Distribution

NE. Queensland (incl. Thursday I., Fitzroy I.) and East Malesia: New Guinea and the Aru Is. (Trangan and Wokam Is.). .
Notes
The phyllotaxis is not constant, several specimens have whorls of 3, reminding of D. bancana with which this species is closest related. In 3 m high saplings (DOCTERS VAN LEEUWEN n. 38, cultivated in Hort. Bog. sub XVI.I.F.8) all leaves were opposite.
Similarly saplings in Queensland may have opposite leaves and, moreover, narrow oblong to lanceolate leaves with wavy, even toothed margin (L. S. SMITH 12382). Such plants were described as D. hirsuta and may precociously flower; also very small normal-leaved specimens may flower, obviously at an early age, in New Guinea, possibly stimulated by open, pyrogenous habitat. Such specimens may also sucker.
