III. UROMYCES ON CLADRASTIS. 



BY 



S. Eusano. 



Uromyces shikokianus Knsano n. sp. 



Teleutosori hypophyllous, isolate, indefinitely scattered, small, punc- 

 tiform, pulverulent, black, paraphyses numerous, nearly solid, crooked, pale 

 yellow ; uredospores very few, intermixed with the teleutospores, obovate 

 or broadly elliptical, wall rather thin, verrucose, yellowish brown, 25x20^; 

 teleutospores oblong or fusiform, but mostly pyriform, with pointed apex, 

 wall dotted with large knobs, grayish brown to chestnut brown, thickened 

 conically at the apex, 30-40x16-18 //; pedicel thin-walled, fragile, hyaline, 

 nearly as long as the spore or somewhat longer. 



On the leaves of Cladrastis shikokiana Makino. Oct. 1904, Mt. 

 Yanaze in Prov. Tosa (T. Yoshinaga). 



The material examined was somewhat incomplete, so that it is 

 unknown whether uredospores form a distinct sorus or are found in the 

 same sorus as teleutospores. 



Uromyces Cladrastidis Kusano n. sp. 



Teleutosori hypophyllous, isolate, indefinitely scattered, punctiform, pul- 

 verulent, black, paraphyses numerous, nearly solid, crooked, pale yellow ; 

 spores globose, oval or rarely elliptical, rounded at the lower end, obtusely 

 or acutely pointed at the apex, wall finely verrucose, chestnut brown, 

 slightly thickened at the apex, 20-27 x 17-20 /x ; pedicel thin-walled, fragile, 

 hyaline, 50 /*. 



On the leaves of Cladrastis shikokiana Makino. Oct. 27. 1900, Chi- 

 chibu in Prov. Musashi (Y. Yabe). 



This species is closely allied to U. shikokianus, but differs in the form 

 of teleutospores and the sculpture of their surface.
