200 SMITH: STUDIES IN THE GENUS LUPINUS 
L. microcarpus ? B barbatus Gray in Hb. Kew 
art fr. Hb. Hook. The plant which Agardh, from Hb. Lindl., under L. micro- 
carpus, refers to as ‘huic proximum,’ and identifies with Dougl. Calif. 
“Thus it is evident that neither Agardh nor Gray considered 
this plant to be typical ZL. microcarpus. The name “barbatus”’ 
is not now available, as it has been applied by Henderson to an 
Oregon lupine of the Polyphylli. 
Barbatissimus, “very much bearded,” refers to the very shaggy 
calyx, etc.

Apparently confined to the foothills about San Diego. It is 
probable that all the specimens listed above should not be in- 
cluded under one and the same name. Considerable variation 
exists and it is ae that none of them should be included in
