Characteristics

Shrub to tree, 2-36 m tall, up to 70 cm diam. Juvenile leaves spreading widely, bent slightly forward, linear-lanceolate, up to 2 cm long, 0.8 mm wide, strongly keeled on the dorsal side, slightly keeled and slightly convex on the axial side, about 0.2 mm thick, apiculate. Adult leaves spreading widely, straight or slightly bent forward but the tips still directed outwards, lanceolate to linear-lanceolate, 6-10 mm long or shorter at the base of the shoot, apiculate, strongly keeled on the dorsal side, slightly keeled and slightly concave on the axial side, 0.5-0.8 mm wide, 0.2 mm thick. Fertile structures both terminal and lateral. Pollen cone subtended by a cluster of reduced leaves which are c. 2 mm long, cone 5-13 mm long and 2-2.5 mm diam.; apex of the microsporophyll a lanceolate spur 0.6-1.2 mm long and 0.3 mm wide at the base. Seed-bearing structure subtended by a shoot up to 4 mm long with reduced leaves c. 2 mm long or when terminal sometimes following normal leaves; fertile bracts similar to leaves, spreading, 2-3 mm long; the shiny brown seeds c. 4 mm long, fully exposed, often in pairs.
