ON THE SYNONYMY OF SOME SPECIES OF UREDINEiE. 

 By W. G. Farlow. 



Presented Feb. 13, 1878. 



In the " Bulletin of the Bussey Institution," Vol. II. No. 20, refer- 

 ence was made to two species of Uromijces ; one found on Spartina 

 stricta, and the other on Brizopyrum spicatiim. In the paper above 

 named, the occurrence of the two species in America was considered in 

 detail, but their identity with European forms was barely noticed. The 

 species on Spartina^ which was refei'red to Uromyces Jtnici, Scliw., was 

 said to agree with the Puccinia Juncl of Chevalier's " Flore de Paris." 

 The latter species seems to be the Uromyces Junci of Tulasne men- 

 tioned in " Annales des Sciences Naturelles " 4 ser., torn. 2, which is 

 founded on Puccinia Jimci, Desm. The date of the publication of 

 Schweinitz's Puccinia Junci is 1831, and the species of Desmazieres 

 appeared some years later. The species on Bryzopyrum appears to be 

 the same form as that referred by Schroeter in " Beitrage zur Biologie 

 der Pflanzen," Vol. I. pt. 3, p. 7, to Uromyces Dactylidis, Otth, in 

 which he includes Uromyces graminum, Cooke. 



In the same article in the Bulletin, Peronospora ohliqua, Cooke, 

 growing on Rumex ci-ispus, was referred to Ramularia macrospora, 

 Fres. There has lately appeared, in a recent number of the " Natur- 

 aliste Canadien," a list of fungi found near Quebec, determined by Von 

 ThUm.en. Amongst other species is quoted Ramularia ohovata, Fuckel 

 on Rumex. This probably refers to the same fungus as that mentioned 

 in the " Bussey Bulletin." If, as is probable, R. macrospora, Fres., and 

 R. ohovata, Fuckel, should be united, the name of Fresenius claims 

 priority. 



An interesting Puccinia and accompanying Aecidium found by Mr. 

 Cleveland on Malvastrum marruhioides at San Die<TO, Cal., was 

 referred to Puccinia Malvacearum, Mont., with considerable doubt, as 

 a variety differing from the type in the shape and color of the spores.
