III. Teleutosori hypophyllous, gregarious, on orbicular spots, forming 

 rings which are at length confluent, rather compact, dark-brown. 



Teleutospores elliptic, constricted at septum, rounded at ends or 

 occasionally flattened, smooth, brown, 30-34 x 17-25 p, average 

 32 X 22 p ; occasionally 3-celled, then reaching to a length of 

 49 f-i ; pedicel hyaline, deciduous or persistent, sometimes origin- 

 ating laterally, rather long. 



X. Mesospores occasional, just resembling a teleutospore, but without 

 the septum, elliptic, with hyaline pedicel, 29-31 x 22-25 p.

 (Bailey 1G ). 



Mr. Bailey has kindly sent me some excellent material from his herbarium 

 and the teleutospores have been carefully measured. In the original 

 description the size is given as 20-22 x 16 /*, but probably 30-32 p was in- 

 tended for the length. 



Sometimes both upper and lower cell have an oblique division. 



It differs from P. alyxiae Cooke and Mass., in which the spores are much 

 larger and thickened at the apex.

0. Spermogonia dark honey-coloured, disposed in clusters on yellowish 



spots, or intermixed with aecidia on the same surface of the leaf, 

 usually the upper. 



1. Aecidia scattered 01^ more often circularly arranged on reddish, 



slightly swollen indeterminate spots, mostly on upper surface of 

 leaves and on petioles ; pseudoperidia with white margin, torn, 

 slightly recurved and soon falling away, average ^rnm. diam.; 

 isolated peridial cells, generally short and stout, less commonly 

 elongated oblong, punctate, with striated margin, generally 

 24-31 x 14-17 ,u, or when elongated 38-45 x 21-24 jz. 



Aecidiospores subglobose or angular, or even oval, deep orange, 

 smooth, 17-21 p diam. or 18-21 x 15-16 p, occasionally as long 

 as 24 .
