N. Dumetz, WHAT REMAINS OF A TROPICAL FOREST BECOMIN G EXTINCT IN MADAGASCAR (THE ANCIENT HUMBERTIA-MADAGASCARIENSIS FOREST), Comptes rendus de l'Academie des sciences. Serie 2, Mecanique, physique, chimie, sciences de l'univers, sciences de la terre, 318(7), 1994, pp. 1009-1014
Field work, cartography and floristic analyses proved us the existence
of a large physical and botanical unity on the South Eastern Madagasc
ar lava flows. Today colonized by herbaceous vegetation cover, it was
the old seating of the Humbertia madagascariensis Lam. (Convolvulaceae
) Eastern lowland forest of which some traces still exist today.
