    General Description

    Epiphyte; internodes short, 1.5 cm diam.; cataphylls 10 12.5 cm long, fibres pale to reddish brown, persisting in part intact, more loosely fibrous toward the base. Leaves with petiole 13.2-22.6 cm long, 0.2-0.4 cm diam., narrowly sulcate, subterete (margins moderately acute), dark green, weakly glossy; geniculum 2-5 cm long; blade oblong-elliptic to weakly oblong-oblanceolate, 27.6-46.4 cm long, 6.9-9.9 cm wide, 3.18-5.16 longer than wide, 1.33-2.16 longer than petioles, gradually and narrowly long-acuminate at apex, acute at base, moderately coriaceous, dark green and weakly glossy above, moderately paler and weakly glossy below, drying grey green or greyish yellow-green above, sparsely short pale-lineate and lacking glandular punctations above but densely dark granular at high magnification above, drying brownish olive-green to dark brown and dark glandular-punctate, densely pale-speckled below; midrib narrowly raised and slightly paler above, bluntly acute and paler below, drying acutely, closely and irregularly ribbed and paler above and below; primary lateral veins 8-10 pairs, arising at a 40-55° angle, etched and con colorous above, weakly bluntly acute and concolorous below, drying concolorous on both surfaces, drying nar rowly rounded to moderately thicker than broad, minute ly granular above, sparsely glandular-punctate below; basal veins 1-2 pairs, both free to base; collective veins 1 pair, arising from the base or very near the base from the uppermost basal vein, 4-8(-11) mm from the margins, weakly loop-connecting the primary lateral veins, sunk en above, narrowly raised below. Inflorescence erect; peduncle purplish violet, several-ribbed, 33-56.8 cm long, 4-5 mm diam., sharply 10-14-ridged, sometimes somewhat flattened on one side, weakly glossy, yellow green, densely short-purplish-lineate throughout; spathe 11.8-14.7 cm long, 1-1.9 cm wide, narrowly lanceolate triangular, reflexed-spreading, recurled, medium green, weakly glossy inside, semiglossy and tinged purplish outside, inserted at a c. 30°  angle; spadix sessile, shape tapered, 9.4-18.8 cm long, 3.5-4 mm diam., dark vio let-purple, matte. Flowers rhombic, 1.8-2.5 mm long, 1.3-2.2 mm wide; 8-9 flowers visible per spiral; tepals 1 mm wide, semiglossy, outer margins 2-sided, some times 3-sided, inner margins broadly rounded; exposed portions of pistil 0.6-0.8 mm wide; stamens displayed in a well-spaced pattern on all 4 sides of pistil, held just above tepals and persistent; anther 1.3 mm long, 1.8 mm wide, pollen pale orange, oxidising to white. Berries and seed number unknown.
