142 M p^rctle ce, Pk, Hypophyllous; aecidia uniformly distributed over the leaf, short, soon deeply split and recurved; spores elliptical, epispore rather thick, densely tuberculate, 15-18 by 18-24 //; spermogonia numerous, uniformly scattered among the seeidia, honey-yellow. On Psoralea floribunda. JE. leucostictum, B. & C. Hypophyllous; spots very small, scarcely evident, not discolored ; secidia very small, irregularly clustered in little groups, short, many times split; spores subglobose, minutely tuberculate, 11-12 by 12-16 v. On Lespedeza procinnbens. This is named as above in Curtis' catalogue of the Plants of North Carolina and described in Grevillea (III, p. 61) as a variety of M. orobl, Pers. The specific distinction is preferred on account of the difference in size of secidia and spores as well as the appearance of the former. M. orobi, Pers. Hypophyllous; spots usually conspicuous, not thickened, yellow; secidia scattered or collected in orderless groups, small or medium size, short, border many times split and recurved; spores subglobose, usually somewhat angular, epispore rather thick, studded with low obtuse tubercules, often appearing smooth, 18-11 by 21-24 i*; spermogonia few, mostly on the upper side of leaf, in the center of affected spots. On leaves of Amphiearpcea monoica. This is referred to the above named species with some doubt as to the identification. The secidia are collected in more definite groups than are found in typical specimens of the species. JE. grossularce, DC. Hypogenous; spots distinct, swollen, yellow, secidia densely clustered, medium size, edge entire and erect, or often many times split and recurved; spores subglobose, epispore very thin, obscurely roughened, 15-18 ,a. On leaves and fruit of Ribes rotundifolium and cultivated gooseberry. M. epilobii, DC. Amphigenous; secidia scattered rather uniformly over the surfaces of the leaves, sometimes more abundant beneath, short, rather coarsely and deeply split and much recurved; spores subglobose, epispore thin, smooth or nearly so, 15-18 /*; spermogonia honeyyellow, scattered over both surfaces, more numerous above. On Oenothera biennis. M. oenotherce, Pk. Hypophyllous or very sparingly produced above; spots conspicuous, usually purple, scarcely thickened; aecidia crowded in a somewhat definite circle, with a small central vacant area, short, deeply
