Rhaphidophora sylvestris

<p>Medium to large, occasionally very large, moderately robust, leptocaul to semi-pachycaul homeophyllous liane to 20 m; seedling stage a non-skototropic shingling shoot; pre-adult plants very seldom forming small terrestrial colonies of shingling shoots; LEAVES: adult shoot architecture comprised of greatly elongated, clinging, physiognomically monopodial, leafy, non-flowering stems and long, moderately elaborated, free, sympodial, densely leafy, flowering stems later pendent under their own weight; stems smooth, climbing stems rectangular in cross section, the angles often slightly winged, the surfaces between slightly concave, free stems rectangular to sub-terete in cross-section, green, later mid-brown, without prophyll, cataphyll and petiolar sheath fibre, internodes to 2.5 - 5 x 0.5-1 cm on adherent shoots, usually less stout on free shoots, separated by weakly defined, slightly oblique leaf scars, older stems woody; flagellate foraging stems frequent, often of great length, ± rectangular in cross section; clasping roots densely arising from the nodes and internodes of clinging stems, pubescent; feeding roots very rare, adherent, pubescent; leaves distichous on adherent and free shoots, those distal on flowering shoots densely so; cataphylls and prophylls membranous, very quickly drying and falling; petiole deeply grooved adaxially, 1-8.5 x 0.15-0.3 cm, smooth, apical and basal genicula weakly defined; petiolar sheath very prominent, extending to and encircling the apical geniculum, briefly ligulate, very swiftly drying and falling to leave a continuous conspicuous scar from the petiole base, around the top of the apical geniculum and back to the base; lamina entire, lanceolate-elliptic to falcate-lanceolate, slightly to markedly oblique, 4.5-32 x 1.75-8.5 cm, thinly coriaceous, upper surfaces slightly glossy, lower surfaces semi-matte, base sub-acute to briefly truncate, apex acute to slightly attenuate, with a prominent apiculate tubule; mid-rib slightly raised abaxially, slightly sunken adaxially; primary venation pinnate, slightly raised abaxially and adaxially; interprimaries parallel to primaries and only slightly less prominent, very slightly raised abaxially and adaxially; secondary and tertiary venation ± obscure in fresh material, visible as a faint reticulum in dried specimens; INFLORESCENCE solitary, subtended by a fully developed foliage; peduncle compressed-cylindric, 2-8.5 x 0.15-0.5 cm; spathe cigar-shaped, stoutly very short-beaked, 4.5-7.5 x 1-3 cm, thinly stiff-fleshy, dull yellow, paler internally, swiftly falling at female receptivity; spadix weakly clavate-cylindrical, sessile, inserted ± level on peduncle, 3-6 x 1-2.5 cm; stylar region, mostly rhombohexagonal, 1-2 x 1.5-2 mm, truncate; stigma punctiform, raised, c.c. 0.25-0.3 mm diam.; anthers exserted at anthesis; INFRUCTESCENCE 6-8 x 2-2.5 cm.</p>
