Description

Tall single trunk reaching 30-40 m; Leaf palmate about 2 m diameter, segmented commences at center or one third way to stalk; petiole length; 2.5-3 m, with sharp thorns; Inflorescence/spadix emerges at petiole axial; fruit oval 8-10 cm in diameter, corky with knurled-textured surface; flesh orange color. Editing by edric.

Palm tree up to 30 m tall. Stem 25–30 cm in diam. Crown of 40–50 leaves. Leaf sheath dissolved in abundant, reddish brown, fibrous mesh, apically extended in up to 40 cm long ligule; petiole 1.6–2.5 m long, glossy dark green, abaxially with two longitudinal stripes, armed with straight 4–5 (–7) cm long, basally swollen spines, distantly inserted and decreasing in length towards the distal end; blade untidy looking with age, up to 2 m across, divided almost to the hastula in 12–14, 3–4-folded segment groups; these again divided to 1/3–2/3 of the radius into single-folded segments, with stiff to eventually drooping tips. Inflorescence, peduncle and rachis more or less equal in length, 0.8–1 m; first order branches 5–7, rachillae numerous, 15–25 cm long. Fruit 10–12 (–15) cm in diam., corky-warty, brown at maturity.

Comments and Curiosities

Malaya. Lowland seasonal swamp forest, along valleys, scattered, endemic. Like Livistona exc. stamens form long tube free from petals, fruits with thick corky cracked outer wall. Flesh orange with strong apricot smell (edible?). Not all leaf divisions to centre, some only 1/3 way in to stalk. (Hijjas Kasturi)

Etymology: Genus Name; Comes from 2 Greek words meaning 'scale' and 'fruit'.

Conservation: Now a rarity due to habitat loss. Most of the swamp forests are subject to forest conversion and forestry activities. Restricted to Peninsular Malaysia and Peninsular Thailand. (IUCN RedList - vulnerable 1998).

"Very tall fan palm from Thailand and surrounding countries- looks, and is probably related to, Livistonas. Has deeply divided, somewhat drooping huge fan leaves (6' wide) on long (6-7') petioles. The most beautiful feature of younger palms (can't appreciate this as palms get too tall) are the ornamental broad yellow stripes along the petioles. Needs a tropical environment to do well, and not aware of any success here in California with this species." (Geoff Stein)

A majestic palm native to swampy lowland areas on the Malay Peninsula. It sports a very tall, slender, solitary trunk that carries a large, spherical crown of bright green, fan-shaped leaves held on fiercely armed leaf stalks with two characteristic yellow stripes. It is closely related to Livistona but easily distinguished by its very large, corky fruits. Pholidocarpus is rarely seen in cultivation and does best in a tropical climate with abundant moisture.
