114 a case as the present for disregarding a well established and appropriate rule. In the accessible descriptions nothing is said of the tuberculate surface of the teleutospore. P . heterospora, B. & C. III. Spots purple, definite; sori hypogenous, small, densely and definitely clustered, 'soon naked, epidermis inconspicuous; spores subglobose or rarely elongated, mostly single celled but frequently septate in any direction; epispore smooth, gradually thickened toward the apex, diameter 18-27 <>-\ pedicel hyaline, slender, diminishing below, about three to five times the length of the spore. On Sida spinosa; Union, Sept. 17, 1883, 5083 Coll. T. S. Earle. This is Uromyces pulcherrima, B. & C. (Grev. I l l , p. 56, Dec. [1874;]) also 17. Thwaitesii, B. & Br. (Journ. Linn. Soc. XIV., p. 92, [1875.1) The original description is by Berkeley and Curtis, (Jour. Linn. Soc. X, p. 356, [1869.]) See A. B. Seymour, Botanical Gazette, 1884, p. 351. The species is properly a Puccinia, since the septate cells though usually less in number than the simple ones, are numerous and normal in character—evidently the highest development of the plant. P . nolitangeris, Cda. Hypophyllous. II and III. Sori minute, scattered, uredosori yellowish; teleutosori brown; uredospores subglobose, obscurely echinulate, diameter 16-19 //; teleutospores elliptical to oval but irregular, rounded at both ends and slightly constricted, with a prominent hyaline apiculus, 15-18 by 25-33 ,u; pedicels hyaline, very fragile and deciduous, apparently about as long as the spores. On leaves of Impatiens fulva and I. pallida. This species has now been found for four successive years in the "Lower Park" at Deer Park, La Salle Co., though diligent search fails to discover it in any of the similar localities in that region, nor has it been found elsewhere in the State. P . amorpJue, Curt. II. Sori usually epiphyllous, small, few, clustered, surrounded by numerous, closely packed, clavate, incurved, brown paraphyses; spores ovate or oval, minutely echinulate, 12-15 by 18-21 /A III. Amphigenous, sori small, scattered or above clustered and circinate; paraphyses as in I I . ; teleutospores much constricted, cells globose, enveloped by a thick, hyaline, readily separable coat, without latter 24-30 by 42-45 /*; pedicels hyaline, fragile. On leaves of Amorpha fruticosta and A. canescens. This is Uropyxis amorphoe, Schroeter, but aside from the peculiar coating of the teleutospore there is nothing to separate the species from Puccinia. The uredoform would have been considered a good
