Lcptopitccinia. 2 i 7 



described by Link (" Sp. Plant.," vol. vi. pt. ii. p. 74), which has very 

 short pedicels, and occurred on Tussilago alpina and Centaurea 

 alpina. It may be Fuckel's P. cirsii. 



Puccinia buxi. D. C. 



Teleutospores — Sori chestnut-brown, compact, hemispherical, 

 cushion-shaped, soon naked, amphigenous. Spores oblong or 

 elliptical, deeply constricted, upper cell obovate, apex rather 

 thickened, lower cell attenuated below, cuneiform, generally 

 longer than the upper, brown, smooth, 55-90 X 25-35/i,. 

 Pedicels very long.

Biology. — The spores hdve a tendency to fall in halves at the 

 septum. The sori occur on both surfaces of the leaves, and are accom- 

 panied by slight yellowish or brown discolorations. Schroter was 

 unable to get this fungus to reproduce itself by applying the promy- 

 celial spores to the foliage of box plants. It seems to me probable 

 that the germ-tubes enter the leaves and give rise to a mycelium 

 which remains in a quiescent state until the following spring. This, 

 however, is only an opinion, and has not been proved by experimental 

 culture. 



Puccinia annularis. (Strauss). 



Teleulospores — Sori small, compact, round, confluent in subrotund 

 patches, hypogenous, at first greyish brown, then cinnamon, 

 at length brown from the rupture of the epidermis. Spores 

 oblong, slightly constricted in the middle, summits rather 

 strongly thickened, rounded, rarely truncate, sometimes attenu-
