In Obs. Mye. J, p. 17, Persoon described Uredo appendicu- 
lata, and in Syn. Fung. pp. 221-222, repeated it with var. pha- 
seoli, and two other varieties. The latter have been referred to 
other species, leaving the original name for this form; but 
the name Uromyces phaseoli is frequently used. 
U. cenothere, Burrill. 
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, 
elobose-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 p. 
IIL. 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 24-30 »; pedicels about 14 times the length of the spore, 
often broad, tinted, especially close to the spore.

The ecidia 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.
