Discussion

  • Very similar to D. coriacea but differs in the pubescent leaf sheath, the curved (not erect) inflorescence and the less leathery leaf, at least when fresh. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Diagnosis

  • D. coriaceaesimilis sed vagina folii pubescenti inflorescentia arcuata non erecta et folio vivendi non coriaceo differt. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Biology And Ecology

  • Lowland rain forest; ridgetops; 200-550 m. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Conservation

  • Vulnerable. Occurs over a restricted distribution area, without official protection; numbers are thought to be fairly low. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A
