NEW CALIFORNIAN UREDINE. 
By P. Drstet. 
By the kindness of Mr. Holway I have received numerous 
Uredinex from California, which in part are new or have not 
been sufficiently distinguished hitherto from similar species. 
The specimens have been collected by Mr. W. C. Blasdale, 
Berkeley, Prof. A. J. McClatchie, Pasadena, and Mr. E. W.

have already been described in Hedwigia (1893, pp. 29, 30), 
and in the Botanical Gazette (1893, No. 7). In the following 
we give descriptions of a further series of them. 
Uredo coleosporioides, D. & H. Sori on the stems and 
under surfaces of the leaves, orange-red. Spores ovoid to 
oblong, echinulate, with colorless membranes, 22—30 x 15— 
25 wu 
On Castilleia foliolosa. Berkeley, Cal., June, 1893, leg. 
Blasdale. In its general appearance this species resembles

formed, as is the case in this genus, in chains. 
Uredo Castilleiw, D.& H. Sori dark brown, almost con-
