On Epilobium hirsutum, montanum, tetragoniwi. 



Biology. — The mycelium of the jecidiospores 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 tecidiospores sown 

 on seedlings of E. hifsi/ti/jn gave rise to aecidiospores in seventeen 

 days. 



Puccinia violse. (Schum.) 



^cidiospores — 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 T0-18/X. 



Uredospores — Sori brown, small, roundish, scattered, soon naked. 

 Spores roundish or elliptical, brown, echinulate, 20-26^1 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 

 i5-20yu,. Pedicels long, deciduous.
