CATE Araceae, 17 Dec 2011.

Widespread from Papua New Guinea (including Bismarck Archipelago) to the Solomon Islands.
General Description
Slender to moderately robust, leptocaul, homeophyllous (?) liane to 20 m; seedling and pre-adult plants not observed; LEAVES: adult shoot architecture comprised of elongated, clinging, physiognomically unbranched, leafy, non-flowering stems and very short to somewhat lengthened, unbranched, free, sympodial, leafy, flowering stems; stems smooth, flexuous, terete, without prophyll, cataphyll and petiolar sheath fibre, internodes 1-9 x 0.5-1.5 cm, separated by thin, slightly oblique, leaf scars, older stems woody; flagellate foraging stems absent; clasping roots arising singly from the node; feeding roots not observed; leaves spiro-distichous, scattered; cataphylls and prophylls membranous, caducous; petiole grooved adaxially, 7-14 x 0.2-0.3 cm, smooth, with a very slight apical and prominent basal geniculum; petiolar sheath very prominent on newest leaves, very broad basally, narrowing c. 1/2 way along petiole and extending beyond the apical geniculum by two tiny ligules, caducous leaving a continuous scar from the petiole base, around the top of the apical geniculum and back to the base; lamina entire, lanceolate to oblong-lanceolate, slightly to prominently oblique, 10-34 x 4-9.5 cm, thinly coriaceous, base obtuse-cuneate to rounded and minutely cordate, apex falcate, acute to long-acuminate, with a tiny tubule; midrib slightly raised abaxially, flush to very slightly sunken adaxially; primary venation pinnate, slightly raised on both surfaces; interprimaries sub-parallel and barely less distinctive than primaries; secondary and tertiary venation reticulate, conspicuous in dry material; INFLORESCENCE solitary, subtended by a incompletely developed foliage leaf and one or more prominent caducous cataphylls; peduncle slightly compressed-terete, 5-9 x c 0.5-1 cm; spathe cigar-shaped, apex stoutly beaked, 4-11 x c. 3.5 cm (flattened out), thick, marcescent, falling as fruits ripen, green at male anthesis; spadix cylindrical, stipitate, inserted slightly obliquely on stipe, 6-8.5 x 1.5-2 cm, creamy white; stipe terete, 0.5-1 cm long; stylar region depressed-rhombohexagonal, c. 1.2 x 1.3 mm, truncate; stigma punctiform, c. 0.3 mm diam., raised at male anthesis but barely prominent in dried material; anthers strongly exserted at male anthesis; INFRUCTESCENCE stoutly cylindrical, c. 8 x 3 cm, with dry spathe persisting.
Primary to disturbed secondary broadleaf and coniferous (Araucaria) forest on humus, alluvium and lava.
In most of its medium to large manifestations R. schlechteri is similar in overall appearance to R. mima, but is distinguishable by the marcescent spathe and stipitate spadix. Small forms of R. schlechteri maybe confused with R. neoguineensis , although the globose spathe and sessile ellipsoid spadix readily distinguish the latter.

Native to:

Bismarck Archipelago, New Guinea, Solomon Is.
