Uredo Fotentillarum, D. C. Spots yellowish; sori subrotund or oval, bullate, aggregate, open, confluent; spores sub-globose, sub-coherent, orange. On various Rosacea; (Westbrook E. C. B. New York, TV. W. D.) (Schweinitz, Syn. Car. No. 461. Fung. No. 2834. Lea, Plants of Cincinnati. p. 71. Ravenel, Fung. Car. Exsic. ii. No. 97.) Uredo Filicum, Desm. Spots yellowish, sori subrotund, bullate, scattered and agregate, on the under surface ; epidermis at length bursting; spores sub- globose, yellow. On Ferns. (Scarboro', E. C. B.) r (Schweinitz, Fung. Am. Bor. No. 2836. Ravenel, Fung. Car. Exsic. iv. No. 97.) I have received Uredo solidaginis Schw. from New York, and Newport, Rhode Island, but not at present from Maine.* » Uromtces, Lev. Spores unilocular, attached permanently to a decided peduncle of greater or less length. Uromyces apiculosa, Lev. Spots yellow or brown. Sori sub-rotund, scattered, surrounded by the ruptured epider- mis ; spores ovoid, brown, shortly pedunculate. On leaves of various plants, (Peak's Island, E. C. B.) ( Uredo apiculosum. Schweinitz, Syn. Car. No. 478. Fung. Am. Bor. No. 2844.) Uromyces triquetra, Cooke. Spots claret-colored ; Sori small, scattered, hypogenous, sur- rounded by the remains of the ruptured epidermis. Spores angular, often three sided. On leaves of Hypericum, (Scarboro, Westbrook, E. C. BJ Whether this is the same as the species described by Schweinitz under the name of Uredo Hyperici is somewhat un- certain, since his specimens are recorded as occurring on the stems, forming elevated bullate sori, and the present is confined to the leaves, and the sori ar
