244 A. Barclay — Descriptive List of the Uredineoe [No. 2, 



winter rest. They are flrmly adherent, and a portion of stalk remains 



on detached sjDores. The spores are rounded at both ends, but little 



constricted at the septum, and with the free end slightly thickened. 



The epispore is studded with fine tubercles. The spores measure 36 /x in 



total length, and 16 at the septum. The upper promycelium emerges 



from the apex of the spore, a little to one side, and the lower from a . ' 



point near the septum. The sporidia measure from 10 x 6 /x to 12 x 7 ju. ^

This is a widely disti-ibuted species and stands in genetic relation- 

 ship with JEcidium TJrticm, Schum, var, Uimalayense, Barclay.* 



Uredojjustules are not very numerous, and are found on the upper 

 surfaces of the leaves : they are inconspicuous, small, brown, and linear 

 or oblong. The spores are elliptical or pyriform, and are beset with 

 prominent tubercles. They are pale yellow, and measure on an average i 

 from 19-8 13-6 //, to 19-2 x 12-8 i>.. 



The teleutospore pustules are minute, circular, and black, mostly i 

 on the upper surfaces of the leaves. The spores are dark brown, firmly 

 adherent, constricted at the septum, thickened at the free end, and ^ 

 usually narrowing towards the stalk. They germinate readily imme- | 

 diately after ripening as well as after a winter rest. They measure on 

 an average 56 in total length and 15 ju. at the septum. The promy- 

 celium of the upper cell emerges from the apex, and that of the lower, 

 from a point near the septum. Four sporidia are formed usually on 

 each promycelium, measuring 12 x 8 /x..
