Emma and I examined specimens collected from this site and we are of the opinion that these plants are Dichanthium sericeum. The leaf sheath is covered in tubercle-based not restricted to the node; racemes between 2-5 per inflorescence though generally 3-4; pedicellate spikelets sterile; absence of distinctive purplish colouration as present in D.setosum. A shame is not the rare one but I must say that this is a super nice patch of a grass that isn't super common regionally.
