On Epilobium coloratum: JoDaviess, Sept. 20, 6019, IT. 
Persoon described (Syn. Fung. p. 219) Uredo pustulata 
var. epilobii, and DeCandolle wrote Uredo epilobii (Flora Franc. 
II. p. 226), and Fuckel described the teleutoform and referred 
the uredo to same species. The name Uredo pustulata, Pers., 
has been used for various species. 
M. crotonis, Burrill. 
IL, 11]. Amphigenous. Uredosori scattered, rather prom- 
inent, circular, cinnamon-colored; uredospores obovate, sharply 
echinulate, produced on pedicels, 15-21 by 18-27 »; teleutosori 
irregular, scattered or somewhat confluent, slightly elevated, 
reddish brown; teleutospores irregular, mostly elliptical or ob- 
long, one, two, or more celled, arranged in an irregular layer 
composed of variously imbricated spores, smooth, cell-contents 
granular, pale to dark brown, 11-15 by 30-42 ». 
Trichobasis crotonis, Cooke. Amphigenous; sori minute, subrotund, 
surrounded by the ruptured epidermis, fuscous: pseudospores globose 
or ovate, finely warty (28-30 diam.). On leaves of Croton procum- 
bens, California.—Cooke, Grevillea, VI., p. 137. 
On leaves of Croton capitatum: Marion, Oct. 20, 1900, IT., 
III. C. monanthogynus: Johnson, May 12, 4649, IL; Jeray, 
Oct. 12, 6282, Oct. 14, 6322: Jackson, Oct. 22, 1945, T., IIL;

JIL., Nox: 1, 2211. Crotonopsis linearis: ‘LaSalle, Sept. 28, 
6226. 
The uredo is Tichobasis crotonis, Cke. The teleutoform 
‘seems to belong to the group separated by Magnus under the 
- generic name of Phragmospora, but it is not easy to make out 
the relation of the spores to the cells of the host in dried 
specimens,
