This differs from the Hainan Dendropanax oUgodontjis Merr. & Chun 

 in its coriaceous, more prominently nerved leaves and particularly in its 

 free or nearly free spreading or recurved styles, the style of D. oligo- 

 dontus being simple and columnar. Dendropanax Chevalieri ( Viguier) 

 comb. nov. {Gilibertia Chevalieri Viguier in Lecomte, FI. Gén. Indo- 

 Chine 2: 1181. /. 141. 1923), the only other species of the genus hitherto 

 recorded from Indo-China, has the free styles of the présent species but 

 its leaves are entire, and apparently with much fewer primary latéral 

 nerves. Gilibertia Ruiz & Pavon is invalidated by the earlier Gilibertia 

 Gmelin, Dendropanax Decne. & Planch. being the next older name. 

 Textoria Miquel, based on a Japanese species, is apparently not gen- 

 erically distinct from the American forms.
