292 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
and tomentulose at the base, nearly or quite glabrous above; 
bracts of the involuere about 13, occasionally becoming dark 
brown or almost black in the dried state.—California: near 
Mendocino, 14 July, 1904, J. W. Congdon (Mo. Bot. Gard. 
Herb. No. 83706); Melburne, Mendocino Co., 10 Aug., 1905, 
James McMurphy (U. S. Nat. Herb. No. 691260); Vance’s 
Camp, Humboldt Co., 16 June, 1911, Huron H. Smith 3844 
(Field Mus. Herb. No. 296049). 
Inasmuch as the collections of this plant in California have 
been made in the vicinity of lumber camps, it is most probable 
that it has been introduced in connection with the extensive 
lumber trade between California, Australia, and New Zealand. 
The species apparently has become well established on the 
Pacific coast and is gradually spreading, but to what extent 
it may become disseminated in this country remains to be 
seen.
