Notes.
Most closely related to Poa tenera and P. clelandii differing
from the first in the conspicuous pigmentation of the sheath, its tufted habit
and smaller hairy lemma with ciliolate margins. From P. clelandii it
differs in the smaller more slender plant, fully connate sheath (compared with
2/3 connate), broad decurrent ligule (vs. narrow non decurrent), and variable
hairiness of the lemma.

Endemic.
