Dear All,
I really think it is impossible to identify grasses and sedges from
photos, however good. The keys of these families and others like
Eriocaulaceae require characters not observable in the photos of the
kind circulated here. The Cyperaceae keys are highly technical even at
generic level and any attempt to simplify identification of these will
only lead to misidentification. I know at least four Cyperaceae
experts and none of them will give an identification based on photo.
In addition, the generic names have often been merged, split, changed,
so Cyperus of one might be Pycreas of another and so on and so forth.
Considering the diverse nature of the family and the taxonomic rigour
required for identification I request none here to take a short cut in
identification.
There are excellent keys for Cyperaceae of certain regions like
Maharashtra and Karnataka which can be a starting point. Otherwise
a proper specimen should be sent for identification to experts like
Dr. V. Prasad of BSI (presently at Kew gardens) or Dr. Henry Noltie at
Royal Botanical Gardens Edinburgh.
I feel the same about identification of Poaceae and Eriocaulaceae.
