In addition to the cbaraeters mentioned above S. tzumu differs from S. 

 officinale in the stouter and darker colored brancblets, the larger winter-buds, 

 the larger leaves glaucous beneath, the lobes more acuminate, in the smaller 

 flowers with shorter sepals and stamens and in the somewhat smaller nearly 

 globose fruit. The staminate flowers can be distinguished from the fertile 

 hermaphrodite flowers only by the slightly smaller and often somewhat de- 

 formed ovary which, however, may be sometimes fertile, as the staminate 

 trees, according to Mr. Wilson's observation in China, usually produce occa- 

 sional fruits. The tree, though apparently hermaphrodite, is functionally 

 dioecious, a behavior which I have called elsewhere (Rhodora, vi. 18) 

 pseudomonoclinism.

This species is very similar to S. tzumu, but differs in its 2-loculed anthers, 



a character which I have found constant in a considerable number of flow 



examined. Other slighter differences will be found in the slightly more 



elongated and pointed winter-buds and in the longer and comparatively 



narrower leaves of firmer texture. Judging by the copious material col-
