This is Azolla filiculoides, which can be seen from its radiate
thallus-shape, not A. pinnata subsp. asiatica, which has a more triangular
shape and is pinnate, not radiate.
A. filiculoides is adventive in India, presumably introduced deliberately
in connection with rice-cultivation due to the nitrogen fixation of the
associated Blu-green Algae, but in recent decades it has become quite
widespread throughout. There are two very close subspecies, subsp.
cristata (originally of American origin), which is confirmed from Kashmir
(where it used not to occur some 30 years ago), and subsp. filiculoides
(originally of European and Old World origin), which is confirmed from
Nepal and Calcutta.
The two are very closely similar and require careful microscopic
examination of the number of cells in the little leaf-hairs and in the
glochidia, hairs on the reproductive sporangia. The full distribution (so
far) of the two subspecies in India is not further known pending study of
more populations.
Cheers,
Chris Fraser-Jenkins, now in Tokyo University (returning to
Kathmandu soon).

Forwarding again for Id assistance please.
Some earlier relevant feedback:
This plant is Azolla spp., a pteridophyte, may be A. pinnata
Thanks
