grass Setaria ID from Hooghly 8/10/12 sk1: This is a very common grass growing along roadside, edge of ditches and waste places. I was waiting for its inflorescence and found a few today.
Species : Setaria palmifolia (J.Koenig) Stapf ?
Habit & Habitat : roadside, edge of ditches, waste places, shady places, height 2.5 feet, but can grow more; leaf avg. 19 cm or more x 4 cm, stem all over hairy
Date : 8/10/12, 8.45 a.m.
Place : Hooghly
The dense inflorescence and hairy stems suggests it is Setaria poiretiana. However, wait for some more time for the whole inflorescence to mature and post the close up of mature spikelets and inflorescence. Definitely not S.palmifolia whose general appearance of the population itself is different.
Attaching images of the same grass taken today (11/10/12). This grass is all over hairy, including both surfaces of leaves.
A correction in description – stem of this grass is not hairy, long trailing and purple coloured, yet to see if there is any root on the nodes.
Wonderful ! Yes it is Setaria poiretiana. Kindly check local floras to see if it is a new record for Bengal.
This used to be one of my favourite grasses for flower arrangement in Kerala Agricultural University.
