BRITISH SPECIES OF UROMYCES. 
tion has been drawn, and the fact is beyond dispute that an 
Uromyces is found, late in the year, after the sEcidium is gone, on 
the stems of the Nettle. We are not, however, prepared to accept 
the evidence as complete and satisfactory, for such species in which 
the Alcidium is said to be found on a foster plant of a different 
genus, and order, to that of the Uromyces. 
In the following notes the continental method is adhered to of 
noting the three stages in the order of development, as — 
I. Hymenium, or ALcidium. 
II. Stylospores, or Uredo. 
III. Teleutospores, or Uromyces ^
