Hcmiu romyccs. 1 3 5 



Biology. — The mycelium of the teleutospores permeates the 

 whole plant. The foliage of the affected plants is altered by its 

 presence, being shorter, broader, and thicker ; moreover, they seldom 

 blossom. The sori are scattered over the whole plant. Winter con- 

 siders this species to belong to Hemiuromyces, Schroter that it is 

 without uredospores. It is doubtfully British. 



Uromyces anthyllidis. (Grev.) 



Uredospores — Sori roundish, chestnut-brown. Spores subglobose,
