Description

Stem about 5 m tall, fusiform or ventricose, 25.1–32.5 cm in diameter breast high, gray, with prominent leaf scars when young. Leaves 15–17 in the crown, spreading; leaf about 270–310 cm long; sheath 36.0–58 cm long, green with silvery gray scales near the apex; petiole 25–60 cm long; rachis about 236 cm long, often with brown scales along its margin; leaf segments 140–160 per one side of the rachis; middle leaf segment 49.0–66.5 cm long, 1.6–2.5 cm wide, lanceolate with an acuminate tip, gray-green, glaucous abaxially, glaucous to glossy adaxially, ramenta absent on the abaxial surface of the midvein at the base of the leaf segment. Inflorescence arching to pendulous, branched to 3 orders, about 1.7 m long; peduncle about 95 cm long and 4.0 cm in diam., glabrous; prophyll about 104 cm long, about 8.5 cm wide, bearing dark brown scales along both edges (keels); inner bract not seen; rachillae 13.0–14.7 cm long and 1.5–1.7 mm in diam., directed toward the apex of the inflorescence. Flower pseudopedicel 0.7–2.0 mm long, 1.4–1.7 mm in diam., green to glaucous; calyx a shallow three-lobed cupule, 4.0–5.2 mm in diam., lobe apices rounded, green to glaucous, margins hyaline; petals ovate, 5.5–6.0 mm long, 4.7–4.9 mm wide, green, glaucous abaxially, spreading, with about 12 major veins; filaments about 2.1 mm long, not connate, anthers ovoid, about 4.3 mm long and 2.1 mm wide, yellow; gynoecium (in bisexual flowers) about 3.2 mm long and 2.0 mm in diam.(pistillode in staminate flowers smaller), green. Fruit 17.2–25.1 mm long, 14.8–21.7 mm in diam. (in single-seeded fruits); endocarp 15.2–17.6 mm long, 15.6–17.3 mm in diam., about 0.5 mm thick. Seed 12.3–14.6 mm long, 10.9–14.2 mm in diam. (S.

Pseudophoenix lediniana is similar in many respects to P. vinifera, but the lobed calyx of P. lediniana is markedly distinct from the unlobed calyx of P. vinifera. The stem of P. lediniana is not strongly bottle-shaped, as in P. vinifera, but rather slightly ventricose. (S. Zona. 2002)

Culture

Sunny, moist, but well drained position. Cold Hardiness Zone: 10a.

Comments and Curiosities

Conservation: The palm is not valued for wine-making, and the area is under no severe threats by human activities. Nevertheless, the species is highly vulnerable and without protection. (S. Zona. 2002)/Palmweb.

Critically Endangered; Found in the south-west peninsula. In 1989 only 30 trees were found in the wild. (ICUN Redlist)

Uses: Locally; the fruit is fed to livestock.

In cultivation, Pseudophoenix lediniana is said to be the fastest-growing of all Pseudophoenix. It makes a lovely ornamental palm, but it is not yet common outside the collections of botanical gardens and enthusiasts. (S. Zona. 2002)/Palmweb.
