Uromyces Leguminosae. 95 



II. Uredospores golden-brown, elliptic to ovoid, echinulate, relatively 



thick-walled, with three distinct equatorial germ-pores on one face, 

 25-35 x 20-22 /*, average 27 x 20 p. 



III. Teleutospores intermixed with uredospores, very sparse, ruddy- 

 brown, thick-walled, smooth, ellipsoid to obovoid, slightly 

 thickened at apex, with hyaline apiculus and showing germ-pore, 

 25-28 x 18-21 //, average 26 x 19 p ; pedicel persistent, hyaline, 

 elongated, up to 35 // long.

Victoria Kergunyah, Dec., 1903, II., III. (Robinson). Frankston, 



January and August, 1904, II. (Robinson). 



The teleutospores were exceedingly rare, and somewhat resembled the 

 uredospores, but slightly smaller, with ruddy smooth epispore and hyaline 

 apiculus. 



This species persists all the year round. 

 Darluca filum Cast., very prevalent on uredosori.

O. Spermogonia brown at first, becoming shining black, numerous, 

 small, blister like, seated in centre of swollen, brownish, scattered, 

 discoid, amphigenous tubercles, varying in size from 1 to 4 mm. 



II., III. Sori surrounding spermogonia or alone, ruddy brown to dark- 

 brown, round or elongated, crowded, often confluent, compact, 

 raised, girt by the ruptured epidermis, which bursts irregularly. 



II. Uredospores golden yellow to golden brown, oval to ellipsoid, 



rounded at apex or bluntly pointed and slightly thickened, densely 

 warted, and warts arranged in regular longitudinal lines, with 

 distinct equatorial germ pores, 3-4 on one face, and even reaching 

 to 6, 35-54 x 16-25 ^, average 38 x 22 /z, with elongated 

 and hyaline pedicel. 



III. Teleutospores at first intermixed with uredospores, lemon yellow, 

 and sometimes almost colorless towards base, fusiform to wedge- 

 shaped, thickened at apex, and bearing finger-like erect or divari- 

 cate processes, sometimes a single process, or bifid, or several, 

 60-70 X 14-20 /z, but may even reach a length of 86 p ; pedicels 

 long, persistent, hyaline ; paraphyses intermixed with teleuto- 

 spores or with uredospores accompanied by teleutospores, elongated, 

 variously shaped, but generally somewhat cylindrical, thickened 

 and rounded at apex, and tapering sometimes into a slender 

 filament at base, 70-93 X 6-10 p.
