About 4 cataphylls produced before the first pair of true leaves. First pair of true leaves about 5.2-8.5 x 2.4-3.5 cm, petioles about 4 mm long, deeply grooved on the upper surface. Oil dots numerous and closely packed. At the tenth leaf stage: leaf blade about 7-7.5 x 2-3 cm. Lateral veins about 25-30 on each side extending from the midrib to the intramarginal vein. Petiole about 0.5 cm long, deeply grooved on the upper surface. Seed germination time 36 days.

Distribution and Ecology

Possibly endemic, occurs in NEQ, known only from a few collections in the Mt Poverty area on the upper reaches of the East Normanby River and also from the Rossville area. Altitudinal range not known but collections made at an elevation of 200-600 m. Grows in rain forest often along creeks.
