INFLORESCENCES solitary or occasionally paired; cataphylls 6.9-17.9 cm long, 0.4-1.6 cm wide, lanceolate, sharply 2-keeled; peduncle (2.7-) 3.7-7.4 (-13.0) cm long, P/S=0.31-0.85, obscured by sheath; spathe at anthesis 10.0-23.5 cm long, 2.9-5.3 cm wide, externally dark green on tube, medium green on blade and margins of tube, pale green to white within; spathe drying moderately and uniformly granular and short-white-lineolate externally, internally densely and conspicuously white-granular, with longitudinal secretory striations to at least 6/7 to apex; acumen of spathe 1.0-2.5 cm long. Stipe of spadix ca. 0.7-1.7 cm long; spadix 8.7-21.2 cm long, the fertile male portion 0.9-1.7 cm wide, creamy-white, deleted slightly forward at anthesis; sterile male zone 0.6-1.3 cm long; female portion of spadix 2.1-4.7 cm long, F/S=0.17-0.31, 1.5-2.1 cm wide, pale green; fertile male flowers 1.8-2.4 mm long, 0.6-1,5 mm wide, irregularly polygonal, columnar; sterile male flowers 1.6-4.0 mm long, 1.3-2.4 mm wide, climate; female flowers 2.3-4.0 mm long, 0.7-1.1 mm wide, the style with conspicuous raphides. INFRUCTESCENCES: Ripe fruits unknown. Seeds unknown.

Habitat

rain-forest,'' or forêt hygrophytique caraïbe'' (Stehlé 1946).

Distribution

Endemic to the West indies, from the eastern Greater Antilles (Hispaniola, Puerto Rico) and the Virgin Islands through the Leeward and Windward chains of the Lesser Antilles to St. Vincent and (possibly) Barbados.

Uses

According to Questel (1951), the filiform roots of P. lingulatum are employed on Guadeloupe for cordage, wickerwork, and basketry. Duss (1897) reported that woodsmen in Guadeloupe use the sap from the roots and stems to cleanse wounds.
