* * Eoot perennial. 



-I— Corolla white or whitish, with tube shorter or hardly longer than the calyx-teeth ; lips only 2 

 or 3 lines long ; the upper villous-bearded or woollv on the back : flowers'sessile or nearly so : 

 herbage from soft-hirsute to white-tomentose. (Californian and one New Mexican species.) 



"S. Rothrockii, Gray. A span high, branched from the base, canescently lanate-pubes- 

 cent throughout : leaves all sessile and lanceolate, obtuse, almost entire (inch long) ; floral 



■ gradually smaller and oblong, subtending about 3 flowers: spike rather dense and short : 

 calyx campanulate; the teeth ovate- or subulate-deltoid, with very acute but soft tips: 

 corolla 4 or 5 lines long ; the tube included. — Proc. Am. Acad. xii. 82. — Zuni village. 

 New Mexico, Rothrock. 

 -S. ajugoides, Benth. A span to a foot high, villous with very soft white hairs : leaves 

 oblong, very obtuse, crenately serrate, 1 to 3 inches long, roundish or acutish at hase ; the 

 lower petioled ; upper sessile ; even the upper floral as long as the (ahout 3) subtended 

 flowers : clusters mainly distant : calyx short-campanulate or in fruit turbinate, very silky- 

 villous ; the teeth triangular-ovate, aristulate-acuminate, barely equalling the tube of the 

 corolla. —Linn. vi. 80, & DC. 1. c.474 ; Gray, Bot. Calif, i. 605. — Calif ornia, common in moist 

 ground. Also (in a dubious form) Willow Spring, Arizona, Rothrock. 



S. albens, Gray. Tall (1 to 5 feet high), soft-tomentose or lanate with white or whitish 

 wool, leafy : leaves oblong or ovate, usually with more or less cordate base, acutish, cre- 

 nate, 2 or 3 inches long; lower short-petioled ; upper nearly sessile; most of the floral 

 shorter than the dense interrupted capitate clusters of the virgate spike : calyx turbinate- 

 carapanulate; the teeth triangular and aristulate, nearly equalling the tube of the corolla.

 high : leaves oblong-ovate and subcordate, obtuse, crenate, 2 to 4 inches long, mostly rather 

 long-petioled; floral all reduced to small bracts of the dense oblong or cylindraceous spike 

 (of 1 to 3 inches long), each subtending about 3 flowers: calyx-teeth deltoid, mucronulate, 

 very hirsute, fully equalling the tube of the corolla : upper lip of the latter strongly 

 bearded. — PL Hartweg. .331; Gray, Bot. Calif, i. 005. — California, in the Coast Range,
