Description
Clustering palm to 1 m tall. STEMS < 4 mm in diam. LEAVES about 5 in the crown; leaf sheath 7-9 cm long, proximally glabrous, distally with patches of reddish indument, with small triangular auricles 2-5 mm high; petiole 2.5-5 cm long, about 2 mm in diam., with scattered scales; rachis 16-27 cm long, in mid-leaf about 2 mm wide, with scattered scales; leaflets 3-5 on each side of the rachis, the proximal 10-13 x 0.9-2 cm, median 11-16 x 1.5-2.4 cm, distal pair forming a flabellum 16-22 cm long, connate for 7-8 cm, leaflet interval 1-3 cm, but usually with a large gap just below the terminal flabellum, with scattered scales on the abaxial surface, main veins 1, to 7 on the terminal flabellum. INFLORESCENCE interfoliar, unbranched; peduncle 23-27 cm long, densely scaly; prophyll 10-12 cm long, 3-5 mm wide, open only near the apex; peduncular bract inserted at 4.5-13 cm from the base of the peduncle, 7.5-15 cm long, split in the distal 5-9 cm; rachilla 10-14 cm long, 1-2 mm in diam., densely stellate-puberulous, with distant triads.

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