... only these photos may not help in ID;
I do not recall who gave me the possible ID of Ischaemum commutatum !
It is not Ischaemum. Kindly spread out the spikelets and photograph so that the details are clear. Also approx height of the plant.
I will do my best to do the required when I get to the site and find the plant in that area.
Thank you very much for validating the ID.
