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.
