females seemed to come out an hour before males. first individual seen at 9:51am; temperature ~80s, mostly cloudy.

update: another "population" on Sawtelle

photos are labeled in the file name with upper and lower spikelets (florets?) called out. Just learning grasses so please let me know if i used any of the wrong terminology.

life cycle (annual or perennial) annual
underground stem perennials (rhizomes or stolons) no
Inflorescence type (spike, raceme, panicle or glomerules) panicle
Culm length 59-70 cm
leaf (simple, basal or cauline) simple?
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
awn (if present, at the apex of glumes or lemmas) abset
Flower (bisexual/unisexual/sessile and hypogynous) bisexual

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