Fits the description of D. setosum, as distinct from D. sericeum, in that it has fewer flower head branches (2-3), unstalked spiklets are longer (5-6mm), and the upper spikelet is male

Just realised that I had reported plants at this locality as Dichanthium setaceum on 22 March 2020.
Possible that I misidentified them ?

@EmmaCook - this would be a significant range extension of this nationally vulnerable species and another threatened species for Crace Nature Reserve - do you think you could make a collection and confirm ID.

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.

Thanks Matt
I also submitted a sample to the ANBG. The reply from Helen Kennedy also suggested Dichanthium sericeum subsp, sericeum
