SUMMARY
Epiphyte; stems short; internodes short and 0.9-1.2 cm in diam., roots white; cataphylls and old petioles persisting. Cataphylls 5.5-7.5 cm long, persisting semi-intact, heavily tinged reddish, drying brown. Leaves arched with petioles erect-spreading, 14-28 cm long, 2-3.5 mm in diam., slightly thicker than broad, obtusely C-shaped, narrowly and obscurely sulcate, sheathed 0.10-0.25 % of its length, closely ensheathing peduncle, dark green, semi-glossy; sheath 2.2-10 cm long; geniculum sulcate, paler, conspicuously swollen; blades arcuate, 27-59 × 1.9-6.6 cm (averaging 42 × 3.7 cm), oblong-linear to narrowly oblanceolate, stiffly subcoriaceous to coriaceous, occasionally somewhat quilted above, dark green and weakly matte-subvelvety to weakly glossy above, slightly paler and weakly glossy below, narrowly acuminate at apex, narrowly acute at base, with the margins turned somewhat upward; midrib concolourous, bluntly acute at base, more acute and thicker than broad toward apex, sometimes narrowly round-raised toward apex above, narrowly rounded to weakly raised and concolourous to slightly paler than surface below; primary lateral veins weakly raised to narrowly convex and concolourous on upper surface, often pleated-raised and appearing somewhat acute above, scarcely raised on lower surface, only slightly darker than surface, sometimes scarcely visible on either surface; tertiary veins moderately obscure on lower surface; collective veins 1 pair, 3-6 mm from margin, moderately obscure on both surfaces, less conspicuous than primary lateral veins. Inflorescence erect or nearly so at anthesis, becoming spreading, sometimes with the spadix erect; peduncle 17-40 cm long at anthesis (to 50 cm long in fruit); spathe green, 2-3.6 × 6-8 mm, green, tinged reddish purple in age, erect-spreading, often twisted toward apex, sometimes recurled, sometimes arched inward toward spadix; spadix slightly tapered, 5-9 cm long, 3-5 mm in diam., pink, becoming somewhat olive- green, ultimately bright yellow at anthesis. Flowers 5-6 per spiral, 1.8-2.2 mm long and wide, the lateral margins straight to weakly sigmoid; lateral tepals 2-3-sided, 1-1.2 mm wide, weakly glossy; pistils medium green, moderately acute, weakly protruding; stamens held in tight cluster, the anthers contiguous or nearly so. Infructescence spreading-pendent; spadix dark green; berries orange-red, obovoid, 5-7 mm long, 5-6 mm in diam.
