diffusely branching from the base : corolla larger, irregular, the 3 upper 

 petals approximate, ascending, the lower one remote from these and 

 declined, the middle lobe of each attenuate to a claw and far surpassing 

 the others. —Very common in the Mt. Diablo Range.

 vi. 532 (1865), under Eucharidium: C. Saxeana, Greene, 1. c. 140. Gla- 

 brous, 1 — 2 ft. high : leaves lanceolate, entire, short- petioled : calyx-tube 

 slender, more than 1 in. long, abruptly dilated at base : corolla irregiilar; 

 petals round-obcordate, with a linear-spatulate middle lobe proceeding 

 from the deep, or rather shallow sinus and far exceeding the others : 

 filaments clavate ; anthers densely white-villous along the sutures, erect 

 after dehiscence as before : capsule sessile, 1 in. long, curving away from 

 the stem : seeds large, tuberculate, conspicuously winged. —On Mt. Oso, 

 Stanislaus Co.^ Brewer, and near the G-eysers in Sonoma Co., Dr. Saxe. 

 Very erroneously described in the "Botany of California" as having "a 

 narrow subulate lobe in the deep sinus."

 reddish and glaucous, erect, 1 — 6 ft. high, simple or somewhat branching, 

 stout and rigid : leaves broadly ovate to linear, repand-dentate : petals

 with a densely hairy scale on each side at base : capsule }-^ — % in. long, 

 stout, sessile, 4-angled, somewhat curved, often hairy. — On open or half-
