Dypsis hovomantsina Beentje, Palms Madagascar : 150 (1995)

Primary tabs



  • An impressive tree; we found a second site only three months before the book went to press. The leaf-sheaths are distinct from any other, with their lower parts white-waxy and a golden-brown furry part at the very top. The name comes directly from the local name, which means stinking and refers to the smelly palm-heart. (Dransfield, J. & Beentje, H. 1995: The Palms of Madagascar)A


Only known from Maroantsetra and Mananara. (Dransfield, J. & Beentje, H. 1995: The Palms of Madagascar)A


  • Possibly closest to D. tokoravina, but with a totally different leaf sheath. (Dransfield, J. & Beentje, H. 1995: The Palms of Madagascar)A


  • inter species maximas foliolis aggregatis vagina folii versus basim glabra ceracea apice brunneo-tomentosa staminibus 6 endospermio homogeneo distincta. (Dransfield, J. & Beentje, H. 1995: The Palms of Madagascar)A
