Sir,
Found this grass beside a BALI-KHAD (don't know the English term, it is a medium to large water body created by evacuation of sands, long long ago). But BALI-KHAD is secondary, though it has a story, long long ago it belonged to my grandfather (maternal) whom, unfortunately, i never met.
The primary concern is the grass, Though it looked like images available of Phragmites karka in the net, yet i think it has amplexicaul leaves. The last three pics of inflorescence(with purplish spikelets) is from another individual, half km away from the first one.
Species : CONFUSED
H & H : about 10 feet high, stem hollow, leaves avg. 60 cm x 5 cm, both sides glabrous
Date : 14/11/12, 12.01 p.m.
Place : Hooghly
Thank you & Regards,
surajit
