General Description
Small but robust pachycaul, homeophyllous (?) liane to unknown ultimate height; seedling stage not observed; pre-adult plants climbing with leaves arranged in two ranks and distinctive by the conspicuous yellow chartaceous petiolar sheaths; adult shoot architecture comprised of clinging, physiognomically unbranched, densely leafy flowering stems; stems with conspicuous smooth papery epidermis and cataphylls and prophylls persistent and drying dark yellow, then degrading into parchment-like remains and fibres, internodes 1-2.5 x 0.3-0.9 cm, separated by almost straight leaf scars; flagellate foraging stem absent; clasping roots densely arising from the nodes and internodes, minutely pubescent; feeding roots not observed; LEAVES distichous; cataphylls and prophylls thinly but stiffly chartaceous, eventually degrading into strips of tissue and fibres, particularly at tips of flowering shoots; petiole deeply canaliculate, 3-15 x 0.2-0.4 cm, smooth, apical geniculum weakly prominent, basal geniculum slightly less so and mostly obscured by cataphyll remains; petiolar sheath extending to apical geniculum, persistent, eventually degrading in strips leaving fibres; lamina entire, lanceolate to elliptic, falcate, 6-23 x 1.5-5 cm, stiffly coriaceous, apex acute, briefly acuminate; midrib raised abaxially, sunken adaxially; primary venation pinnate, raised abaxially, slightly less raised adaxially; interprimaries sub-parallel to primaries and less conspicuous; secondary venation tessellate-reticulate, raised abaxially, nearly flush abaxially; tertiary venation similar to secondary venation although more or less invisible; INFLORESCENCE several together, each subtended by a prominent chartaceous prophyll and one or more chartaceous cataphylls, the entire synflorescence emerging from a mass of cataphyll remains; peduncle stout, terete to laterally compressed, obscured by cataphylls, 2-4 x 0.3-0.35 cm; spathe canoe-shaped, slightly stoutly beaked, 4-5.5 x 1.5-2 cm, stiff-fleshy, duration unknown; spadix cylindrical, stipitate, c. 3.2 x 0.9 cm, cream; stipe 2-3 mm; stylar region rounded-conical, almost circular in plan view, 0.25-0.4 mm diam.; stigma deeply excavated, c. 0.2 mm diam; anthers not exserted at male anthesis; INFRUCTESCENCE not observed.
Stunted forest and mixed heath forest on steep slopes.
Indonesian Papua (Mimika Prov.) and Papua New Guinea (East Sepik Prov.).
Based on inflorescence presentation, Rhaphidophora waria is close to R. spathacea but differs in the smaller, narrower, much stiffer leaf laminas with the primary lateral and interprimary veins clearly differentiated from one another, the stipitate spadix and the deeply excavated stigmas.
