In Obs. Myc. I, p. 17, Persoon described ZTredo appendicu- 

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

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

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

 the name Uronn/ces phaseoli is frequently used.

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
