SUMMARY
Epiphytic; internodes short, 1.5 - 3 cm long; cataphylls 3 - 7 cm long, persisting as dark reddish-brown shredded fibers. LEAVES 45 - 79 cm long (average 61), with petioles 11.7 - 19.1 cm long, (averaging 15.6 cm), 3 - 4 mm diam., nearly terete, narrowly flattened or with narrow, shallowly sulcus adaxially, sheathed 2 cm at base, pale green, weakly glossy, smooth; geniculum 1.5 - 3.2 cm long, 5 - 6 mm wide, 6 - 8 mm thick, not sulcate, slightly darker than petiole; blades linear, to linear-elliptic, pendent from spreading petioles, 33 - 60 cm long (averaging 45.3 cm), 3.7 - 6.3 cm wide (averaging 5 cm), widest near the middle, 5.5 - 7 times longer than wide (fresh blades), 14 - 15 times longer than wide (dried blades shrivel laterally and margins curl under), 2 - 5 times longer than petioles, narrowly acute at apex and at base, dark green and matte and eglandular above, moderately paler and weakly glossy and dark glandular-punctate below, the margins curled under; midrib slightly paler than surface, convex at base, narrowly rounded by middle, becoming bluntly acute toward apex above, thicker, narrowly rounded and moderately paler below; primary lateral veins 7 - 10 pairs, arising at a 15 - 20° angle, weakly sunken and concolorous above, weakly raised, narrowly rounded and slightly darker below; collective veins arising from one of the lowermost pairs of primary lateral veins, more conspicuously sunken than primary lateral veins above, but less so than primary lateral veins below. INFLORESCENCE pendent; spadix nearly 90° pendent from spreading peduncle; spathe 3.7 - 7.3 cm long, 4 - 9 mm wide; immature spadix 3 - 7 cm long, 2 - 3 mm diam., purplish violet; flowers 4 - 5 visible per spiral, 1.6 - 2.5 mm long, 1.4 - 2.2 mm wide; tepals triangular, pinkish tan, glossy, speckled with violet; lateral tepals 1 - 1.5 mm wide, inner margins broadly rounded, outer margins 2 sided; fruiting spadix 20 cm long, 1.5 - 2 cm diam. with berries emergent with tepals faintly purplish, semiglossy, triangular to shield-shaped; inner margin broadly rounded, outer margin 2 - 4 sided. INFRUCTESCENCE: berries white, tinged lavender, lavender at apex at maturity, usually with a purplish cross with weak ridges at apex, 4.2 - 5.2 mm long, 3.2 - 3.5 mm diam.; stigma 0.4mm diam.,oblong-elliptic, borne in a weak depression, mesocarp whitish and mealy; seeds 2 per berry, manila, 1.8 - 2 mm long, 1.1 - 1.3 mm wide, ca. 1 mm thick, enclosed in a translucent envelope.
