The shrub here described is a member of a group of 

 eastern Asiatic species nearly allied to the familiar 

 Spindle Tree, Euonymus europaeu*, Linn., but all of them 

 easily distinguishable by their purple anthers. The 

 species figured, E. Uungeanus, which is at once recognis- 

 able by its long-stalked leaves, appears to be confined to 

 Manchuria and northern China. There are records of 

 its presence further south, but the plants referred to 

 are found on examination to belong to other species. 

 In the species here dealt with the scarlet aril arises 

 from the raphe and envelops the greater part of the 

 seed, leaving an irregularly rounded aperture on the 

 side opposite to the raphe. In a recent account of 

 E. Bungeanus (Mitteil. Deutsch. Gesellsch. 1910, p. 107) 

 Dr. Koehne has described an aril of a different type, 

 with an apical opening. As, however, he informs us 



April, 1916.
