KosTeLerzkyA preirara, Gray. Mr. Pringle’s no. 3622, from — 
Tamasopo Cafion, San Luis Potosi, collected in J une, 1890, appears 
identical with the type of this species discovered by Dr. Palmer on | 
the Yaqui River, Sonora, 1869. Mr. Pringle’s specimen shows the 
plant to be erect and over two feet in height. The cauline leavee 
are divided into three linear-oblong, subequal lobes, and have 
addition two smaller auricles at the base; the leaves of the branches . 
are simply linear, or have auricles of varying length at the base. : 
The flowers in a dried state appear to be white with a yellow tint. — :
