Western Szech'uan : Kuan Hsien, thickets, alt. 800 m.. November 1908 (No.

The pubescent under side of the leaves distinguishes /*. hypotricha easily from 

 the other Asiatic evergreen species of the subgen. Pndu.'i. It is apjiarently most 

 closely related to P. macrophylla Siebold & Zuccarini which differs in the longer and 

 narrower, more remotely and coarsely serrate leaves glaln-ous beneath and of thicker 

 texture. A. R.
