looks like Umbrella palmCyperus alternifolius
it popps up in disturbed land near water boies and high rain areas in the north eastern India including West Bengal…
the fan/umbrella shaped is very popular with flower arranging ladies esp for ikebana…
lots of seeds are produced, self seeds

It looks like the same as in /species/a—l/cl/cyperaceae/cyperus/cyperus-alternifolius. I saw this plant in Alipore Hort., later i also noticed it growing in the wild, beside a residential house.

Please also see Cyperus involucratus at – http://davesgarden.com/guides/pf/showimage/218974/#b.
FoC informs while Cyperus alternifolius is naturalized in many tropical areas Cyperus involucratus is widely cultivated.
