Puccinia Rubiaceae. 



TJredospores globose to shortly elliptical or obovate, golden- 

 brown, finely echinulate, one to two germ-pores on one face, 

 25-29 x 22-25 /u, or 25-27 /* diam. 



III. Teleutosori on stems, dark-brown to black, elongated, bullate, 

 soon naked, compact, 2 mm. long or more. 



Teleutospores narrowly clavate to oblong, brown, constricted at 

 septum, thickened at apex (9-10 ^), and rounded or bluntly pointed, 

 or may be truncate, lower cell generally attenuated towards base 

 and paler in colour, 32-54 x 16-21 fi, average 48-16 ^u; pedicel 

 yellowish, persistent, up to 48 jj. long. 

 X. Mesospores occasional, similarly coloured to teleutospores, somewhat 



fusiform, with pointed and thickened apex, 28-32 X 12-13 /^.

The examination of specimens of P. punctata Link, on species of Asperula 

 from Exsicc. Sydow Ured. 465, 466, showed that the two were distinct. In 

 P. oligantha the uredospores are broader, and while the teleutospores 

 average only about 16-18 p broad, in P. punctata they are about 20-22 //. 

 In the latter too the apex is much thicker, reaching up to 16 jw. The 

 species closely resembles P. asperulae odoratae Wurth, but aecidia are 

 present on the latter, and the teleutospores are only thickened at the apex 

 to the extent of 7 ^u.

I. Pustulate, deforming the leaves ; pseudoperidia immersed. 

 Aecidiospores orange, subangular. 



III. Teleutosori hypophyllous, on orbicular brownish to yellowish spots, 

 solitary or a few together, round or elliptic, compact, reddish- 

 brown, girt or partially covered by the ruptured epidermis, up to 

 2 mm. long. 



Teleutospores golden-biown, oblong to oblong clavate, constricted 

 at septum, smooth, 35-54 x 14-20 /it; upper cell rounded or 

 pointed and thickened at apex (up to 11 ^u), about equal in length 

 to lower ; lower cell usually tapering towards base or sometimes 

 rounded ; pedicel hyaline, persistent, 80 p or more long and 6-7 /i 

 broad.
