Uredospores. Sori hypophyllous, scattered, often confluent, 

 covering the whole leaf-surface, also on the stems, roundish or 

 irregular, covered by the epidermis for some time, then naked, 

 yellow or yellowish-red, fading to whitish: spores ellipsoid to 

 oblong, subangular, strongly and rather densely verruculose, 

 orange, 21 — 35x14 — 21 /*. 



Teleutospores. Sori hypophyllous, subepidermal, scattered, 

 often confluent, forming small, flat, red, then pale-brownish 

 crusts; spores prismatic, up to 100 fi long, 21 — 28 p, wide; 

 epispore hyaline, reaching 35 fi at the summit, but thin
