Mueller, F.J.H. von (1883) Southern Science Record 3 : 176. Type: Near Rockinghams Bay, Dallachy; on the Endeavour River, Persieh.


Vine stem diameters to 8 cm recorded. Dead bark very dark to almost black, finely layered, showing growth rings in transverse section.


Leaf blades about 2.5-6.5 x 1-3 cm, petioles hairy, about 1-4 mm long. Marginal teeth quite small. Stipules hairy, rather narrow, about 1-2 mm long, drawn out into a fine point at the apex. Tendrils are modified branches.


Calyx tube (hypanthium) about 2 mm diam., lobes about 1.5 mm long. Petals absent.


Fruits are conspicuously winged samaras. Fruit + wing about 25-35 mm long, the winged part about 20-23 x 6-7 mm. Wing conspicuously veined with a midrib and lateral veins. Seeds globose, about 3 mm long. Cotyledons about 3 x 3 mm. Radicle straight about 0.4 mm long.


About 4 cataphylls produced before the first true leaves. First pair of true leaves about 10-12 x 5-7 mm, ovate to elliptic, margins toothed. At the tenth leaf stage: leaf blade narrowly ovate, about 17 x 6 mm, petiole less than 0.5 mm long, margin toothed with about five or six teeth on each side. Lateral veins forming definite loops inside the blade margin. Midrib depressed on the upper surface. Stipules caducous, soon turning brown, +/- linear, about 1 mm long. Terminal bud and stem clothed in pale brown hairs. Seed germination time 21 to 22 days.
