General Description
Large, robust, pachycaul (?), homeophyllous liane to unknown ultimate height; seedling stage not observed; pre-adult plants consisting of sparse terrestrial colonies; LEAVES: adult shoot comprised of elongated, clinging, physiognomically unbranched, non-flowering stems and free lateral, leafy flowering stems; stems with cataphylls and prophylls degrading to long sparse ragged fibres and weak sheets of tissue, internodes 0.5-3 x 0.5-2 cm, separated by prominent to very large unevenly oblique corky leaf scars; flagellate foraging stem and clasping roots not observed; feeding roots stout, arising singly from the node, densely velvety-hairy; leaves spiro-distichous; cataphylls and prophylls quickly degrading to long sparse ragged fibres and weak sheets of tissue; petiole canaliculate, 6-46.5 x 1.3-1.5 cm, apical geniculum very large, prominent, basal geniculum very weakly defined; petiolar sheath very prominent, extending to apical geniculum, swiftly degrading to long ragged fibres and weak sheets of tissue, later falling leaving a jagged scar; lamina entire, ovate to oblong-elliptic or oblong-ovate, strongly oblique, 8-53 x 6-26 cm, submembranous, drying discolorous, adaxially dark brown, densely faint dark speckled, abaxially greenish brown, base oblique, one side rounded to almost truncate, other subacute, apex subacute to acuminate or briefly attenuate; midrib very prominently raised abaxially, slightly sunken adaxially; primary venation pinnate, prominently raised abaxially, very slightly raised adaxially, drying paler than lamina; interprimaries parallel to primaries, much less prominent, slightly raised abaxially, very slightly raised adaxially; secondary venation parallel to interprimaries and only slightly less prominent, very slightly raised abaxially and adaxially; tertiary venation reticulate, weakly raised abaxially, invisible abaxially; INFLORESCENCE solitary, subtended by a ± fully developed foliage leaf and one or more degrading papery cataphylls; peduncle laterally compressed, stout, 13-15 x 0.7-1 cm; spathe slender canoe-shaped, 22 x 4 cm, stoutly long-beaked, caducous before male anthesis, falling leaving a large scar; spadix stoutly cylindrical, sessile, inserted more or less level on peduncle, 17-19 x 1.5-2 cm, yellow green; stylar region hexagonal, 1.5-2 x 1.2-1.5 mm, truncate; stigma punctiform to slightly ellipsoid, very slightly raised, 0.4 x 0.4-0.5 mm diam.; anthers long-exserted at male anthesis; INFRUCTESCENCE not observed.
Habitat
Primary and secondary riverine rain forest.
Distribution
Papua New Guinea (East Sepik and Morobe Prov.), Bougainville.
Diagnostic
Easily confused with Rhaphidophora intonsa (also with large inflorescences and fibrous shoot tips) but separated by the simple, not netted, fibres, thinner-textured leaf lamina with, on the abaxial surface, a conspicuously raised midrib and much more pronounced differentiation between the primary lateral and interprimary veins, and by the long-exserted anthers.

Native to:

New Guinea
