Description
Tree: Height 9-25(-30) m, dbh 22-58 cm (1).Leaves: On primary shoots, nearly imbricate on young plants, spreading and curved forwards on older plants. On foliage shoots distichous and nearly linear (juvenile trees), later losing the distichous habit, becoming wider than thick, keeled on the upper and lower surfaces, spreading with the upper half curving forwards, uniform in size along the shoot, tapering slightly, 1.5-3 × 0.4-0.8 mm or a little larger on younger trees (1).
Cones: Involucral leaves loosely surround the young fertile structure but cover only the receptacle of the mature seed with its covering, which is c. 3-3.5 mm long (1).
Similar species: D. steupii, "which can be distinguished by the form of the foliage and involucral leaves and which, although common to disturbed habitats, usually occupies wet sites" (1).
Range
Restricted to the central highlands of Papua New Guinea, at 1300-2750 m. "Locally common or even in pure stands (e.g. at Wabag), or co-dominant, sometimes emergent, often in disturbed situations, e.g. on edges of treefern grassland, 1300-2750 m" (1).Big Tree
