Cooper, W.E. (2013) Austrobaileya 9(1): 10-12. Type: Australia: Queensland, Cook District: about 3 km N of 3-ways, Iron Range National Park, 29 July 2013, W.Cooper 2225, C.Zdenek, B.Venables & J.Pritchard (holo: CNS [2 sheets + spirit]; iso: A, BRI, CANB, FRI, K, KEP, KL, MEL, MO, NSW, NY, SING, US).


Shrub or tree to 15 m, seldom exceeding 15 cm dbh. Exudate white or colourless. Dioecious.


Petioles and twigs produce clear exudate. Petioles 5-7 mm. Leaf blades 5.2-16 cm long x 2.0-7.2 cm wide; narrowly to broadly elliptic, ovate-elliptic or obovate. Secondary veins 7-10 pairs. Latex canals on the underside of the leaf blade resemble veins but run at such an angle as to be incompatible with the normal veins.


Male inflorescence axillary, a fascicle or raceme, 5-many-flowered. Male flowers: 7-8 mm diam., pedicels 4.5-12 mm long; sepals 4, 2-whorled, outer pair joined, D-shaped, 1.6 mm long x 1.8 mm wide; inner pair free, petal-like, ca. 4 mm long x 3 mm wide; petals 4, free, imbricate, ca. 4 mm long x 3-4 mm wide; androecium 4-phalangiate, phalanges 3.2 mm long x 2-3 mm wide, apex divided into 2-7 short filaments; anthers 15-30 per phalange. Female inflorescence: terminal or axillary, supra-axillary or ramiflorous, a solitary flower, fascicle or condensed raceme, 3-9-flowered. Female flowers: 4.5-6.5 mm diam.; pedicels 3.5-4.5 mm long; sepals 4, 2-whorled, D-shaped; outer pair joined, ca. 1 mm long x 2 mm wide; inner pair free, 1.2-2 mm long x 2-3 mm wide; petals 4, free, 2 mm long x 2-3 mm wide; gynoecium fungiform, unlobed; stigma disklike, entire, 2.5 mm diam.


Fruits a fleshy berry, globose to depressed globular, often laterally compressed, 12.5-15.5 mm long x 11-160 mm wide. Calyx lobes four, persistent. Stigma persistent. Seeds 1 or 2, about 10 mm long x 5 mm wide.


At the tenth leaf stage: leaves obovate, apex acute, glabrous on both the upper and lower surfaces, undersurface with a network of fine almost parallel latex canals; small glands on the stem opposite the base of the petiole. Seed germination time 50 days.

Distribution and Ecology

Occurs in CYP, known from the Torres Strait islands to the McIlwraith Range. Altitudinal range small, from sea level to about 500 m. Grows as an understorey tree in well developed rain forest or gallery forest on river banks.
