 prominent, closed, collected in little clusters. Pers. Syn. Fung. p. 219. 



Melampsora epilobii, Fckl. F. rh. 300. I., II. I. Fungus stylosporif- 

 erus. Uredo Epilobii DC. Fl. Fr. II. p. 226. On leaves of Epilobium

On Epilobitnn coloratum: JoDaviess, Sept. 20, 6019, II. 

 Persoon described (Syn. Fung. p. 219) Uredo pustalata 

 var. <'i>ilobii, 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. 



II., III. 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 ,u diam.). On leaves of Croton procum- 

 bens, California. Cooke, Grevillea, VI., p. 137. 



On leaves of Croton capitatum: Marion, Oct. 20, 1900, II., 



III. C. monanthogynus: Johnson, May 12, 4649, II. ; Jersey, 

 Oct. 12, 6282, Oct.' 14, 6322; Jackson, Oct. 22, 1945, II., III.: 

 Nov. 5, 2266; Union, Oct. 25, 2010, II, III., Oct. 31, 2157, II.,

The uredo is Trichobasis crotonis, Cke. The teleutoform 

 seems to belong to the group separated by Magnus under the 

 generic name of Phragmospom, but it is not easy to make out 

 the relation of the spores to the cells of the host in dried 

 specimens.
