Identification of grass requested. : 6 posts by 2 authors. Attachments (2)
I am attaching 2 images of a grass species collected from high altitudes at Easternghats.
the plant is about 50 cm in height. 

Pseudanthistiria hirta

Thank you …, for your efforts, but the plant list or Gamble FPM has no such species, whether it has any synonyms. I am thankful to you if my doubt is clarified.

need free specimens for identification. interesting species for me  

A specimen was handed over to BSI Deccan circle for identification, they too could not, only 2 plants are located in the interior, if I could I will collect more

If I get free specimens of above grass (with inflorescence) then I could try for name. My tentative remark about grass is seems to be interesting species.

Sorry, the species name was spelt wrongly. It is Pseudanthisthiria hispida.

Wild grass seen today (19.11.21).
Themeda Species?

Pseudanthisthiria heteroclita

This is again new to me.
Currently I am in Nasik, which has a lot of grasslands.
So I’m finding new ones.

Grass seen earlier in Nov at the base of Borgad Conservation Reserve.

Pseudanthistiria heteroclita (Roxb.) Hook.f. ??

I also think it should be Pseudanthisthiria heteroclita, seeing the general habit, long white bristles and top leaves.
Many of the sheets of Themeda quadrivalvis and Pseudanthisthiria are misidentified in many herbaria. Kindly check if the awn is hairy or glabrous. Themeda will have hairy awns visible under a hand lens, whereas Pseudanthisthiria awns are glabrous. This is one of the best method to differentiate the two. Also see if there are involucral spikelets and how many (sterile spikelets covering the raceme containing fertile spikelets). Other characters like hairyness, tubercle based bristles on leaves, spathes or glumes are all variable and are found across many similar genera.

I will have to wait for the next rainy season to click more images.
