76 CovlUc — Xew Plants from Soatliern. California, 



in the tliroat of tho corolla ; anthers oblong; ovavy and included 

 style sparingly short hairy ; style ti})s very short, divergent ; 

 capsule narrowly ovate, bluntly acute, 8 to 4 mm. long ; seeds 

 apparently very numerous, oblong, angulate Ijy compression, 

 scrobiculate, 5 mm. long. 



The ph\nt closely resembles a small congested specimen of 

 Pcritylc evionji. The form of the leaves is very similar to that in 

 F. rotu.ndifolia, but the plant, while l)elonging to the subgenus 

 Eittocii, differs from all its s})ecies in l^eing suffrutescently peren- 

 nial. The cream-white corollas form another conspicuous char- 

 acter.
