New combinations in Asarum (Aristolochiaceae) for two recently described Hexastylis species
New combinations in the genus Asarum are proposed for Hexastylis finzelii B.R. Keener and Hexastylis rollinsiae B.R. Keener & Todia, two species recently described from Alabama. Asarum finzelii (B.R. Keener) Diamond and Asarum rollinsiae (B.R. Keener & Todia) Diamond, comb. nov., provide names for these species in Asarum.
