DESCRIPTION OF A NEW SPECIES 
By P. BEVERIDGE KENNEDY 
While making a preliminary botanical survey recently in 
the vicinity of Soda Lake in the Carson Sink region, Churchill 
county, Nevada, I was surprised and delighted to come across a 
plant which was an entire stranger tome. I could not even

In Emory’s Notes of a Military Reconnoissance 143. raat 
Torrey and Gray inention the genus under the name Dicoris, 
but without description. The plant listed there, the one upon 
which D. canescens, the type of the genus is founded, is said to 
have been 5 to 6 inches long and 4 to 5 inches wide, while our 
plants were at least two and a half feet high and two feet wide. 
The Geological Survey of California, Botany, 1: 615. 1876, how-
