Lépini
Indigenous quite rare tree of semi-evergreen seasonal forest.
Guadeloupe, Marie Galante, Dominica, Martinique, St. Lucia, St. Vincent, Grenada, Trinidad, Mesoamerica, South America.

Specimens labelled as Zanthoxylum martinicense (Lamarck) de Candolle are in the herbarium and this species is listed for St. Lucia in FLA. However the specimens seem to me to be Zanthoxylum microcarpum. My collections have all been determined to be Zanthoxylum microcarpum.
Zanthoxylum martinicense may not be present in St. Lucia.
