This one again from the same sandy patches, in front of my school. I would like to add that a few months ago truckloads of sands & laterite (?) has been dumped there, to be used for road filling later.


Attaching key in Bengal Plants and relevant links, not sure if this plant can be same –
Thank you,


It is not so easy to identify Cyperaceae members just looking at images of the plants. I need to dissect the spikelets to confirm the identity. So without mature specimens it is difficult for me.
