 April to June. 



Biology. — The sori occur upon pale spots on the leaves and stems ; 

 on the latter, they cause elongated distortions. This species was at 

 one time considered to be the teleutospores of ALcidiuni ficario', until 

 Schroter (Cohn's " Beilrage," vol. ii. pt. iii. p. 63) worked out the life- 

 history of the Ranitnctihis ^-Ecidia. 



Uromyces scillarum. (Grev.) 



Teleutospores — Sori amphigenous, brown, arranged more or less 

 concentrically, sometimes irregularly, becoming confluent, 

 especially in the centre of the larger groups, at first covered 

 with the cuticle. Spores roundish, ovate, or elliptical, with a 

 uniformly thick, smooth, brown epispore, apex rounded or 

 flattened, 20-30 x 15-20/A. Pedicels short, slender, deciduous.
