Requesting to please ID this shrub captured in a dried up paddy field near Devgad, Konkan, Maharashtra in November 2012.
Is it Rotala rosea?

Rotala rosea

it is a herb I think….what about Ammania?…


Attaching a cropped pic for arriving at the correct ID…

Due to the presence of large petal that exceeding the calyx lobes, stem clasping leaf bases I suspect the specimen is of Rotala densiflora. Please check whether the style is present and capsule is enclosed within the calyx tube, then you can confirm the identity as R. densiflora.

Please id this small plant with tiny red flower found in sandy area
Mumbra, Maharashtra

This is a species of Rotala possibly R.rosea.

Appears to be same as in the efi thread: Rotala sp for ID-200811-PKA1: 

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)
I am marking the mail to …- may be he can help us in the matter.

I think it is Rotala densiflora

It is very hard to identify Rotala sp. from photographs. For correct identification floral characters are needed.

Requesting to please validate ID of this small plant captured near Satara, Maharashtra in October 2014.
Is this Rotala densiflora?
This looks similar to the plant posed by me earlier, although from a different area

It seems to be Ammannia baccifera L.

Attaching a cropped version, sorry for not attaching it earlier… Attachments (1)

It is Rotala densiflora (Roth) Koehne only

The photograph attached is that seems to be Rotala rosea or R. densiflora. Please observe the following characters for confirmation. If it is R. rosea the leaf bases narrow, cuneate, petals minute, capsule well exceeding the calyx tube, style minute. If R. densiflora leaf bases cordate or obtuse, petals bigger and showy exceeding the calyx lobes, capsule up to the level or slightly above the tube, style prominent.

I also think closer to images at Rotala densiflora (Roth) Koehne rather than those at Rotala rosea (Poiret) C. D. K. Cook ex H. Hara


Kas week:: PKA44:- Rotala sp. ??:
Seen this herb near a water stream at Kas.. Looks like some Rotala sp.

Appears closer to images at Rotala densiflora (Roth) Koehne

Seen in a wet channel from leaking water from a small water hole.

Yes it is also Rotala densiflora (Roth) Koehne

Going by flowers, it appears more closer to Ammannia auriculata Willd.

Sorry, on further examination, it is closer to Rotala densiflora (Roth) Koehne only.

Identification required. At Horsley Hills, Andhra Pradesh

Welcome … Any Lythraceae member like Rotala species ?

It is…. Rotala fimbriata of Lythraceae

Thank you … for identifying. I got confirmation from BSI CNH also. Thank you … for your concern. Finally its confirmed that its Rotala fimbriata. 

Does not match with images of Rotala fimbriata as identified earlier.
Should be some other species of Rotala.

Rotala densiflora


On 18/10/08 in Narshapur forest, AP around 80 Km. from Hyderabad. Seen in slightly wet water-logged area. I hope Id is correct.

Does not matches with images of Rotala densiflora
Can it be R. mexicana as per illustration at ?

It is obviously not R. mexicana because it is an apetalous (petal less) Rotala species. By flower construction and habit it is close to R. densiflora, but seemingly different also. Please make a critical analysis, probably turn out to be a new species.

Yes it’s Rotala densiflora

It’s Rotala densiflora (Roth) Koehne
