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

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 : 

 caly.x 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.

 lower petioled ; upper sessile ; even the upper floral as long as the (about 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. 005. — California, common in moist

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

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