1 have r«'ferred my plant aa above without liaving seen any spocimons of that 

 species. It differs from the descriptiou lu some slight details aud it has not 

 been collected so far north before. 



The foliage is rather coarse, but Dr. I'almer writes that the white flowers are 

 very attractive and he thinks it would be a good plant for ornamental cultiva- 

 tion.

Other specimens, with similar leaves, but with smaller heads, were collected^ 

 which are provisionally referred here. No. 932. The staminate plant was found 

 very common about Colima, along streams, January 9 to February 6, 1891

To this species, apparently, should have been referred Palmer's No. 389, from 

 Alamos.

I find no character except the pubescence to distinguish these specimens, and 



it appears very doubtful whether there should bo two species recognized, as; 



some botanists hobl.
