15. S. tortuosus Koll. Shield Plant. Annual; stem branching from the 

 base, eree'l, olU'ii busli-like, sometimes nearly simple, 1 to 5^2 feet high, sometimes 

 reduced and 3 to 6 inches high; herbage glabrous and glaucous; blades of lower 

 leaves obovate to spatulate-obovate, 14 to 1 inch long, contracted at base to a petiole 

 as long; blades of upper leaves becoming oblong- to ovate- or orbicular-cordate, 

 entire, sessile and clasping, Yz to 1% inches long, mostly l^ to 1% inches broad; 

 sepals purplish, connivent; petals rose-purple or white and purple-veined, 2i/^ to 

 6 lines long; pods recurved-spreading, lYz to 4% inches long, 14 to 1 line wide; 

 stigma small, sessile; seeds orbicular, narrowly winged. 



"Montane, 2000 to 7000 feet: Sierra Nevada from Tulare Co. to Tehama Co.; 

 outer and middle Coast E-anges from Siskiyou Co. to Monterey Co. June- Aug. 



Note on the flower. — The flowers are somewhat bilabiate, a little by reason of structure, a 

 little by reason of position of parts ; that is to say, the upper pair of petals elongate sooner than 

 the lower and are always somewhat longer. Similarly the upper pair of the 4 longer stamens are 

 longer than the pair on the lower side of the flower. The two short stamens have each a lateral posi- 

 tion and barely show at the mouth of the corolla ; their acute or mucronate anthers, however, have 

 upturned points and thus belong on the upper side of the flower.

Var. orbiculatus Hall. Annual ; stems many from the base (or more commonly from a 

 short erect axis 1 or 2 inches long), 3 to 6 or 9 inches high; flowers smaller (2^/^ to 4 lines long), 

 darker purple. — High montane, 7000 to 10,500 feet: Sierra Nevada; high North Coast Ranges 

 from Humboldt Co. to Siskiyou Co. Within its high altitudinal range, this form is fairly con- 

 stant but has no character which separates it decisively from the prevailing form of the species 

 at lower altitudes. Moreover, numerous intermediates occur, doubtless equaling in number of 

 individuals either the species or its variety.
