I had some doubts regarding the identification of Indotristicha ramosissima here.
As per the species description (genus key, description) Indotristicha is filiform, free floating and attached to rocks. The plate diagram also shows the morphology. Please refer to the attached document on Podostemaceae in Kerala by Mathew and Satheesh, 1997 pg 247.
The images here have zygomorphic flowers and so cannot be Indotristicha ramosissima. The same error in ID seems to have been validated at FOI as well.
Please find attached, images of Indotristicha ramosissima from rivers (Kumaradhara) in Dakshin Kannada. Would be curious to know what others think. Please let me know.

yes it seems different
Perotis indica. a grass species.
Thanks, … But actually that is not correct.
OK. I was doubtful about this !
Thanks for the responses. I am still unclear why the identification is disputed. The description in the cited literature seems to match.
Thanks, … Sorry. In fact, I confused myself totally. Thanks for clarifying the matter.

Images of Indotristicha ramosissima in FOI may not be correct as per discussions in Regarding Indotristicha ramosissima
Don’t have much idea about this. But again, cannot see any similarity in the images of Indotristicha ramosissima here and the attached image from the paper.
