CATE Araceae, 17 Dec 2011.

Potentially confusable with R. oligosperma (Maluku) but immediately distinguished by the much narrower, strongly falcate leaves, the sessile spadix and conical style.
General Description
Moderate, robust, semipachycaul, homeophyllous (?) liane (?) to unknown ultimate height; seedling stage and pre-adult plants not observed; LEAVES: adult shoot architecture not fully known but seemingly comprised of clinging, physiognomically, non-flowering stems and shorter clinging, sympodial, densely leafy, flowering stems; stems drying deeply longitudinally ridged, internodes on flowering stems 2-3 x c. 1 cm, separated by prominent straight to slightly oblique leaf scars; clasping roots densely arising from the nodes, pubescent; feeding roots, unknown; leaves distichous in specimen seen; cataphylls and prophylls chartaceous, soon falling; petiole deeply canaliculate, 14-31 x 0.3-0.4 cm, apical and basal geniculum prominent; petiolar sheath prominent, extending to apical geniculum, ± short-persistent, degrading to chartaceous strips and a few weak fibres; lamina entire, narrowly falcate-lanceolate to narrowly falcate-oblanceolate, oblique, drying distinctly discolorous, dark brown above, orange-brown below, 32-46 x 4.5-7 cm, weakly coriaceous, base rounded, decurrent, apex acute with a prominent apical tubule; midrib prominently raised abaxially, ± sunken adaxially; primary venation densely pinnate, raised abaxially, slightly raised adaxially; interprimaries parallel to primaries and barely less prominent; secondary venation reticulate, very slightly raised; INFLORESCENCE subtended by a large chartaceous cataphylls, these swiftly degrading, and falling; peduncle slightly compressed, distinctly enlarged distally towards spathe insertion, 10.5-11 x 0.3-0.5 cm; spathe unknown, falling to leave a large scar at the base of the spadix; spadix slightly tapering-cylindrical, sessile, obliquely inserted on peduncle, 5 x 1 cm in the single collection known; stylar region moderately developed, rounded-trapezoid to weakly rhombohexagonal, c. 1 x 1.5 mm, shortly conical; stigma punctiform, raised, c. 0.3 mm diam.; anthers not exserted at anthesis; INFRUCTESCENCE unknown.
