Ecologie : V. planifolia is/has been cultivated in E. Africa, Zaire, Gulf of Guinea Islands, and plants are often found in a more or less naturalised state. – V. bampsiana was collected in Zaire, Forestier Central, Bikoro (0°45’Sx18°07’E), in dry forest (specim. Lebrun 1459).
  The genetic variation of V. planifolia was studied by Schlüter & al. (Econ. Bot. 61: 328-336, 2007): They distinguished 3 geographical groups, and conclude that “cultivar names…do not appear to reflect genetically defined groups”.
