0. Spermogones amphigenous, scattered, sparse, associated with the 
uredosori. 
II. Uredosori amphigenous and caulicolous, scattered, or more com- 
monly in small orbicular or elliptical groups of 3-5 sori, 1-3 mm. long, 
seated on discoloured spots, orbicular, 0-25-1 mm. diam., on stems elliptical, 
confluent, and up to 5 mm. long, bullate, immersed, partly covered by the 
epidermis, yellow, opening by an irregular apical pore, encircled by a single 
layer of thick-walled chestnut-brown paraphyses. Spores elliptical or 
obovate, 30-42 x 20-24 mmm. ; epispore hyaline, densely and finely verru- 
coloured spots, bullate, dark chestnut-brown, orbicular or irregular, up to 
mm. diam., compact, long covered by the epidermis; encircled by a 
single layer of chestnut-brown clavate paraphyses. Spores elliptical or 
subclavate, 50-60 х 24-31 mmm.; apex rounded or bluntly acuminate, 
thickened up to 6mmm., base attenuate, frequently rounded, lower cell 
slightly narrower; not or slightly constricted at the septum; epispore 
smooth, pallid chestnut-brown, 1-5-2 mmm. thick, cell-contents granular ; 
pedicel persistent, tinted brown, up to 38 x 8 mmm. ; germ-pore of the 
upper cell apical or slightly oblique, conspicuous, basal pore immediately 
beneath the septum, conspicuous.
