 Uredo notabilis Ludw. 



O. Spermogonia minute, punctiform, black, in swollen tubercles often 

 intermixed with uredospores and teleutospores. 



Spermatia hyaline, ovate or ellipsoid, on elongated basidia, 4 x 

 2-3 /i. 



II. Uredosori on both surfaces of phyllodes, on branches and pods, 



ochraceous to yellowish-brown, seated on a distorted inflated gall. 

 Uredospores ellipsoid to oblong, bright yellow when fresh, 

 becoming yellowish-brown, on elongated hyaline pedicels, with 

 3-5 equatorial germ-pores on one face; epispore thick (3 p), reticu- 

 late, 30-45 x 18-28 //. 



III. Teleutosori on branches, phyllodes and legumes, forming large, 

 swollen, distorted galls, chocolate-brown, at length very powdery. 



Teleutospores intermixed with uredospores at first, in clusters 

 of three (rarely two or four), sub-globose to depressed globose, 

 yellowish-brown, densely covered with warts arranged in lines, 

 slightly thickened at apex, with germ-pore beneath, 16-23 x 

 21-26 p.

 The ochraceous uredosori are generally distinct from the chocolate-brown 

 teleutosori, but sometimes the two kinds of spores are found intermixed. 



The arrangement of the teleutospores is generally the same as in 

 U. tepperianum, but the dense covering of warty spines instead of distinct 

 striae differentiates them at once and the height of the spore is greater. The 

 spermogonia are found in association with both uredospores and teleuto- 

 spores. 



The uredospores closely resemble in size and shape those of Uromyces 

 phyllodwrum, but the surface markings serve to distinguish them. In the
