 Aprili. 1914. 



Near Skimmia melanocat-pa REHDER et WILSON, but distinguishable from 

 it by the larger panicles and much more rounded petals and by the leaves 

 which are always obtuse at the apex of the acumens. 



Skimmia arisanensis HAYATA, S. distincte-venulosa HAYATA and S. ortho- 

 clada HAYATA resemble one another very closely. Skimmia orthoclada differs 

 from the other two by the thinnest and largest leaves with the canaliculated 

 costa on the upper surface and by its smallest form attaining less than 2 

 meters, with erect stems and branches ; 8. distincte-venulosa distinguishes itself 

 by its narrowest oblanceolate leaves with visible peculiar reticulations of the 

 veinlets ; while S- arisanensis HAY. differs from S. orthodada in much larger 

 form, in its smaller thicker leaves with elevated costa on the upper surface, 

 and from S. distincte-venulosa by the broader obovate or oblong leaves with 

 no visible peculiar reticulation and by its erect habit.
