124 uredospores subglobose or oval, sharply echinulate, wall thick, 18-24 by 21--7 fi; teleutospores clavate, oblong or elliptical, abruptly and rather deeply constricted; apex thickened and mostly narrowed to a rounded point, lower segment usually longer and narrowed to the pedicel, surface smooth, 12-21 by 39-50 /*; pedicel hyaline, usually less than the length of the spore, but sometimes longer. On Aletris farinosa: Millers, Indiana, near the Illinois line, July 4th, 1882. Coll. E. J. Hill. It probably occurs in Illinois.

P . smilacis, Schw. II and III. Hypogenous; spots small, numerous, brick-red; sori scattered or irregularly circinate, punctiform or elongated, surrounded by the raptured epidermis and by a row of short, club-shaped paraphyses. II. Uredospores oval, slightly echinulate, pale, 21-27 //, on fragile pedicels. HI. Teleutospores broadly elliptical, conspicuously constricted, upper segment considerably rounded or obtusely pointed, often narrowing below to the pedicel, dark colored, smooth, 21 by 35-42 y; pedicel thick, tinted, as long as the lower segment. On leaves of Smilax hispida.

P . caricis, (Schum.) Eebent. II and III. Hypogenous; sori more or less elongated, variable, scattered, often very numerous and conspicuous, the ruptured epidermis ragged and long adherent; uredosori cinnamon-brown, teleutosori black; uredospores globose, subglobose or sometimes elongated, conspicuously but not sharply echinulate, 18-24 by 21-27 y; teleutospores cuneate, little constricted, much thickened, obtusely rounded or almost truncate above and narrowed to the pedicel, smooth, 15-20 by 33-45 y; pedicel hyaline or nearly so, one-half to once the length of the spore. On Carex sps. and Dulichiwm spathaceum. Uredo Caricis, Schum. (Enum. Plant. Ssell, II. [1803] p. 231), P . caricina, DC. (Fl. Franc. VI. [1815] p. 60). On Dulichium spathaceum the uredospores are smaller and often elliptical to oblong, 12-15 by 15-21 y; the teleutospores are variable, more often truncate.

P . obtecta, Peck. II and HI. Amphigenous; sori scattered or irregularly clustered, often crowded, oblong, or more or less circular, long covered by the epidermis which at length becomes simply cracked or raggedly torn; uredospores elliptical or obovate-oblong, wall rather thick, minutely echinulate, 15-20 by 21-30 i±\ teleutospores elliptical, somewhat constricted, apex thickened, obtusely rounded or variously produced and
