In Obs. Myc. I, p. 17, Persoon described Uredo <ii>i><'n<iicn- 

 lata. and in Syn. Fung. pp. 221-222, repeated it with var. plm- 

 seoli, and two other varieties. The latter have been referred to 

 other species, leaving the original name for this form; but 

 the name Uromyces pltaseoli is frequently used.

I. Infected leaves somewhat involute or revolute: peridia 

 irregularly scattered over both surfaces of the leaf, minute, 

 short, roundish or slightly elongated, with a whitish, spreading 

 or somewhat recurved, irregularly lacerated border; spores pale, 

 globose-angular, 15 , in diameter. II. Spots red-purple, 

 indefinite; sori epigenous, roundish, soon naked, brown; spores 

 subglobose. minutely echinulate, brown, 15-18 by 16-24 /*. 

 III. Spots same; sori roundish or oblong, epigenous and soon 

 naked, or cauline and long covered by the epidermis, blackish: 

 spores oval, elliptical, or oblong, strongly thickened at the 

 apex, broadly rounded or variously pointed, dark brown. 16-18 

 by 24-80 /*; pedicels about 1^ times the length of the spore, 

 often broad, tinted, especially close to the spore.

The aecidia occur on the cauline leaves, affecting all alike, 

 but sparingly on the radical leaves: the uredo- and teleutoforms 

 are mostly confined to the radical leaves. The pedicels of the 

 uredo spores are frequently persistent.
