Orbexilum pedunculatum, commonly known as Sampson's snakeroot,[2] is a species of flowering plant in the legume family. It is native primarily to the Southeastern United States where it is found in prairies and savannas, often in acidic soil.[3] It is a perennial that produces racemes of flowers in early summer.
Two varieties have been named, which are sometimes considered distinct species.[4] They are:
- Orbexilum pedunculatum var. pedunculatum – Native to a widespread area west of the Blue Ridge Mountains.
- Orbexilum pedunculatum var. psoralioides – Native primarily to the Atlantic coastal plain.
