Notes: Distribution: French Guiana

General Description

Hemiepiphyte, on tree trunks near the ground. Stems sometimes trailing when preadult, appressed- climbing when adult. Internodes 1-9(17) cm long, (0.5)l-1.5 cm diam., dark green to bluish green, matte to weakly glossy, flattened on one side, drying light yellow-brown to medium reddish brown, drying narrowly ridged (sometimes irregularly so on juveniles). LEAVES: Petioles to 27 cm long, sheathed to within 1.2-1.7 cm of the base of the blade on adult plants (to beyond the base of the blade on juveniles); sheath narrow (the sides ca. 5 mm high), to 10 mm or more wide when flattened, erect-incurled, overlapping at base, erect and incurled toward apex, emarginate and free-ending at apex, dark green and matte, the surface drying finely striate. Blades somewhat inequilateral, one side 0.5-4.3 cm narrower, ± elliptic, rarely narrowly oblanceolate, 6.5-21 cm long, 6.5-13 cm wide when young, usually narrowly oblanceolate, 30-50.5 cm long, 9-20 cm wide, ca. 3 times longer than wide (rarely as little as 1.8 times longer than wide), acuminate at apex, equilateral or only slightly inequilateral and acute to narrowly rounded at base, subcoriaceous, dark green and subvelvety matte when young, becoming weakly glossy when mature, moderately paler and semiglossy below (matte when juvenile), becoming semiglossy, usually drying dark brown above, lighter brown below; margins broadly undulate; midrib obtusely sunken and concolorous to slightly paler above, narrowly raised below (sometimes convex on juveniles) and paler below. Primary lateral veins to ca. 20 per side on adults (5-9 on juveniles), arising at 55-80º angle (45-55º on juveniles), weakly arcuate, weakly quilted-sunken above, weakly raised to convex and paler below, sometimes weakly pleated, drying darker than surface below. Minor veins sparse, moderately distinct below, drying weakly raised and somewhat undulate with rather prominent oblique cross veins. Inflorescences 1-2 per axil. INFLORESCENCE: Peduncle to 3 cm long, largely hidden by the spathe. Spathe 14-17 cm long, slightly constricted above the tube. Spathe tube medium green outside, blade pale green to whitish, the entire inner surface greenish white. Spadix 1 1 - 16.5 cm long; female portion of spadix pale green, to 5 cm long in front, 4.7 cm long in back, to 2 cm diam. midway, 1.8 cm diam. at apex, 1.7 cm diam. at base.


Apparently endemic to French Guiana, known principally from the Montagnes de Kaw at 100-250 m. It is common along the road to Montagne Kaw east of Cayenne. It is also known from a single collection along the road between Cayenne and Regina.
