posted pics. of Rotala floribunda (Ammania floribunda).
Local Marathi name : Machim
pics taken at kas plateau near Satara, Maharashtra in Sept 2009.
..., not certain whether this plant is indeed R. floribunda as you have put.
Referring Shrikant ji's FOS pg 176, the illustration looks different. 
Comments from friends welcome for validation of the posted plant's ID.
This looks like Rotala densiflora.
THE PLANT HAS MUCH RESEMBLENCE TO Rotala floribunda.. but to be checked for its bifid stigma...
..Anyhow.. if its R.floribunda... present collection may be its extended distribution as it was confined to Mahableshwar hills, and above1500 msl...
thanx for ur reply and add. info.
i am sorry my pics are not clear to confirm the bifid stigma. i checked my other pics too.
Characters are needed.
This species is not Rotala floribunda but R. densiflora.

... saw similar looking plant Rotola acquatica as Ided by Dr. Almeida near a river at Sawantwadi, Mah. posting the same separately.
Rotula aquatica Lour. is from Boraginaceae and it is a hardy shrubby plant in  the stream beds--common in SGNP.
This plant is Rotala............LYTHRACEAE
1. Leaves 3-nately whorled......R. occultiflora
1. Leaves opposite..................R. densiflora

Many thanks ... the leaves look opposite for sure, it is difficult for me to make out whether it is 3-nately whorled.
Will get better views diuring my next visit.
looks like allied to R. densiflora. Provide all characters.
Flowers and habit look like
Rotala densiflora

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
