Description

Clustering palm in tufts of 3-4, occasionally appearing solitary. STEMS 2.5-5 m high, 1-1.5 cm in diam.; internodes 2.5-6.5 cm long; stem occasionally with basal aerial roots to 20 cm long. LEAVES 6-11 in the crown, spirally inserted, entire or rarely with a few leaflets, arching; sheath green, 12-15 cm long, pale reddish-brown when dry, with few scattered scales, with about 5 mm high ligules; petiole absent or up to 8 cm long; lamina entire and 57-62 cm long, with scattered scales on the minor and major veins, the midrib 20-21 cm long, the lobes 34-39 x 4.3-8.5 cm, the apices narrowly dentate; or pinnate with rachis 18-24 cm long; 2 (-3) leaflets on each side of the rachis, the proximal 15- 56 x 0.5-5.3 cm, the distal 40-44 x 3-4.1 cm, main veins 5, with scattered scales on minor and major veins, proximal leaflets acuminate, distal ones dentate over about 5 mm, distal pair joined for about 7 cm. INFLORESCENCE interfoliar, branching to 1 order, porrect with pendulous rachillae; peduncle 24-47 cm long, with a few scattered scales; prophyll 22-27 cm long, opening in the distal 2-4 cm, with scattered scales; peduncular bract inserted at about 20 cm from the base of the peduncle, about 16 cm long, opening in the distal 3 cm, with scattered scales; rachis 2-13 cm, with 3-7 rachillae; rachillae 16-25 cm long, green, puberulous in the triad depressions, with distant yellow buds. STAMINATE FLOWERS with sepals 0.7-0.8 x 0.6-0.7 mm; petals 1.2-1.6 x 0.9-1 mm; stamens 6, biseriate (offset about 0.2 mm), didymous, connate for about 0.3 mm, filaments about 0.5 x 0.4-0.5 mm, anthers about 0.3 x 0.5 mm; pistillode 0.3-0.4 x 0.4 mm. PISTILLATE FLOWERS unknown. FRUIT unknown. (J. Dransfield and H. Beentje. 1995)/Palmweb. Editing by edric.

Remarkably like D. mangorensis - but for the short petiole, the more slender rachillae with less conspicuous bracts, and the didymous anthers. Close but not the same is Perrier 12038 (P), Antalaha: Marambo, Oct 1912 (young bud), which has larger staminate sepals. The stamens are too young to study. (J. Dransfield and H. Beentje. 1995).

Culture

Small entire leaf Dypsis sometimes leaf can split but only once or twice a little harder to grow than most other small Dypsis preferring temperature above 15.C. Will grow in a protected warm spot in subtropics and likes deep rich soil with a good mulch and regular fertilizing. Growing Climate: -Temperature from 2.C to 40.C.

Comments and Curiosities

Rather like D. faneva, but with entire or hardly dissected leaves. The name comes from the local name for the species. (J. Dransfield and H. Beentje. 1995)/Palmweb.

Conservation: Endangered. Known from a single site, outside the protected area, where we have seen less than fifty individuals. (J. Dransfield and H. Beentje. 1995)/Palmweb.
