toothed or entire, sessile and auriculate-elaspinf?, the teeth callous-tipi)ed; flowers 

 5 to 6 lines lonpr; calyx commonly deep purple, 3 upper sepals approximate or con-

 darker; claws broad, the limbs eurved-spreadiufj:; lon<;est pair of filaments often 

 connate for their entire lenp:th and with reduced anthers; pods curved, more or 

 less spreading:, {glabrous or hispid, 2 to 3 inches lon^, 1 line wide; pedicels 4 to 4^^ 

 lines long:; seeds elliptical, narrowly winged. 



Middle altitudes, 1000 to 2000 feet : Coast Ranges from Mendocino and Solano 

 Cos. to San Luis Obispo Co. Apr.-June. 



Note on variation. — Streptanthus glandulosus is a polymorphic species. Its leaves vary 

 from hispid to nearly glabrous; they are of varying shapes and degrees of dentation but are 

 narrow and, except the lowermost, more or less auriculate at base. The calyx varies in color from 

 pale purple to nearly black and in shape from slender (not saccate) to conspicuously saccate and 

 almost inflated. The petals are almost equally variable in color, size and shape. The pods in 

 position are erect, spreading, or descending.

Var, albidus Jepson. Stem very stout and erect, 2 feet high ; herbage glabrous and glaucous 

 above, some scattered pubescence only on lower part of stem and lower leaves; leaves like S. 

 glandulosus; raceme strictly bilateral; flowers large (6 lines long); sepals white-margined and 

 -tipped, purplish below; petals with limb conspicuous, crisped, white with purplish veinlets; pods 

 erect, stout, 3 inches long. — Hillsides south of San Jose. Apparently this has been collected only 

 by Rattan (in 1886 and 1887). It has some claims to specific rank but is so little known that we 

 leave it in varietal status until more ample material is available. Volney Rattan writes : "I found 

 the Streptanthus west of the Oak Hill (Catholic) Cemetery, four miles south of San Jose. It 

 grows on the nw. slope above the [Cincas] creek which closely hugs the base of the hills on the 

 west" (Jepson, Botanical Letters of Other Days, p. 232. ms.). 



Var. pulchellus Jepson. Stem generally branching, 4 to 12 inches high; herbage pubescent 

 throughout; leaf -blades oblong-linear to oblong-lanceolate, with opposite salient teeth; raceme 

 often subsecund; pedicels hairy, 1 to 2 lines long; sepals commonly very slightly hispid; pods 

 commonly a little hispid, at least the lower ones. — Dry ridges, Marin Co.
