Comments and Curiosities

A rare small palm from the high mountains (hence the name). This species slightly resembles D. occidentalis, which occurs in the same area. (J. Dransfield and H. Beentje. 1995)/Palmweb.

Conservation: Unclear. Known from a single site only, but the Tsaratanana is not well known botanically. (J. Dransfield and H. Beentje. 1995)/Palmweb.
