Amydrium medium (Zoll. & Moritzi) Nicolson

Evergreen, medium-sized, somewhat robust, hemiepiphytic lianes to 10 m. Stem (adult) root-climbing, producing long flagelliform shoots with reduced cataphylls and scattered foliage leaves. Leaves remote from one another, the nodes between foliage leaves bearing papery cataphylls, although foliage leaves a few together at the tips of stems; petiole 15 – 35 cm, pulvinate apically and basally; petiolar sheath very short, barely exceeding the basal pulvinus; leaf blade (adult) ovate-cordate or pandurate–trilobed, 12–45 × 9–25 cm, largest leaves with several to many round to oval perforations near midrib, (juvenile) entire to once or twice perforated, rarely pinnatisect; deep glossy green to markedly greyish or strkingly bluish; primary lateral veins pinnate, running into marginal vein; higher order venation wholly reticulate. Inflorescence 1–several in each floral sympodium; peduncle erect, much shorter than petiole, 4–10 cm, subtended by several membranous, later papery cataphylls; spathe conchiform to ovate, apiculate, reflexed at anthesis and then caducous, very occasionally marcescent, ca 9 × 7 cm, white; spadix stipitate, ca 4–6 × 1 cm, white to cream, stipe obliquely inserted onto spadix, 0.5 cm, green; gynoecium obpyramidal or obconoid, tetragonal; stylar region broader than ovary, ca 3.5 × 2 mm, slightly prominent centrally below stigma, otherwise ± truncate; stigma small, hemispherical to transverse-linear. Infructescence comprising individual subglobose berries, these ca 1 cm diam., domed at apex, ripening white.
