L. GERMANORUM Cham, grows near the coast of San Luis 

 Obispo Co. and may be expected further southward. It is a low- 

 branching species, destitute of glands, with yellow flowers, the 

 outermost of which have irregularly cleft corollas. 



L. ALBIFLORA Eastwood, Bull. Torr. Club xxxii. 217 (1905), 

 comes from Rose Station, Kern Co. Its sharp-pointed leaves, 

 numerous glands, and white flowers should distinguish it if found 

 within our borders. 



L. LEMMONI Gray, Proc. Am. Acad. xxi. 412 (1886), first de- 

 scribed from Arizona specimens, has been collected at Indian 

 Wells, Kern Co., by M. A. Knapp, also by Hall & Chandler, no. 

 7373, and at Little Owens Lake, Inyo Co., by Purpus, no. 3055, 

 both localities being in the Desert Area just north of our borders. 

 It has a lower habit than L. glandulifera, the numerous branches 

 low and spreading, but can scarcely be distinguished from that 

 species except by the style-branches, which are prolonged into 

 conspicuous subulate tips.
