ON GRAMINEA 281 
On leaves (living or fading) of Brachypodium pinnatum, 
B. silvaticum. Not uncommon. July—November, teleuto- 
spores not before September. (Fig. 212.) 
Both Plowright and Fischer mention that, mixed with the uredospores, 
are numerous hyaline capitate paraphyses ; Sydows’ Monographia omits 
all mention of these. The specimens which I have seen show them always 
in great numbers. ’ 
Often the pedicel of the teleutospores is almost non-existent, and the 
basal cell-wall is strongly thickened. The upper margin of the teleuto- 
spore is often undulated ; occasionally one is met with having three 
cells. An ecidium, though often suggested, has not yet been discovered 
for this species.
