This new sj^ecies is well characterized by its glabrous, entire or nearly 

 entire leaves, pale or glaucescent and indistinctly veined beneath. It is 

 most cbsely related to P. Gihhsii A. B. Jackson which differs in its o])ovate 

 to obovate-oblong or spatulate leaves, gradually narrowed toward the base, 

 coarsely crenate, light green beneath and with distinct secondary veins and 

 in the quite glalrous sepals. In the entire or nearly entire leaves and in 

 their oblong shape it resembles C. angusiifolia Schneider, but that s])ecies 

 differs in the tonientosc pubescence of the under side of the mucli nar- 

 rower leaves and of the denser and few-flowered inflorescence. The three 

 specimens from Kwei-chou agree with the type specimens in the size and 

 shape of the leaves, while Wilson's Nos. 349 and 602 have smaller leaves, 

 not more than 3 cm. long and occasionally aculish or acute.
