Dypsis ambositrae is a species of flowering plant in the family Arecaceae. It is found only in Madagascar where it is threatened by habitat loss. Description Dypsis ambositrae is an elegant palm that grows a moderately sized, smooth, ringed trunk to about tall that carries a grayish crownshaft and a crown of gracefully arching, V-shaped leaves with the stiff leaflets drooping at the tip. Generally a solitary palm, but, like many dypsis, often splits and doubles or even triples at or above ground elevation. It usually stays solitary when in regularly burnt terrain. This is a heeled, tillering dypsis. Trunk: 3–7 meters tall, 12 cm in diameter; internodes 10–20 cm apart, pale brown to grey colored (green and ringed when young), nodal scars 0.5 cm, grey; wood hard; base of stem slightly wider, with some surface roots; slight bulge in upper trunk in one older tree; crownshaft pale waxy grey-green. Crown holds 7-11 leaves, spiral, gracefully arching, with stiff pinnae; crownshaft 64–103 cm. long, pale green with a white bloom, ligules 2 cm.; petiole 3–30 cm. long, 3-6 x 2.2-4.5 cm. in diam., channelled with soft edges; rachis 2.1-2.8 m., in mid-leaf 2.2-3.5 cm. wide, green; pinnae 74-84 on each side of the rachis, grouped only very slightly in 2s-5s, in one plane, the pinnae on opposite sides of the rachis at an angle of roughly 130° +-, stiff with only the apices pendulous, apices attenuate, unequally bifid, the proximal 69-144 x 0.3-1.8 cm., (first interval c. 29 cm., more distal 3.5–9 cm.), median 89-114 x 2.3–3 cm (leaflet interval 0.2–2 cm, group interval 2-3.5 cm), distal 18-58 x 0.8-2.5 cm, abaxially with distant tufts of pale grey ramenta over almost whole length of midrib, with scattered scales very faint to invisible, main veins faint, with only the midrib very prominent on the adaxial surface. Inflorescence: Interfoliar, branched to 2 (3 in a few cases) orders, with the basal part within the closed sheath, the prophyll hidden and the peduncular bract spreading from the top of the sheath; peduncle 68–123 cm. long, distally 9 x 5 cm. in diam., green, glabrous, curved outside the sheath; prophyll c. 91 cm., borne at 32 cm. above the base of the peduncle, 11.5 cm. wide, narrowly 2-winged; peduncular bract deciduous, about 80 cm., beaked (about 5 cm.) and closed distally, pale waxy grey, inserted about 48 cm. from the base of the peduncle;
