bellate peduncles, occasionally subtended by one or more leaflets; 

 fruit oblong, 5 mm. broad, 8 mm. long, deeply immersed in the rigid 

 disc; exocarp spongy, light pink before maturity, the appendages at 

 the summit of the cocci conspicuously horned, with accessory interme- 

 diate crests. 



Habitat: — A low-branching shrub, the long divergent branches in- 

 clined to support themselves on adjoining bushes, but never decumbent. 

 Flowers in April, fruit July; only known from a single locality in the 

 interesting botanical district of the Napa Valley. Though closely allied 

 to C. proslraius, with which, in herbarium specimens, it is easily con- 

 founded, it is clearly distinct in habit and foliage, as well as a widely 

 different geographical range. Like all the species of this Section, the 

 explosive character of the capsules is very apparent to any one who 

 would undertake to collect fully mature seeds.

Since the revision of Cliorizanthe, in Proceedings of Davenport

 ining typical specimens, as well as extended observations and collec- 

 tions in the original localities requires the following changes in the de-
