in thickness. The wall is furnished 

 with 4-6 conspicuous germ-pores at the 

 equatorial region. (Fig. 1.) 



"When sown in a drop culture, the 

 spores germinate with 2 or 3 long 

 slender germ-tubes about 3/x in diameter 

 within 20 hours. (Fig. 2.) 



In winter, many whitish sori are 

 produced on both sides of a phyllod, 

 this time without producing any bulla- 

 tion as in the case of the uredo-sori. 



The whitish sori, 

 under a magnifying glass, 

 are hemispherical and vel- 

 vety in appearance. They 

 are formed of the teleuto- 

 spores and their pedicels 

 densely bound together. 



The teleutospores are 

 hyaline and very thin- 

 walled, quite different 

 from those of the ordinary 

 species of Uromyces. They 

 are smooth, elliptical, 

 obovate or oblong to 

 elongated oblong, measur- 

 ing 36 to 51 p in length 

 and 19 to 27 ix in breadth 

 and provided with hyaline 

 long persistent pedicel 



(60-130// x 5-9/y.). 

 (Fig. 3.) When sown in 

 water, those spores pro- 

 duce a proniycelium from 

 the tip, on which sporidia
