Distribution wide ranging and is reportedly common in South America and Africa. It is known in Panama by only one collection taken in Central Panama about halfway across the Canal.
Note Vignajuruana is similar to V. iongifolia, but it differs in having smaller flowers and fruits, in being much less pubescent, especially on the stems, and in having ovate instead of narrow leaflets.
Specimen CANAL ZONE: Gamboa, Tyson 4584 (FSU, SCZ).
