SUMMARY
Moderate to large, rather robust, semi-pachycaul homeophyllous liane to 5 m; seedling stage not observed; pre-adult plants often forming small terrestrial colonies; LEAVES: adult shoot architecture comprised of elongated, clinging, physiognomically monopodial, leafy, non-flowering stems and short, usually unbranched, free, sympodial, densely leafy, flowering stems; stems smooth, terete in cross section, with very sparse prophyll, cataphyll and petiolar sheath fibre, this soon falling, internodes to 13 x 1.5 cm on adherent shoots, usually shorter and stouter on free shoots, separated by large, straight, corky leaf scars, older stems woody; flagellate foraging stems absent; clasping roots sparsely arising from the nodes and internodes of clinging stems, pubescent; feeding roots rare, adherent, pubescent; leaves distichous on adherent and free shoots; cataphylls and prophylls membranous, quickly drying and degrading into very sparse fibres, these soon falling; petiole deeply grooved to basally canaliculate, 9-33 x 0.2-3 cm, with the distal portion and apical geniculum minutely pubescent, especially when newly expanded, apical and basal geniculum moderately prominent; petiolar sheath very prominent, extending to just below the apical geniculum, swiftly drying and degrading into sparse, soon-falling; lamina entire to slightly perforated, perforations round to rhombic, extending c.c. 1/5-1/4 of lamina width on each side of the midrib, ovate to oblong-lanceolate or oblong-elliptic, oblique to falcate, minutely pubescent abaxially when young, 8-34 x 3.5-10.5 cm, thinly coriaceous to sub-chartaceous, base unequal, rounded, acute to slightly decurrent, apex acute to acuminate; mid-rib prominently raised and pubescent abaxially, ± sunken adaxially; primary venation pinnate, slightly raised abaxially and adaxially, the leaf appearing slightly quilted, pubescent in younger leaves, indumentum mostly shed in older leaves; interprimaries sub-parallel to primaries, very slightly less prominent, slightly raised abaxially, slightly impressed adaxially; secondary venation tessellate to weakly reticulate, slightly raised; tertiary venation not visible; INFLORESCENCE solitary, very rarely two together, fragrant of frangipani and pineapple (fide Hay et al. 9029) subtended by a fully developed foliage leaf and, if more than one inflorescence, then second preceded by a large cataphyll; peduncle strongly compressed-cylindric, 4-9 x 0.4-0.6 cm; spathe canoe-shaped, stoutly long-beaked, 5.5-19 x 1-6.5 cm, stiff-fleshy, dull green to dull yellow, pale yellow internally, falling (after?) female receptivity to leave a large, straight scar; spadix very weakly clavate cylindrical, sometimes slightly curved, sessile, inserted ± level on peduncle, 3-11.5 x 1-1.6 cm, cream; stylar region mostly hexagonal, 1.5-2 x 2.1-2.5 mm, truncate; stigma punctiform, prominent, 0.5-0.75 x 0.45-0.75 mm; anthers exserted at anthesis; INFRUCTESCENCE stoutly oblong-cylindrical, 4.5-14 x 1.5-2 cm.
