SC, VA): disturbed areas; uncommon (VA Watch List). June-October. Widespread in the Western Hemisphere. The more
familiar name, L. filiformis, must be replaced for reasons of nomenclatural priority. [= FNA, K; < L. filiformis (Lamarck) Palisot

further west. July-August. Widespread in the Western Hemisphere, the native range obscure, but not likely native in our area.
