Family

Forster, P.I. (2005) Austrobaileya 7: 91. Type: Queensland, Millaa Millaa Falls, 23 June 1997, P.I Forster PIF 21249. Holo: BRI. Iso: DMA, MEL, NSW.

Stem

Usually flowers and fruits as a shrub about 1-3 m tall, sometimes flowers when smaller.

Leaves

Leaf blades about 5-8 x 2.5-3.5 cm, petioles about 0.2-0.5 cm long. Lateral veins about 5-12 on each side of the midrib. Stipules small, less than 1 mm long. Terminal buds enclosed in a number of bracts or scales. Leaves alternate but often arranged in whorl-like clusters or in pairs.

Flowers

Male flowers: Flowers about 5 mm diam., pedicels about 4-6 mm long. Anthers about 4-5, about 0.5 mm wide, filaments about 2 mm long. A large flat disc surrounds the rudimentary ovary which has a tuft of brown hairs at the apex. Female flowers: Flowers pedicels about 7-15 mm long, a large flat disc surrounds the ovary. Ovary about 1 mm diam. Stigmas three, each bilobed at the apex.

Fruit

Capsules depressed globular, about 12 x 18 cm, disintegrating completely at maturity. Tepals persistent at the base and styles at the apex. Pedicels about 25 mm long. Seeds about 2-4 per fruit. Seeds angular, about 9 mm long. Cotyledons folded many times.

Seedlings

Cotyledons +/- orbicular, about 25 x 20-27 mm, base cordate, apex rounded. First pair of leaves elliptic, margins smooth, midrib raised on the upper surface. At the tenth leaf stage: leaf blades obovate, very attenuate at the base, lateral veins forming loops inside the blade margin. Stipules brown, broadly triangular, about 1 mm long or less. Terminal bud enclosed in overlapping bracts. Cotyledons usually still present at the tenth leaf stage. Seed germination time 16 to 387 days.

Distribution and Ecology

Endemic to NEQ, known only from collections made at a few sites on the Atherton Tableland. Altitudinal range from 600-800 m. Grows as an understory plant in well developed upland rain forest.
