ee flask-shaped, immersed, the surrounding paraphyses 
alone protruding, honey-coloured. 
I. Aecidia at first immersed, becoming erumpent and cupulate, or 
cylindrical. Peridia hyaline, less frequently coloured, margins erect or 
revolute, dentate, lacerate, or seldom entire. Aecidiospores catenulate, 
commonly polygonal, less frequently elliptical; epispore usually ver- 
ruculose, hyaline, seldom tinted, with numerous scattered din indistinct 
germ-pores. 
П. Uredosori without peridia, commonly pulverulent, with or without 
paraphyses, and usually surrounded by the ruptured epidermis. Uredo- 
spores from globose to obovate, borne singly at the apices of pedicels ; 
epispore commonly echinulate, less frequently verrucose, coloured, with 
one or several evident germ-pores which may be scattered or equatorially 
arranged. 
III. Teleutosori — less frequently pulverulent, naked or long 
covered. Teleutospores unicellular, borne singly on distinct pedicels ; 627
