On L£pilobium hirsutum, montanum, tetragonum. 
BrioLoGy.—The mycelium of the zcidiospores is diffused through 
the greater part of the affected plant, but whether it be truly perennial 
I cannot say. The mycelium of the uredospores and teleutospores is 
strictly localized. I found in June, 1882, that the ecidiospores sown 
on seedlings of ,Z. hirsutum gave rise to ecidiospores in seventeen 
days. 
Puccinia viole. (Schum.) 
Acidtospores—Pseudoperidia on the leaves in circular concave 
patches, often causing much distortion on the stems, flat, with 
white torn edges. Spores subglobose, finely verrucose, orange- 
yellow, 16-24 X to-18p. 
Uvredospores—Sori brown, small, roundish, scattered, soon naked. 
Spores roundish or elliptical, brown, echinulate, 20-26 in 
diameter. 
Teleutospores—Sori black, roundish, small, pulverulent. Spores 
elliptical or oblong, slightly attenuated at the base, with an 
apical thickening, constriction almost absent, brown, 20-35 X 
15~20u. Pedicels long, deciduous.
