Its leaf blades are 2–6 mm (0.079–0.236 in) wide and are typically flat, though leaves can curl inwards at their ends.

Its ovoid or ellipsoid panicle is 2–16 cm (0.79–6.30 in) long, with ascending, somewhat scabrous floral branches floriferous almost to their base.

Its ovate lemmas are 2–2.5 mm (0.079–0.098 in) long, are pubescent at their base, and become minutely serrulate at their tip.

Its panicles are smaller and more narrow, its floral branches are floriferous nearly to their base, and its spikelets are more crowded and more coriaceous than in P.
