This variety is chiefly distinguished by its rather dense pubescence. The type 
agrees in the stems being woody at the base and the leaf-bases rounded, but 
differs in its more coarsely toothed glabrescent leaves, polygamo-dicecious flowers 
and sparsely villose achenes. Var. Davidiana differs in its herbaceous habit, 
cuneate leaves, glabrescent and coarsely toothed, and more sessile densely clus- 
tered inflorescence. In general appearance this new variety comes nearest to the 
form found in Shantung, which, however, has more coarsely toothed, less hairy 
leaves, usually cuneate at the base and unisexual flowers. The Shensi specimen 
collected by Giraldi is somewhat less pubescent than the other specimens.
