ARALIACEAE. — ACANTHOPANAX 559 



shan, thickets, alt. 1200-1800 m., August 1908 (No. 1966; bush 2-3.3 

 m. tall, flowers green). 



This variety resembles the preceding; variety in its leaflets being pubescent 

 beneath, but the leaves are always 5-foliolat.e, the leaflets smaller and narrower, 

 generally oblong-obovate, distinctly doubly serrate and furnished with spreading 

 or slightly reflexed bristles on the petiole and on the midrib beneath. Wilson's 

 No. 323'^ and Henry's No. 6503^ differ from the type in the leaves being pubescent 

 only on the midrib, and in Henry's No. 5950" the bristles are wanting on both the 

 petiole and the midrib; in Wilson's No. 1966 the bristles are nearly wanting. The 

 stem may be prickly or nearly unai-med.

This species is very closely related to A. leucorrhizus Harms, but is easily dis- 

 tinguished from it by the leaves with almost invariably 3 leaflets (among 18 sheets 

 with approximately 140 leaves we found only three leaves with 5 and one with 4 leaf- 

 lets), by their glaucous under side, their more coriaceous texture and by their more 

 remote and shallower serration; in the type specimens this is restricted to the up- 

 per part of the leaflets, while in almost all other specimens it extends nearly to the 

 base. The inflorescence consists of several usually rather short-pedunclcd umbels, 

 while in A. leucorrhizus there is usually one long-stalked umbel, occasionally with 

 a few short-stalked smaller ones at its base. 



Here is added a species not collected during the Arnold Arboretum Expeditions.
