ooker & Arnott, Bot echey, p. 402, distinguish hos 
bs 0 al J. Menziesii, with chins ae riety 
Californicus, with acuminate ones; found, in all th 
specimens, examined by me, the outer sepals acuminate and 
the inner ones obtuse, with or without a mucro; but in some, 
as stated before, the outer ones are much shorter than, in 
others as long as, the inner ones.

While this ~_— was in the hands of the printer I received a mo 
orneage collection of Arizona Plants, made last year by Drs. Likott 
Coues, and Riper. Palmer, in which I found good s ‘speciinens of this
