Cyperus seen growing wild on the mountain slopes in Lonavala on 16/9/2010.
Since i do not know technicalities my process is alternative finding. First i note what species can be found in my area, thereafter some gross character like habitat, height etc. Then i try finer detail.
Flora of British India describes some 61 Cyperus, add to this figure Pycreus & Juncellus. This makes it nearly impossible.
Since … plant is from Maharashtra, first i need a “Bengal Plants” like book, thereafter other characters.
