A specimen from Kew's Herbarium


CATE Araceae, 17 Dec 2011.

Very similar to R. perkinsiae but distinguished by the stiffer, smaller leaves, the denser primary lateral and interprimary venation, the wide ligulate petiolar sheath, the semi-persistent cataphylls at the active shoot tips and the prominent cylindrical style.
General Description
Moderately robust, semipachycaul homeophyllous liane to 4 m; seedling stage and pre-adult plants not observed; LEAVES: adult shoot architecture comprised of elongated, clinging, physiognomically monopodial, leafy, non-flowering stems and shorter, clinging, sympodial, densely leafy, flowering stems; stems smooth, terete in cross-section, with briefly persistent cataphyll remains at the apices of active shoots, internodes to 6 x 1 cm on adherent shoots, usually shorter and less stout on free shoots, drying very dark brown, separated by large oblique leaf scars; flagellate foraging stems not observed; clasping roots densely arising from the nodes and internodes of stems, pubescent; feeding roots not observed; leaves distichous; cataphylls and prophylls large and conspicuous, membranous, very quickly drying and falling; petiole deeply channelled adaxially, 5-11 x 0.2-0.3 cm, smooth, apical and basal genicula weakly defined; petiolar sheath very prominent, extending to overtopping the apical geniculum, ligulate, clasping the newly emerged leaf or inflorescence, swiftly drying and soon falling whole to leave a conspicuous scar; lamina entire, oblong to oblong-lanceolate, slightly oblique, 6-23 x 2-8 cm, coriaceous to stiffly coriaceous, drying discolorous, base subacute, apex caudate-acuminate with a slightly prominent apiculate tubule; midrib raised abaxially, slightly sunken adaxially; primary venation densely pinnate, slightly raised abaxially and adaxially; interprimaries parallel to primaries and only slightly less prominent, very slightly raised abaxially and adaxially; secondary venation ± obscure in fresh material, visible as a faint reticulum in dried specimens; INFLORESCENCE solitary, subtended by a fully developed foliage leaf and several degraded cataphylls; peduncle slightly compressed-cylindric, 7-26 x 0.3-0.6 cm; spathe canoe-shaped, stoutly short-beaked, 8-14 x 1.2-5 cm, stiff-fleshy, green, falling (at female receptivity ?); spadix cylindrical, sessile, inserted obliquely on peduncle, 5-12 x 1-2 cm, white; stylar region weakly rhombohexagonal, often barely angled, 0.9-1.2 x 1-1.1 mm, weakly conical; stigma cylindrical, raised, c. 0.2 mm diam.; anthers strongly exserted at anthesis; INFRUCTESCENCE 10-17 x 2-4 cm.
