P. CANOS()-B.\i'.iiATUM, Kellogg in Proe. Calif. Acad. ii. 15, — described from a .specimen col-

 "colored" corolla with "lower lip slightly 2-notelied, eariuate, densely bearded below, mostly at 

 the extremity, with whit(! or long transpaicnt frosted hairs," — is a complete ]iu/./le. As the 

 tube iif tlic'iiiroUa i.s siiiil to bu "nhoit, like that of P. brcvijbrus," it nniy belong to that 

 species. 



P. KOSTUiFLOiui.M, Kellogg, 1. c, from the same source, — said to have linear-lanceolate leaves, 

 narrow creamy-yellow corolla, with linear and acute lobes to the lower lip, — is wholly confound- 

 ing in its characters.
