■ 



(Veitch Exped. No. 3495). Western Kansu: Tibetan country, 

 south of Tow River, 1910, W. Purdom. 



This is a very distinct species, and is easily distinguished from all others by 



its usually broadly ovate, 3- or sometimes 5-lobed and sharply serrate, glabrous or 



glabrescent leaves 3-nerved at the base, and by the red ovoid fruit with a decid- 

 uous calyx.

This species much resembles in its leaves M. Tschonoskii Schneider, but is easily 

 distinguished by its smaller flowers in many-flowered corymbs, by the much smaller 

 red fruits with refiexed calyx-lobes and by the more distinctly lobed, sharply and 

 closely serrulate leaves.
