 crown : leaves membranaceous, lanceolate-spatulate, entire or obsoletely denticulate, ob- 

 scurely 3-5-nerved, 1 to 3 inches long, attenuate into a shorter margined petiole : spike 

 slender but densely flowered, an inch or more long : bracts and sepals short (only a line 

 long), pale with greenish midrib, little over half the length of the oblong capsule. — N. W.

 pubescent or glabrate, and with the dense or sparsely-flowered spike a span to a foot high ; 

 bracts broadly ovate or roundish, convex, scarious-margined, sometimes pubescent-ciliate : 

 sepals roundish-obovate, scarious except the fuscous or greenish midrib : corolla-lobes 

 broadly oval or ovate: capsule (2 lines long) ovoid, slightly exceeding the calyx. — Ann.

 P. Richardsonii, Decaisne, 1. c. 698. — Moist and saline soil, Colorado, N. California, and

 lines wide, gradually tapering into long margined petioles : scapes equalling or surpassing 

 the leaves, bearing an oblong dense spike (in fruit 2 inches long) ; the rhachis, &c, tomen- 

 tose or pubescent : bracts round-ovate or oval, fleshy-herbaceous and scarious-margined : 

 sepals similar : corolla-lobes oval : mature capsule ovoid-oblong (3 or 4 lines long), sepa- 

 rating from the base and then fissile : seeds narrowly oblong. — Linn. i. 106 ; Bong. Veg.
