brown, and generally having a purple margin. Both aecidiospores and 

 teleutospores are produced from the same mycelium, as is the case 

 with the Chilian species, Puccinia berberidis. 



Uromyces scrophularise. (D. C.) 



yEcidiospores — Pseudoperidia on yellowish spots, in roundish cir- 

 cinate clusters, generally hypophyllous, with rather prominent, 

 yellowish-white, erect or sometimes inverted, entire edges. 

 Spores rounded, polygonal, finely verrucose, 17-30/A in 

 diameter. 



Teleutospores — Sori frequently intermingled with the accompanying 

 secidia, circinate, confluent or following the venation, small, 

 round or elliptical. Spores round, obovate or oblong, or 

 subpyriform, with much-thickened, often conically attenuated 

 summits, chestnut-brown, smooth, 20-35 X io-20/x. Pedicels 

 rather long, deciduous.

Biology. — The mycelium causes considerable distortions of the 

 stem and petioles ; the spots are yellowish, usually surrounded by a 

 purplish margin. In this species the same mycelium which produces 

 the lecidiospores also gives rise to the teleutospores.
