“130 PUCCINIA 
pale clear-brown, 45—60 x 20—25 4; pedicels brownish, persis- 
tent, thick, about as long as the spore or longer; no mesospores 
were seen, but some irregular spores.

The greyish tinge mentioned by Plowright seems to be due to germ- ‘ 
tubes issuing from the spores of this Leptopuccinia. This species is 
decidedly different from the American forms with which it is united by 
Sydow ; there are no spots, the colour of the spore is paler, the apex not 
so much thickened, and the sori are not confined to the lower leaf-surface. 
Many spores were observed bifid at the summit, but not owing to germi- 
nation, which had not taken place in them.
