Sori containing both urediniospores and teliospores, scattered,

 cinnamon brown, with two or three germ-spores; teliospores oblong, 

 not clavate nor constricted at the septum, apex not thickened ; 15-24//, 

 by 29-41/*, brown, pedicel short and hyaline.

This species is more closely related to P. Adeiiostegi-ae Arth. than 

 to P. Anthirrhini Diet, and Holw. ; it differs from the latter in the 

 characters of the sori, and from both in the form and size of the telio- 

 spores. These differences are shown in the figures given below, which 

 represent the results of the measurement of forty mature spores of 

 each of the three species.
