Persoon de8c'ril)ed (Syn. Fung. p. 219) Vredo piistuhita 

 var. rplloljii. and DeCandolle wrote Uredo epilohii (Flora Franc, 

 IF. \\. 226). and Fuckel described the teleutoform and referred 

 tlie uredo to same species. The name Uredo piistiilata. Pers.. 

 has been used for various species. 



M. crotonis, Rurrill. 



II.. III. Amphigenous. ITredosori scattered, rather prom- 

 inent, circular, cinnamon-colored; uredospores obovate, sharply 

 echinulate. produced on pedicels, 15-21 by 18-27 i*-; 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 ,u. 



Trichoham crotonis, Cooke. Amphigenous; sori minute, subrotund, 

 surrounded by the ruptured epidermis, fuscous: pseudospores globose

The uredo is Trichol)asis crotonis, Cke. The teleutoform 

 seems to Ijelong to the group separated by Magnus under the 

 generic name of UJir(if/)uosj/or((. but it is not easy to make out 

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

 specimens.
