Blume, C.L. von (1847) Rumphia 3: 207. Type: (not cited).
Cardiopteris lobata var. moluccana (Blume) F.M.Bailey, The Queensland Flora 1: 251(1899), Type: ?.
Stems, petioles and leaves produce a milky exudate. Leaf blade about 6-17 x 5-17 cm, petiole often longer than the leaf blade, about 3.5-17 cm long, shallowly grooved on the upper surface. Usually 3-7 veins, including the midrib, radiate from the base of the leaf blade.
Flowers about 3 mm diam. at anthesis. Sepals about 1-2 mm long, rounded at the apex. Petals fused to form a short corolla tube, corolla about 3 mm long overall. Stamens attached slightly below the apex of the corolla tube. Staminal filaments about 0.5 mm long, anthers bright orange. Ovary +/- globose, about 1 mm diam. Stigmas 2, one terminal on a short style and the other sessile on the ovary.
Fruits 2-winged, about 2.3-2.9 x 1.8 cm, wings about 9-11 mm wide, perianth persistent at the base and style persistent at the apex, style green and fleshy, about 11-13 mm long, resembling two gun barrels. Seeds long and narrow, about 1.6-2.4 cm long. Testa thin, exocarp granular, dry and fibrous. Endosperm spongy, oily. Embryo minute, about 0.4 mm long.
Cotyledons lanceolate, about 22-35 x 7-10 mm. First pair of leaves glabrous, cordate, apex shortly mucronate, base cordate, margin entire except for a few teeth near the base. At the tenth leaf stage: leaves narrowly cordate to sagittate, apex apiculate, base auriculate to sagittate. Petioles twisted, curved near the base. Leaf blades palmately veined, midrib raised on the upper surface. Terminal buds clothed in short translucent hairs but leaves and stems glabrous. Stems twining.
