Pseudophoenix lediniana is known only from wet forest along small canyons around Riv. Levange (Dep. de l’Ouest), which is the type locality. (S. Zona, A Revision of Pseudophoenix. 2002)A

Discussion

  • Pseudophoenix lediniana is similar in many respects to P. vinifera, but the lobed calyx of P. lediniana is markedly distinct from the unlobed calyx of P. vinifera. The stem of P. lediniana is not strongly bottle-shaped, as in P. vinifera, but rather slightly ventricose. (S. Zona, A Revision of Pseudophoenix. 2002)A

Biology And Ecology

  • In cultivation, Pseudophoenix lediniana is said to be the fastest-growing of all Pseudophoenix. It makes a lovely ornamental palm, but it is not yet common outside the collections of botanical gardens and enthusiasts. (S. Zona, A Revision of Pseudophoenix. 2002)A

Conservation

  • The palm is not valued for wine-making, and the area is under no severe threats by human activities. Nevertheless, the species is highly vulnerable and without protection. (S. Zona, A Revision of Pseudophoenix. 2002)A

Description
