this is mostly found in moist places. I think this is Arthraxon lancifolius, Pl confirm the ID


Its not A.lancifolius for sure. Could be A.prionodes Need close up focus of spikelets for species confirmation.

show basal portion of stem. Also close up of sessile spikelet from both sides.


This was out in the field so I won’t be able to send these additional photos now.


Arthraxon prionodes

The amplexicaul leaf base and awned spikelets are characteristic of Arthraxon

This is most probably Arthraxon prionodes as it is the most common found in this region. A close up focused photo of raceme and spikelet would reveal a row of spines on glumes of the sessile spikelets and if you pull out the awn, you will find that the awn arises from the basal part of lemma.
