Bothriochola pertusa (You can observe the single pit on the lower glume of sessile spikelet)


Or Bothriochloa bladhii


Could be, …


B.bladhii will have more no pits on sessile spikelets, whereas B.pertusa has one single pit on the sessile spikelet, which is clearly visible. Also, the silvery white hairs are also characteristic of pertusa. Since the inflorescence is mature and more branched, it is looking like B.bladhii superficially from a distance, but a close up reveals that it is B.pertusa only.

Ready for dispersal:
A poaceae member is ready for the dispersal of seeds.

Are those seeds or dry flowers falling off?


I think … is correct.
I could see the hairy stigma in the second picture. This could be some infection. The other inflorescence/branch of inflorescence, in which flowers are yet to open, seems healthy.


I think It is Dichanthium sp.


May be it is Bothriochloa sp. but no details to confirm.
