It should be added that the taxonomic position of Acanthopanax sciadophylloides Fr. & Sav. is uncertain. It is distinct from all other species of Eleutherococcus (Acanthopanax) in being a tree rather than a shrub, in its unarmed branches and in having the umbels arranged in large terminal panicles. In the first and last of these characters it agrees better with Kalopanax and was in fact transferred to that genus by Harms, though it differs from it in its unarmed branches and compound leaves. Hu has not transferred it to Eleutherococcus, holding that it is best left in Kalopanax.
