Eleutherococcus sieboldianus B. S. Walters

A Japanese species, first collected by B. S. Walters, M. R. Penskar, and D. Landis in 2005 at the shrubby edge of a gravel road through a wetland in Jackson Co.

This is a commonly cultivated arching, prickly shrub useful because of its tolerance of dry shade. It is known in older literature as Acanthopanax sieboldianus. Aside from the familiar genus Rubus, this is our only prickly woody plant with palmately compound leaves.
