often much shorter ; and the peduncle an inch or an inch and a half long. By an 

 error in transcribing, in Planta: Wrightiance the flowers are said to be 2-^ inches, 

 instead of 2\ lines, in length.

— Sides of mountains, at the copper mines. New Mexico, Aug.; in fruit. (1054.) 

 The same as Fendler's No. 186.
