Dypsis oreophila Beentje, Palms Madagascar : 227 (1995)

Primary tabs



  • Another clustering, montane species, with distinctive small inflorescences. The epithet oreophila means mountain-loving, a reference to the habitat. This is a very attractive species. (Dransfield, J. & Beentje, H. 1995: The Palms of Madagascar)A


Tsaratanana, Marojejy, high ground near Maroantsetra and Mandritsara. (Dransfield, J. & Beentje, H. 1995: The Palms of Madagascar)A


  • Close to D. tsaratananensis, but differs in the much shorter inflorescence rachis (6-9 rather than 24+ cm), fewer leaflets (25-45 on each side of the rachis, rather than 55-60 on each side of the rachis, smaller leaflets (median 14-46, not 55-60 cm), fruit (5-11 x 3-8, not 12-15 x 9-11) and seed (6-8 x 3-7, not 13-14 x 9-11). Most of these characters are not very strong, except for the fruit and seed ones, which in our opinion are important. Maybe further collections will blur the distinctions. It is rather unclear why this was included in Phloga in the Flora (Jumelle and Perrier, 1945). Staminate flowers were unknown, so the only reason must have been its size. Jumelle and Perrier (1945) included Phloga sambiranensis as a synonym, but this has a much longer inflorescence and we believe this is wrong.
    NOTE: the specific epithet was predated in Dypsis; Adelodypsis gracilis Becc from 1906 is a synonym of D pinnatifrons (Dransfield, J. & Beentje, H. 1995: The Palms of Madagascar)A

Biology And Ecology

  • Moist montane forest, on steep slopes; 500-1700 m. Said to be frequent in the forests of the Tsaratanana peaks, between 1000-1600 m (protologue). (Dransfield, J. & Beentje, H. 1995: The Palms of Madagascar)A


  • Vulnerable. The distribution area is limited. The fact that the palm-heart is highly esteemed bodes ill for the future. Numbers unknown. (Dransfield, J. & Beentje, H. 1995: The Palms of Madagascar)A

Common Name

  • Kindro, Lafaza (Antankarana); Fitsiriky (Sambirano Sakalava). (Dransfield, J. & Beentje, H. 1995: The Palms of Madagascar)A


  • Palm-heart edible, highly esteemed. The hollowed out stems are used for blowpipes. (Dransfield, J. & Beentje, H. 1995: The Palms of Madagascar)A
