Uredospores. Sori amphigenous, but mostly hypophyllous, 

 scattered, minute, round, sometimes confluent, surrounded by 

 the cleft epidermis, soon naked, pulverulent, cinnamon ; spores 

 globose to ellipsoid, with short blunt and rather distant spines, 

 brownish, 17 — 25x16 — 23 yu, ; epispore '21 — 3 fi thick, with 

 2 — 5 germ-pores. 



Teleutospores. Sori similar, but darker in colour; spores 

 globose to obovate, often with a low flat pore-cap at the apex, 

 which is not thickened, beset with minute warts and ridges 

 which are often arranged in undulating longitudinal lines, 

 brown, 17 — 25 x 14 — 21 fi; pedicels short, hyaline, deciduous.
