 plant glandular-puhescent and wet as if with dew; leaves ascending, 

 linear-lanceolate, IJ to 3 in. long, all entire; lower leaves with long

 C. stenantha Gray, to which this is closely allied, occurs from Mon-

 Oakland Hills; San Francisco; etc. Mar.-May. The large lower 

 leaves have three strong callous nerves. Bracts very Icng, the lobes

 varying to linear-lanceolate or -oblong, entire or with a few linear- 

 laciniate lobes, IJ to 2| (or the lower even 3J) in. long; bracts petal-like 

 above, equally 3-parted or the middle lobe somewhat larger and 

 3-cleft at summit; spikes lax below; calyx-lobes colored red, rarely
