ON THE UREDINEAE PARASITIC ON TPIE JAPANESE GEAMINEAE. 1 85. 
Uroviyces Alopecuri Seym, (1), I find the following points of difference : — 
1. The uredosori are amphigenous or hypophyllous in our species and 
not epiphyllous as in the American species. 
2. The measurement of our uredospores is a little larger (27 or 28 // 
against 24 //). 
3. Though the teleutosori are written as epiphyllous, they are mostly 
hypophyllous in our species and also most commonly formed at the basal 
part of the sheath. 
Although the essential characters of the uredospores and teleutospores 
are practically the same, the above mentioned differences in character being 
constant, I think it better to treat our plant as a variety of the American 
Uromyccs Alopecuri.
