Pentstemon Palmeri, A.Gray in Proc. Amer. Acad. Sc., vol. vii. p. 378, and 
vol. viii. p. 291. Watson in U.S. Geol. Explor. 40th Parallel, Bot., p. 
220. 
The first notice of this noble species was drawn up by 
Professor Asa Gray, from a cultivated plant supposed to have 
been raised from seeds collected in Utah; and it has since 
been fully described from dried specimens collected by Sereno 
Watson during the Geological Exploration of the 40th Parallel, 
who gives as its habitat in the work quoted above “ Arizona ; 
foot-hills of the Trinity, West and East Humboldt Mountains 
in Nevada, alt. 5-6000 ft., June, July. Also from Southern 
Utah (Palmer).” The figure we give is from a specimen of a 
secondary branch or shoot, forwarded by Mr. W. Thompson, 
of Ipswich, who flowered it in August of the present year from 
American seeds ; he informs me that it attains a height of three 
to four feet, from which, and Watson’s attributing to it a 
stature of two to five feet, I judge that it must be altogether 
the grandest and most beautiful known species of the genus. 
Though coming from so southern a latitude, 32°-42° N., 
appears to be quite hardy. 
Descr. Quite glabrous and glaucous, except the inflores- 
cence, which is described as minutely glandular pubescent in 
NOVEMBER Ist, 1873.
