Vegetative - leaf sheath (closed or open) open
Vegetative - leaf width (measured at widest part) 12-15 cm
Vegetative - leaf glabrous or with trichomes glabrous
"Vegetative - ligules
(absent/membranous/hair-like)" ciliate
"Vegetative - auricles (claw-like/overlapping
rounded/lobed or absent" absent
Spikelet (sessile or stalked (pedicel)) pedicilate
Spikelet (shorled, opposite or distichous (on 1 or 2 sides) on the inflor. Axis (rachilla) distichous - lower 3 mm and upper 3.2 mm
Floret - 1st glume (lower one) lower - 1mm and 0.33 lenth of spikelet. upper- +/- the size of the lower glume
Floret - 2nd glume (sometimes modified or absent) both more or less 3mm
Floret - lemma (lower and larger bract, typically with odd # of veins (nerves)) 3mm many veined
Floret - palea (upper, smaller bract, 2 veins and parially enveloped or enclosed by the lemma) 2 veins on outter edges, papery and delicate, about the same length and width between the upper and lower

Broadly ovate calyx lobes with "broad erose scarious margins" (Kearney & Peebles) offer the clearest distinction from P. dasyphyllus (which typically blooms in spring anyway).
