•*-■*-•*-■*-- Involucres sessile and solitary {often secund) along the ascending and 

 usually long-virgate branches of the open naked dichotomous ])anicle : 2)eren-

 sparingly branched, the branches more or less elongated and virgate: invo-

 foot or two high, rather slender : leaves oblong- to linear-oblanceolate* \ to 1 inch 

 long, often with smaller ones fascicled in the axils, tomentose on both sides or less 

 so above, acute, narrowed at base : bracts all small and triangular : involucres

A variable species ranging from the lower Sacramento (Corral Hollow, Bracer) to San Diego, 

 and eastward to New Mexico ; the variety in the Sierra Nevada and W. Nevada. At high alti- 

 tudes the inflorescence is sometimes reduced to 2 or 3 involucres almost capitate upon a slender 

 dwarfed scape ; Mt. I'inos, at 8,500 feet altitude, Rothrock.

 sparingly branched, a half to a foot high, rather stout : leaves rounded or obovate, 

 obtuse, G to 8 lines broad or less, cuneate at base, on a short thick petiole, densely 

 tomentose both sides : branches of the cymose panicle short and somewhat spreacl- 

 ing : bracts larger, subfoliaceous, triangular to acute-oblong : involucres \\ to 2 lines 

 long ; teetb acute : flowei-s rose-colored, 2 lines long, the sepals aj)pressed to the 

 nearly glabrous akene, which is more abruptly narrowed at base. — Proc. Am. Acad,

 base, a foot or two high, often withcnit branches : leaves usually somewhat scattered, 

 oblong-lanccolato or sometimes nearly ovate, about an inch long, acute, narrowed to 

 a short petiole, becoming glabrate above : bracts ovate-triangular to lanceolate, 

 acute, rarely somewhat elongated : involucres 2^, to 3 lines long, obtusely toothed, 

 distant on the few elongated branches : flowers white or rose-colored, 1 to 1^ lines 

 long : ovary glabrous. — Bot. Sulph. 45 & DC. Prodr. xiv. 14 ; Torr. & Gray, 1. c.
