Myriophyllum aquaticum (Vellozo) Verdcourt, Kew Bull. 28: 36 1973. (Syn: Enydria aquatica Velloso; Myriophyllum brasiliense Cambess.; Myriophyllum mattogrossense Hoehne; Myriophyllum proserpinacoides Gillies ex Hook. & Arn.);
Parrot feather is a perennial plant. Parrot feather gets its name from its feather-like leaves that are arranged around the stem in whorls of four to six. The emergent stems and leaves are the most distinctive trait of parrot feather, as they can grow up to a foot above the water surface and look almost like small fir trees. The woody emergent stems grow over 5 feet long and will extend to the bank and shore. Attached to the Parrot feather are pinkish-white flowers that extend approximately 1/16 inches long. As the water warms in the spring, parrot feather begins to flourish. Most plants flower in the spring; however, some also flower in the fall. Almost all plants of this species are female, in fact there are no male plants found outside of South America. Seeds are not produced in any North American plants. Parrot feather reproduces asexually. New plants grow from fragments of already rooted plants. The plant has whorls of feathery blue-green to waxy gray-green leaves deeply cut into many narrow lobes.
Parrot feather is now used for indoor and outdoor aquatic use. It is a popular plant in aquatic gardens. It spreads easily and has become an invasive species and a noxious weed in many areas. The plant can be introduced to new areas when sections of its rhizome are dug up and moved. In Florida in the United States, flea beetles have been found to use parrot feather as a host for their larvae.

From a quick look this seems to fit. There is only one species of Myriophyllum recorded from Nepal – which is M.spicatum.
The situation is more complicated in Kashmir – which I plan to comment about in due course.
