Varieties of dioica may not be clearcut (Y), but they are reported from diverse habitats, and their ranges are somewhat segregated or fragmented in southeastern states (Gl, Cr, W). The following three taxa are provisionally combined here. [A somewhat parallel situation exists within Viburnum rafinesquianum.] Var. glaucescens, sensu stricto, is a largely northwestern taxon that is generally more pubescent than var. dioica in leaves and flowers (Hill 2003a). Var. orientalis Gleason is a similar eastern taxon, with generally hairy leaves plus glandular hypanthia; its type is from CART (NY) and there are other Ky. colls. from PULA, ?JESS and ?WAYN. Var. dasygyna (Rehd.) Gleason is similar to orientalis, but with dense long hairs on hypanthia as well as glands; it may be known only from Ind. and Ohio, plus a recent report from CART in Ky. (CW).
