Introduction

  • A fairly rare species from lowland rain forest, but highly distinctive. The name faneva (flag in Malagasy) refers to the leaves, which are remarkable for the large terminal flabellum. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Discussion

  • Distinct from the very similar D. mangorensis in the more-branched inflorescence with shorter rachillae, and from the similar D. procera and D. paludosa in the six (not three) stamens. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Diagnosis

  • D. boivinianae affinis sed inflorescentia in plures ordines ramificanti rachillis brevibus D. procerae et D. paludosae superficialiter similis sed staminibus 6 non 3 differt. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Biology And Ecology

  • Littoral forest or moist lowland rain forest, on steep or level slope; 1-300 m. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Conservation

  • Endangered. The lowland rain forest in this area is not well protected, and numbers are low; we have seen less than fifty individuals. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Common Name

  • Tsinkiara mavinty (Betsimisaraka). (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Uses

  • None recorded. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

STEMS 3-6 m, 3-5 cm diam.; somewhat stilt-rooted at base; internodes 3-10 cm, brown; wood soft; crownshaft moderately well-developed, with occasionally a yellowish stripe below the rachis. LEAVES 8-9 in the crown (sometimes with up to 4 marcescent leaves present), spirally inserted, porrect and arching; sheath pale creamy yellow or green, spotted with red, 24-30 cm long, with scattered brown scales (distally rather dense), with auricles to 3.2 cm high; petiole absent or up to 10 cm long, with scattered scales, channelled adaxially, 9-10 x 5-6 mm diam.; rachis 79-94 cm long, in mid-leaf 5-6 mm wide, with scattered scales; leaflets 8-21 on each side of the rachis, regular, stiff, straight, in one plane, somewhat arcuate, 1-4 folds wide, proximal 25-63 x 0.1-3.6 cm, median 62-72 x 1.7-11 cm (interval 6-7.5 cm), distal 42-55 x 7-10 cm, main veins 1-4, apices long-attenuate, main veins with ramenta, minor veins with scattered scales, distal pair joined for 11-17 cm, with 8 main veins, apices dentate over a width of 2-2.2 cm. INFLORESCENCE interfoliar, branched to 2 orders, spreading, c. 50 x 50 cm; peduncle 28-64 cm, distally 1.2-1.7 x 0.5-1 cm diam., rusty-pubescent; prophyll 29-54 cm long, borne at 13-17 cm above the base of the peduncle, 2.2-2.5 cm wide, with scattered scales, opening for the distal 4-6 cm; peduncular bract inserted at 21-30 cm from the base of the peduncle, 12-30 cm long, split over its distal 10-14 cm; rachis 14-19 cm, with 4-6 branching and 7-16 unbranched first order branches (the proximal with an axis of 9 cm, with 5 rachillae), all axes hairy; rachillae 10-28 cm long, with scattered scales, with distant triads. STAMINATE FLOWERS orange in bud; sepals 1.3-1.8 x 1.2-1.5 mm, the middle one sometimes very asymmetrical; petals 1.9-2.8 x 1.5-2.1 mm; stamens 6, didymous, 1- or biseriate (offset to 0.4 mm), filaments 0.8-1 mm, fat and ellipsoid, anthers 0.6-0.7 x 0.7-0.9 mm; pistillode c. 1 x 1.2 mm, pyramidal.
