164 POLEMONIACEAE 



one, sometimes 4 lobes go to form the upper lip and only 1 the lower. The cleft between the lobes 

 of the lower Up is usually deeper than the clefts in the upper lip or between the upper lip and 

 lower lip. At Cima, in the eastern Mohave Pesert, this species is frequent on the Ivanpah Valley 

 floor. The plants at that locality exhibit chiefly two marked corolla patterns: (1) upper lip of 

 corolla with 4 lobes, the 2 uppermost lobes of the 4 forming a pair and marked alike with a purple 

 pattern, the 2 lateral lobes of the 4 forming a pair with a common color pattern, while the lower 

 lip, consisting of a single lobe, is destitute of a color pattern; (2) sometimes the single lobe of 

 the lower lip "captures" a lateral lobe of the upper lip, in which case the corolla consists of an 

 upper lip of 3 lobes all marked alike and a lower lip with 2 lobes colored or marked alike. On the 

 sandy plain about Essex, on the southeast side of the Providence Mts., where this species is abun- 

 dant, the corolla appears to be uniformly with 3 lobes in the upper lip and 2 in the lower, and 

 without color patterns. Sometimes, apparently, there are colonies in wliich the corolla is sub- 

 regular or only obscurely bilabiate.

5. H. virgata Benth. Monterey Gilia. Stem mostly erectly branched from

 tomentose when young but soon glabrate or nearly so; leaves filiform, entire or the 

 uppermost with a pair of short lobes at base, Yo to 1% inches long; flowers in rather 

 large (9 to 11 lines long) broadly turbinate heads, the heads 6 to 8-flowered, ter- 

 minal or borne along the stem or branches in the leaf-axils and either subsessile or 

 on short or long branchlets ; body of the heads 5 to 12 lines broad, conspicuously 

 surpassed by aU or some of the lobes of the palmately 3 to 5-divided bracts ; bracts 

 and calyces densely woolly; calyx-lobes markedly membranous-margined (as also 

 in all the vars.) ; corolla tubular-funnelform, blue (the throat yellow), 7 to 9 lines 

 long, the throat scarcely exceeding the subulate calj'x-lobes; corolla-lobes % to as

 throat, the filaments inserted at base of throat ; anthers 1 line long.
