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

 named Puccinia Hedysari paniculati. but in his N. Am. Fungi 

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

 midiitm Hedysari. The plant called Hedysarum paniculatam 

 by Schweinitz is now transferred to the genus Desmodium, with 

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

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

 under the name JJromyces Desniodii; and Thiimen, at the same 

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

 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 Uromyces Hedy- 

 sari-patiiciihifi ( Schw. ) .
