This small tree is common all through central and western China up to an alti- 

 tude of 1300 m. It is colloquially known as the " Ku-lien-shu " and the bark is 

 highly esteemed as a drug. This tree has a very extensive geographical range, 

 and although it varies slightly in degree of pubescence it is otherwise remarkably 

 constant in its characters.
