Pothoidium lobbianum Schott

Slender to robust, high root-climbing liane. Shoot system well-differentiated into adherent, climbing shoots and free, lateral flowering branches; eocaul not observed; seedling with congested leaves similar in shape to adult, but with blade elliptic and as long as petiole, becoming progressively larger as shoot extends. LEaVES mid-green above, slightly paler below, drying variously dull green to orange-brown; petiole 4–17.5 × 0.4–2 cm, greatly exceeding the blade in length, oblanceolate, distally rounded to truncate to auriculate; blade (0–)1–6 × 0.3–1.5 cm, elliptic to narrowly triangularlanceolate,somewhat acute, base rounded to truncate; primary lateral veins very obscure, diverging at c. 30–40°, intramarginal veins nearly invisible, 2 (or 3) on each side of the midrib. INFLORESCENCES several to many, borne in a terminal branching system on either the primary or subsidiary (in which instance primary inflorescence system often accompanied by two or more subsidiary systems) tips of long pendent shoots, branching system 9–41 cm in total length, lower inflorescences axillary to a foliage leaf, upper ones either subtended by a cataphyll or without a subtending leaf; peduncular axis slender to very stout, composed of one to several internodes, sometimes subtended by a prophyll, sometimes also bearing a cataphyll ± halfway up; peduncle slender, 1–2 cm long. Spathe 2–3 × 0.2–0.4 cm, + lorate-lanceolate, spreading to slightly reflexed, greenish white. Spadix long stipitate to sessile; stipe 0–3.5 cm long; fertile portion 1–6 × 0.2–0.4 cm, slender to rather stoutly cylindrical, pale green. Flowers c. 1.3 mm diam., with 6 free tepals and 6 stamens. INFRUCTESCENCES with many berries; fruit 0.8–1.1 × 0.5–1 cm, globose-oblong to obovoid, bright red when ripe; seeds ellipsoid, c. 1 cm × 6 mm, mid-brown.
