Kooskooskie valley. Two feet high; very bushy and very succulent.

This is exactly H. capitatum, Douglas, from the Columbia, and H. 
densiflorum, Nutt., from the same country; but it is, I think, very dif- 
ferent from the Californian plant of Mr. Bentham, included under that 
species, and which is the speciosum of Nutt. in Herb. Hook.—g. is 
smaller, segments of the leaves less serrated or laciniated, and capitula 
sessile; but I dare not venture to consider it as more than a variety.

A most distinct and well-marked species, with copious, singularly - 
stout, spreading stems and branches, and. firm downy-leaves. Noone _ 
else appears to have met with it, except Mr. Nuttall, whose specimens, — : 
now before me, were also gathered in‘ Colorado of. the Rocky Moun- 
tains.” -It is probably a very local plant. |
