  • Viburnum dentatum is a polymorphic species, meaning that it has more than one form or morph.   With V. dentatum there are several similar and related forms and species and together they are referred to as the "dentatum" complex.  This complex includes, but not limited to, V. bracteatum, V. rafinesquianum , V. ozarkensis, and V. recognitum.  Dirr (2009, p.1200) creates the following image of the variation in Viburnum dentatum  "...envision this group as a north-south, east-west continuum showing slight differences in leaf characteristics, pubescence, habit and size but possessing similar creamy white flowers and blue to blue-black fruits...".
  • dentatum: toothed, a reference to the leaves.
