Leaves spirally arranged; sheaths 30-75 cm long, disintegrating into black fibers, with a prominent, fibrous ligule at the apex; petioles 1-1.5 m long; rachis 0.8-1.3 m long; pinnae 5-10 per side of rachis, regularly and alternately arranged, spreading in the same plane, proximal 2-3 pinnae in a cluster, pinnae from middle of leaf 57-77 cm long, 6-8 cm wide at widest point, lanceolate, scarcely lobed. Inflorescences unixexual, subtended by smaller leaves, staminate and pistillate borne on the same stems, the pistillate terminal, the staminate lateral; staminate inflorescences not seen in their entirety; rachillae to 10, to 20 cm long, 2-2.5 mm in diameter; staminate flowers to 6 mm long; sepals 1.5 mm long, connate into a cupular calyx, very briefly lobed; petals 6 mm long, purple; stamens 16-19; pistillate inflorescences not seen; rachillae to 11 cm long, 3.5 mm in diameter; pistillate flowers to 3 mm long; sepals to 0.5 mm long; petals 3 mm long; gynoecium 1.5 mm long; fruits ovoid to ellipsoid, to 1.1 cm long, to 0.8 cm in diameter, red or purple.

Distinguished from other species by its lanceolate pinnae and purple staminate flowers with 16-19 stamens. One specimen from Thailand (Kanchanaburi: about 30 km NW of Thong Pha Phum on highway 323 to Myanmar border, about 20 km E of Koeng Ka Vin and Pawanaputso Temple, 500 m, 1 Nov 1997, Hodel & Vatcharakorn 1765 (BH, MO)) has lanceolate pinnae as in W. marianneae and 12 stamens as in W. caryotoides. It is illustrated in Hodel (1998), plate 83c. It may be a hybrid between W. marianneae and W. caryotoides. (Henderson, A.J. 2007)/Palmweb.
