Viburnum alabamense (McAtee) Sorrie. Alabama Arrow-wood. Hab: Sandstone substrates, slopes, cobble bars in river scour. Dist: Restricted to the Lookout Mountain region of ne. AL, in Cullman, DeKalb, and Marshall Counties and recently found to extend northwards into TN (White County; D. Estes, pers. comm., 2013).

ID notes:We believe taxon "alabamense" is closer to nominate V. dentatum than to V. recognitum), due to the stellate-hairy petioles and broad ovate-rotund leaf shape. HoweverV. alabamense has several characters that diverge from V. dentatum: stipitate-glandular cymes (vs. eglandular), cyme nodes and branches with white hairs (glabrate in V. recognitum), and fruits with glandular surfaces (vs. eglandular); thus deserving specific status (Weakley et al. 2011).

Origin/Endemic status: Endemic

Taxonomy Comments: See Weakley et al. (2011) for additional information.
