The type of D. poivreana has the description 'palmier aquatique' which seems unlikely. Alt., low elevations.


Solitary palm to 80 cm high. STEM about 8 mm in diam.; internodes 2.5-4.5 cm, densely pubescent distally. LEAVES about 8 in the crown, entire; sheath 11-13 cm long, 1/2 to 2/3 closed, with dense scales, auricles 0.7-1 cm; petiole 3-19 cm long, distally 2-3 mm diam., densely scaly or with scattered scales; lamina entire, 24-42 cm long, midrib 5-10 cm long, lobes 19-37 x 2.4-4.5 cm, main veins 5-7, with scattered scales on minor and major veins, apex dentate over a width of 4-12 mm. INFLORESCENCE unbranched; peduncle 14-26 cm long, about 2 mm in diam., densely red-pubescent; prophyll 6-13 cm long, 4.5 mm wide, with reddish flaking pubescence, borne at about 4 cm above the base of the peduncle, open in the distal 1-1.5 cm; peduncular bract inserted at 6-21 cm from the base of the peduncle, 8-14 cm long, with scattered scales, open in the distal 2 cm, sometimes with a 5 mm beak; non-tubular peduncular bract sometimes present, about 2 mm; rachilla 11-26 cm, 1.5-2 mm in diam., densely scaly, with spaced triads. STAMINATE FLOWERS with sepals 1.3-1.7 x 0.8-1.8 mm; petals on a 0.2-0.4 mm high receptacle, 2-2.6 x 1.3-1.7 mm; stamens 6, biseriate (offset 0.2-0.3 mm), filaments 0.9-1.7 mm and thin (and occasionally connate for about 0.2 mm), anthers 1.3-1.8 x 0.4-0.6 mm, versatile; pistillode 0.6-1 x 0.3-0.5 mm, pyramidal. PISTILLATE FLOWERS with sepals 1.2-2.2 x 1.6-2.1 mm; petals 3-3.9 x 2.8-3.6 mm; staminodes 0.3-0.9 mm; gynoecium 2.8-4 x 2-2.6 mm, trifid. FRUIT unknown. (J. Dransfield and H. Beentje. 1995)/Palmweb.

This species slightly resembles D. digitata but is distinct in its shorter petioles and closed leaf sheaths; it is close to D. andapae, but that species clusters and occurs in high mountains. (J. Dransfield and H. Beentje. 1995)/Palmweb.


Comments and Curiosities

A small solitary undergrowth species from littoral forest, distinct by its entire, deeply lobed leaves and long unbranched inflorescence. The name refers to the collector of the type, Pierre Poivre (1719-1786). (J. Dransfield and H. Beentje. 1995)/Palmweb.

Conservation: Critical. Known from only a very small area, in which this kind of vegetation is disappearing rapidly. Not seen in the last twentyfive years. (J. Dransfield and H. Beentje. 1995)/Palmweb.
