This species is distinguished from both Aralia spinosa and A. chinensis 

 by the form of the inflorescence. In these two species the main axis 

 of the inflorescence is elongated terminating the branch of the current 

 year. Thus the inflorescence forms a terminal erect panicle. In A. elata 

 the axis of the inflorescence is short and its main branches are well devel- 

 oped and more or less umbellate. The main branches of the inflores- 

 cence become themselves panicled spreading when in flower and drooping 

 in fruit. Aralia spinosa has distinctly stalked leaflets by which it is 

 distinguished from either A. data or A. chinensis. A. chinensis has or- 

 dinarily finer serrations and more tapering leaflets than A. elata. We 

 have an imperfect glabrescent specimen from Formosa. It lacks the 

 inflorescence and I cannot ascertain to what species it really belongs. 

 According to S. Sasaki this type grows in the whole island of Formosa 

 below 1000 m. above sea-level and does not branch. A specimen from 

 Western China (Wilson's no. 3692) has the leaflets minutely but sparsely 

 ciliated all over the lower surfaces, but the pubescence is not velutinous 

 as in the type.
