George, A.S. & Hyland, B.P.M. (1995) Flora of Australia 16: 497. Type: Branch of Cooper Creek, Qld; 16 10S, 145 24E, 22 Aug. 1987, G.Sankowsky 638 & N.Sankowsky.
Oak grain in the wood and a corresponding pattern in the inner blaze.
Oak grain in the twigs. Leaf blades about 8-23 x 2.5-6 cm. Petioles absent or very short and swollen at their junction with the twig. Midrib raised on the upper surface of the leaf blade. Lateral veins forming loops well inside the blade margin.
Flowers paired, pedicels about 6-7 mm, common peduncle absent or very short. Tepals glabrous on the outer surface, about 20-25 mm long. Hypogynous glands fused to form a cup, lobed at the apex and usually open on one side. Ovary sessile, glabrous, ovules 2.
Cotyledons +/- obovate, about 17-20 mm long. First leaf coarsely toothed or lobed, subsequent leaves with serrate margins. At the tenth leaf stage: leaf blade +/- elliptic, sessile, base amplexicaul, margin serrate towards the apex but smooth towards the base; terminal bud clothed in rusty red, prostrate hairs.
Distribution and Ecology
Endemic to NEQ, known only from Noah Creek, Mt Sorrow, Mt Hemmant, Pieter Botte Logging Area and Roaring Meg Creek. Altitudinal range from near sea level to 700 m. Grows as an understory tree in well developed lowland rain forest but is probably more frequently encountered in fringing forest along creeks and watercourses.
Shrub (woody or herbaceous, 1-6 m tall)
