 Described by Underwood as follows : 



"II, III. Amphigenous; sori very small, short, very numerous 

 but irregularly scattered, remaining long enclosed in the tough epi- 

 dermis of the host, at length rupturing by a narrow slit; uredo 

 spores large, broadly oval, 35 x 30 /x, scarcely echinulate, the epi- 

 spore or medium thickness, pale rusty brown ; teleutospores variable, 

 usually short, irregularly oblong, often somewhat constricted at the 

 septum, averaging 25 x 40 n, the cells often irregularly angled, the
