In Schweinitz's Syn. Fung. Car. (No. 503) this species is 

 named Pmcinia Hedysari paniculati, but in his N. Am. Fungi 

 (p. 297, No. 2947), subsequently published, the name is Pltray- 

 midium Hedysari. The plant called Hedysarum panicidatmn 

 by Schweinitz is now transferred to the genus Desmodium, with 

 other species upon which the fungus also occurs. In March, 

 1878 (Hedw. XVII., p. 39), Cooke described the same plant 

 under the name Uromyc.es Desmodii; and Thiimen, at the same 

 time (Bull. Torr. Bot. Club, VI, p. 215), also bestowed the bit- 

 ter name upon the species, with a still fuller and better des- 

 cription? Farlow (Ellis N. Am. Fungi, No. 246 [1879]) 

 restored the original specific name, and wrote Uromt/ces Hedij- 

 sari-paniculati (Schw.). 



U. lespedezae, (Schw.) Peck. 



II., III. Hypogenous and often also sparingly epigenous; 

 spots yellowish, very small; sori small, scattered, at first cov- 

 ered by the epidermis, lead-colored, soon exposed, black, sur- 

 rounded by the ruptured remains of the epidermis. Uredo sori 

 light brown. Both kinds of sori often surrounded by curved 

 paraphyses. II. Spores pale, subglobose, 16-18 by 18-21 /it; 

 epispore rather obscurely echinulate. III. Spores rounded 

 to oblong, with the rounded, obtuse, or pointed apex strongly 

 thickened, frequently forming one third of the length of the 

 spore, blackish brown, smooth, 12-15 by 21-27 ^; pedicel 

 hyaline, rather broad, about 36 /* long. Paraphyses hyaline, 

 of nearly uniform diameter, rounded apex, 6-9 ^ broad.
