III. Teleutospores. Sori linear 1 — 3 mm. long, solitary 

 or gregarious; spores from broadly-oblong to nearly orbic- 

 ular, constricted ; septum scarcely visible, stipe stout, 

 hyaline, as long as the spore, deciduous, pi 36 — 42 X 22 — 28.

Uromyces Brodieae. 



I. Hymenium. iEcidium Brodieae. EH- & Hk. Amphige- 

 nous, on pale yellowish spots, 2 — 4 mm. in diameter ; on 

 which are crowded in clusters, 6 — 10 shallow cup-shaped 

 peridia with orange - yellow disk and narrow lacerated 

 border. 



II. Stylospores. Uncertain. 



III. Teleutospores. Spots obliterated; soriampbigenous, 

 scattered, oblong, about 1 mm. in diameter, sometimes sub- 

 confluent in elongated patches, dark umber-brown; spores 

 obovate; epispore scarcely thickened above; pedicel equal in 

 length to the spore, f-i 20—28 X 13—20.

Nearly allied to TJ. Zygadeni, Pk., but the spores are small- 

 er and more delicate. The peridia of the ascidiuin are more 

 distinctly clustered, and not mixed with teleutospores; both 

 seem to be distinct from TJ. Liliacearum, Schw. 



Uromyces chorizanthis. 



I. Hymenium. Unknown. 



II. Stylospores. Globose, granular, pale brown. 



III. Teleutospores. Sori elliptic, convex, dark brown, I — 1 

 mm., spores obovate; epispore strongly thickened above ; 

 pedicels hyaline, stout, three times as long as the spore. 

 Spore f.1 20—30 X 19—22. 



On stems and leaves of Chorizanthe pungens. San Fran- 

 cisco, July. 2641. 



Differs from TJ. Polygoni, Fckl. in its larger, darker and 

 more prominent sori.
