyllifolia (Roth) Bremek., Acta Bot. Neerl. 3: 149 1954. (syn: Ameletia tenuis Wight; Ammannia tenuis Clarke in Hook.f.);
.
Rotala serpyllifolia is annual or perennial in permanent water. In India, it is widely spread in southern, central, eastern and northwestern India (Bihar, Gujarat, Karnataka, Maharashtra, Andhra Pradesh, Madhya Pradesh, Rajasthan, Uttar Pradesh and West Bengal) and also seen in Bangladesh and Pakistan (Cook 1996; Pullaiah and Chennaiah 1997).
It grows submerged in rivers, streams and lakes but is also found in standing water recedes. The shoots are often tightly packed and turf-forming (Cook 1996). It grows in seasonally inundated areas and flowers as the water recedes. The erect stems are often dense and cushion-forming (Joseph and Sivarajan 1989).

Found in water stream In evergreen forest Bhimashankar wls 26/12/13 … Rotala tenuis. No such species is mentioned in the following: A New Species of Rotala L. (Lythraceae) from Kerala by K. Subrahmanya Prasad and K. Raveendran (Keys of 25 species found in India of which 15 are endemic to Paninsular India\
As per the Plant List: Rotala tenuis Koehneis an unresolved name.
This name is unresolved, but some data suggest that it is synonymous with Ammannia tenuis (Wight) C.B.Clarke
As per your flickr post references, Flora of Eastern Ghats & efloraofindia, it should be Rotala serpyllifolia (syn: Ammannia tenuis Clarke in Hook.f.) Yes, Rotala tenuis Pl. see Flora of Eastern Ghats & efloraofindia
Also A New Species of Rotala L. (Lythraceae) from Kerala by K. Subrahmanya Prasad and K. Raveendran (Keys of 25 species found in India of which 15 are endemic to Paninsular India)
It is in conflict to all these. I couldn’t open the document. Rotala serpyllifolia is the correct name of Roata tenuis For me it is Rotala serpyllifolia (Roth.) Brem. Rotala tenuis is a synonym of R. serpyllifolia.
I was on usual bird photography trip to Dangs in Southern Gujarat, which is northern limits of Western Ghats falling in Gujarat….
I found this plants growing everywhere in 5-6 streams, ….Their color was so contrasting and beautiful red I could not resist to click some pictures….and some samples to identify them later along with try to put them in my planted aquarium….. It’s kinda mat-forming plants with a creeping stem up to 5-15 centimeters long, rooting at nodes which come in contact with wet substrate. At first glance it looked like Ludwigia Spp. but later found out all Ludwigia have yellow flowers where as this one has red/purple kinda small flowers….There leaves were very small say .5 to 1 cm in emerged growth and submerged growth has slightly longer leaves say 1 cm. and a bit longish… Here are some pics…..As I just returned from 2 days trip straight to office I will take some more shots of collected specimen emerged and submerged growth later tonight when at home….and share with you tomorrow… Date/Time-02/12/2012 Location- – Ahawa, Dangs, Gujarat Habitat- Wild Plant Habit – Herb? Height/Length- 10-15 CM stems I think the photos have been mixed up. The image 8700 seems to be Rotala floribunda … any chance of Rotala tenuis than R. floribunda for 20121202_120554__MG_8700-ed2-rs.jpg ? None of the images are mixed up….. I agree with … on ID for all images. Does not matches with images at http://www.arkive.org/rotala/rotala-floribunda/image-G137174.html
I think close to images at Rotala serpyllifolia (Roth) Bremek.
Date- 25/12/19
Location- Madhe ghat Western ghats pune Habitat Type-WILD Plant Habit-Herb Height/Length- 5 to 10cm Other: grows near water body Rotala serpyfolia (Roth) Bremek ?? Yes. Matches with images at Rotala serpyllifolia
I think the correct spelling will be Rotala serpyllifolia (Roth) Bremek. .
Rotala tenuis Koehne . Which rotala? at Kerwa Dam, Bhopal: 2 high res. images. Rotala serpyllifolia (Roth) Bremek. Yes Yes, as per images at .
Can it be the dried state of Rotala species? Looks like species of Selaginella No, it’s a flowering plant. Can it be some Aerva ? A. lanata ? It may be some Acanthaceae member, leaves opposite I do not think so as per images at I could not find anything close as per comparative images at I tried many families like Acanthaceae, Amaranthaceae etc., but could not reach anywhere close. Checked Lythraceae also. If it is a flowering plant, then check Rungia muralis. Sorry it is not Rungia as it is not a one sided spike. Rotala serpyllifolia. You have finally nailed the id.
Appears close as per images at
https://efloraofindia.com/2013/06/04/rotala-serpyllifolia/ I have gone through Rotala species two times earlier for its id but could not pinpoint it.
