Flora of Virginia Name/Status
Endotropis lanceolata (Pursh) Hauensch.
Two partially sympatric varieties are often recognized but appear to be of questionable taxonomic significance. Var. lanceolata, primarily of the Appalachian region, has pubescent leaves and twigs while var. glabrata Gleason) has glabrous leaves and twigs and occurs primarily west of the Appalachians. However, plants with intermediate characters are reportedly widespread in the main, midwestern range of the species, making the distinction problematic. Most Virginia material apparently conforms to var. lanceolata, but a population matching var. glabrata has been documented by J.C. Ludwig in Russell County.
Dry woodlands and barrens over limestone and dolostone, as well as fencerows and old fields on these substrates. In Virginia, it is confined to, and infrequent throughout, the Ridge and Valley province.
