CATE Araceae, 17 Dec 2011. araceae.e-monocot.org

Distribution
Sulawesi (Minahassa Peninsular). Endemic.
Diagnostic
Leaf lamina on flowering shoots elliptic-lanceolate to oblong-elliptic, stiffly coriaceous, base cuneate, apex acuminate to attenuate with a prominent tubule. Sulawesi (endemic) Superficially similar to the widespread R. montana, Bornean R. elliptica Ridl. and R. elliptifolia Merr., but readily distinguished by the prominently stipitate spadix, raised stigma, the smaller, elliptic-lanceolate to oblong-elliptic, stiffly coriaceous leaves with (in dried material) more prominently raised primary venation and the fibrous cataphyll remains subtending the inflorescence.
General Description
Slender, leptocaul, homeophyllous (?) liane to unknown ultimate height; seedling and pre-adult plants not observed; adult shoot architecture comprised (?) of greatly elongated, clinging, physiognomically monopodial, leafy, non-flowering stems and long moderately elaborated, free, sympodial, densely leafy, flowering stems; stems smooth, flexuous, climbing stems not observed, free stems terete in cross-section, with weak prophyll, cataphyll and petiolar sheath fibre, internodes to 2 x 0.7-0.8 cm on free shoots; LEAVES weakly distichous; cataphylls and prophylls membranous, very quickly drying and degrading to weak fibres and sheets of tissue; petiole weakly canaliculate, 7-10 x 0.15-0.3 cm, smooth, with a slight apical and prominent basal geniculum; petiolar sheath very prominent, extending beyond the apical geniculum by two very small ligules, swiftly drying and degrading into weak fibre and soft strips, eventually falling to leave a continuous scar from the petiole base, around the top of the apical geniculum and back to the base; lamina entire, elliptic-lanceolate to oblong-elliptic, stiffly coriaceous, 7-20 x 3--6 cm, base cuneate, apex acuminate to attenuate with a prominent tubule; midrib raised abaxially, slightly sunken adaxially; primary venation pinnate, slightly raised on both surfaces; interprimaries subparallel to and about as prominent as primaries; secondary venation ± invisible in dried specimens; INFLORESCENCE solitary, subtended by a fully developed foliage leaf; peduncle slightly compressed-cylindric, 4-12 x 0.2-0.3 cm; spathe narrowly boat-shaped, stoutly long-beaked, c. 10 x 1.6 cm, coriaceous, falling to leave a large, straight, scar; spadix slender cylindrical, 5-6 x c. 0.7 cm, stipitate; stipe 1.1-1.3 x c. 0.15 cm; stylar region rather well developed, mostly rhombohexagonal, c. 1 x 1.2 mm, conical; stigma punctiform, c. 0.3 mm diam.; anthers exserted at anthesis; INFRUCTESCENCE oblong-cylindric, 5.5-9 x 1.5-1.7 cm.
