<div type="description"><p>Solitary, robust palm. Stem ca. 2-6 m long, 4-6 cm diam.; internodes to ca. 15 cm long, smooth, green to greenish-brown. Crownshaft elongate, cylindrical or slightly angular, to ca. 60 cm long, often swollen. Leaves to 7 in crown; leaf sheath ca. 2045 cm long, pale green with dull purplishbrown specks; petiole ca. 10-55 X 1.5 cm. Leaflets to 30 on each side of the rachis, drying brown; basal leaflets narrowly linear-acuminate, 1 costate, ca. 3040 X 0.7-1.3 cm; middle leaflets 2-3 (5) costate, ca. 30-65 X 1-3 (5) cm, longacuminate; terminal leaflet pair 2-4 (6) costate, ca. 25-40 X 1-3 (4) cm, longacuminate or slightly toothed at tips, the pair sometimes joined to 9 cm at the base along the rachis. Inflorescence infrafoliar, subpendulous to pendulous; prophyll ensiform or lanceolate, ca. 20-30 X (3.5) 45 cm, slightly purplish, drying brown, caducous; peduncle ca. (1.5) 2-3 (3.5) X 1-1.8 cm, flattened, glabrous; peduncular bract narrowly triangular, to ca. 3.5 cm long, 8 mm wide at the base, membranous; rachillae 3-4, rarely to 5, ca. 2545 cm long, to 8 mm thick, glabrous, each subtended by a membranous, triangular bract to 5 X 5 mm. Staminate flower triangular, asymmetric, flexuous; sepals equal or subequal, subulate, acutely and dorsally carinate, flexuous, ca. 6-13 mm long; petals elliptic to elliptic-Ianceolate, acuminate, equal or subequal to the sepals; filaments ca. 2 mm long; anthers erect, linear, ca. 3-4 mm long, sagittate at base; pistillode of 2-3 tubercles. Pistillate flower shorter than the staminate flower; sepals ca. 4-6 X 5-6 mm, petals as the sepals, often smaller, ca. 4 X 3-4 mm; ovary ovoid to subglobose, to 3 X 2 mm; stigma distinctly 3-lobed; staminodes of 6 minute teeth. Infructescence pendulous. Fruit ripening purplish-black, ellipsoid, ca. 3-4 (4.5) X 1.3-1.7 cm, prominently beaked, tipped with a distinct 3-lobed stigma to 3 mm high, the lobes erect; epicarp often drying with longitudinal ridges; the inner apical part usually with a distinct cylindrical or conical, corky solid tissue. Seed broadly ovoid, ca. (1.2) 1.5-1.6 (1.8) X (0.7) 1-1.2 cm, abruptly spinescent at tip; base truncate, shallowly concave.</p></div>

<div type="distribution"><p>S. Thailand and Malay Peninsula.</p></div>

<div type="biology_ecology"><p>In dense humid forest; ca. 150-1,300 m alt., more widespread in the Malay Peninsula where it is common at higher altitudes.</p></div>

<div type="discussion"><p>This species is apparently a strictly solitary palm, although it has sometimes been erroneously reported as occurring in clumps. Nenga macrocarpa is easily distinguished by its staminate flowers with equal or subequal perianth parts, and its large ellipsoid fruits which are prominently beaked and tipped by a distinct 3-lobed stigma. </p></div>
