4. Epipremnum moluccanum Schott
Epipremnum mollucanum Schott, Ann. Mus. Bot. Lugd.-Bat. 1: 130 (1863). -- [Dracontium moluccanum Zipp. ex Schott Ann. Mus. Bot. Lugd.-Bat. 1: 130 (1863), nom. superfl.]. --Type: Indonesia, Maluku, Pulau Ambon, Zippelius 59d (L holo).

Large root-climber. Adult plant with stem c. 7 mm diam., epidermis minutely asperous, internodes c. 3.5 cm long, separated by prominent leaf scars furnished with a narrow collar of sheath tissue. Foraging shoots occurring (fide Zippelius ex Schott, 1863: 130). Cataphylls and prophylls soon drying and falling. Petiole 18--21 cm x 7--10 mm, canaliculate, smooth, air-drying pale brown; apical geniculum rather prominent, 7--10 x 3--4 mm, basal geniculum 3.5 x 1 cm, both genicula drying shrunken to less than petiole diameter; petiolar sheath very prominent, extending to the along the adaxial surface of the geniculum and ± merging with lamina margins, margins somewhat ragged, base of sheath ± enclosing the stem. Lamina 21.5--24 x 10.2--10.5, entire, elliptic to slightly oblique-elliptic, apex acute to slightly attenuate, base acute to sub-obtuse, briefly decurrent, air-drying mid-brown; primary lateral veins simple, 6--9 per side, c. 2 cm distant, diverging from midrib at c. 45°, barely differentiated from interprimary veins, interprimary veins remaining parallel to primary veins, all higher order venation tesellate, but barely visible in dried material; midrib moderately impressed above, prominently raised beneath, lower order venation flush or nearly so above and beneath in fresh material but raised and rather conspicuous in dried specimens. Inflorescence solitary, subtended by a fully developed foliage leaf with a much expanded petiolar sheath. Peduncle 4.3 x 5 mm, sub-terete, epidermis slightly rough. Spathe canoe-shaped, exterior and interior dull yellow. Spadix stipitate, fertile portion cylindrical, apex rounded, obliquely inserted on stipe; stipe 10 x 6 mm, obliquely inserted on peduncle. Flowers 2--2.5 mm diam.; stamens 4; filaments 5 x 1 mm; anthers narrowly ovoid, 3--5 x 0.75--1 mm; ovary 7--9 x 2.5--4 mm, cylindrical, basal part laterally compressed; ovules 2; stylar region c. 2.2 x 2 mm, trapezoid in air-dried post-anthesis material, somewhat feeble, apex flattened, margins slightly raised in dry material; stigma elongate-globose, c. 1.5 mm x 0.5, circumferential, very slightly prominent. Fruit green, stylar region somewhat feeble.
Distribution - Indonesia (Maluku).
Habitat - Unclear. ‘In montanis supra arbores’ fide Schott.
Note - Known only from the type gathering, E. moluccanum is a distinctive species with broad elliptic leaf laminae and a stipitate spadix. While the leaf shape is unique, the character of a stipitate spadix is shared with E. papuanum Alderw. (New Guinea).
