Corolla half an inch long; upper lip nearly equalled by the oblong large — 
A. vaGans, Gray. : 
Corolla smaller and narrower; its tube surpassing the upper sepal. 
A. BREWERI, Gray. 
A. OrcutTTriaNumM has been collected within the last year or 
two, mainly by Mr. C. R. Orcutt, near San Diego, and also a 
adjacent parts of Lower California. At first it was thought to 
be possibly a small-flowered state of A. Coulterianum. Some-— 
times, as in that species, the spiciform raceme bears hardly any 
filiform branches: sometimes they are produced in extreme — 
abundance. “a 
A. NIVENIANUM was collected by the Rev. Mr. Nevin at San_ 
Juan Capistrano, Los Angeles Co., in 1882. I think we have 
an immature specimen of the same from near San Diego. It 
much resembles the foregoing except in the seeds. : 
. SUBSESSILE we have from Santa Catalina Island, collected : 
by Mr. Schumacher in 1878; from Chollas Valley, San Diego 
Co., by Mr. Orcutt, 1883; both in fruit; and specimens from 
near San Diego, collected by Mr. Cleveland in 1874 and 1879, 
young flowering plants, appear to be of the same species, although 
they had been taken for A. Nuttallianum. The sessile leaves — 
and short-peduncled flowers ought to distinguish it.
