Xear SJcimmia melanocarpa Eehdeu et WiLSOX, but distinguishable from 

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

 wliich aro always obtuse at the apex of tlie acumens. 



Shimmia arisancnsis Hayata, S. distinctc-venulosa Hayata and S. ortho- 

 clacla Hayata resemble one another very closely. Slcimmia oHlioclada difFers 

 from the otlier two by the thinnest and hirgest leaves with the canaliculated 

 costa on the upjier sm-f;ice and by its smallest form attaining less than 2 

 meters, with erect stems and branches ; 5^. distinctc-vemdosa distinguishes itself 

 by its uarrciwest oblanceolate leaves with visible peculiar reticulatious of thc 

 veinlets ; wliile S. arisanensis Hay. differs from S. oHhoclada in much larger 

 form, in its smaller thicker leaves with elevated costa on the upper sm-face, 

 and from S. distinctc-venulosa by thc broader obovate or oblong leaves with 

 no visible pcculiar reticulation and by its erect habit.
