Viburnum bracteatum

''Viburnum bracteatum'' is a species of flowering plant in the Adoxaceae known by the common names bracted arrowwood and limerock arrowwood. It is native to the southeastern United States, where it is limited to Alabama, Georgia, and Tennessee.〔(''Viburnum bracteatum''. ) Center for Plant Conservation.〕 Some authors include ''Viburnum ozarkense'' in this species, which would expand its distribution westward.〔Estes, D. (2010). (''Viburnum bracteatum'' (Adoxaceae) expanded to include ''Viburnum ozarkense''. ) ''Castanea'' 75(2) 277-93.〕 Other authors include ''V. ozarkense'' in ''Viburnum molle'', or retain it as a distinct species.〔Weckman, T. J. (2002). (Reinstatement of ''Viburnum ozarkense'' (Caprifoliaceae): An endemic taxon of the interior highlands of Arkansas, Missouri and Oklahoma. ) ''Sida'' 20(2) 849-60.〕
''Viburnum bracteatum'' is a deciduous shrub with spreading and arching branches reaching up to 3 meters tall. The bark is smooth and gray in color. The oppositely arranged leaves have blades up to 12 centimeters long. They have toothed edges, with about one tooth per centimeter. The blades are borne on short petioles. The inflorescence is 4 to 6 centimeters wide with conspicuous bracts at the base. The flower has a circular corolla of five white petals about 8 millimeters across and five stamens tipped with yellow anthers. The fruit is a bluish black drupe about a centimeter wide. The fruits are eaten by birds, small mammals, and deer.〔(''Viburnum bracteatum''. ) NatureServe.〕
This plant grows in wooded areas with limestone substrates. The overstory includes several types of oak and ''Carya ovata'' var. ''australis''.〔
There are about eleven occurrences of this rare plant, but only five are considered to be viable. It is threatened by limestone mining. This activity has destroyed or partially destroyed populations in the past.〔〔
