Agathis robusta (C. Moore ex F. Muell.) F.M. Bailey

An introduced evergreen tree, native to Australia

Monoecious trees 25-30(-43) m tall and 100-150(-200) cm dbh; trunk straight with little taper, clear for over half its length; crown dense (Newbury [no date]). Bark orange-brown, brown or grey-brown; smooth to slightly flaky. Inner bark mixed red, pink and brown; bark exudate clear or somewhat milky (Boland et al. 1985). Shoots of two types, primary (from the branch) and lateral, diverging from primary shoots. Leaves spirally arranged on primary shoots, opposite to subopposite on lateral shoots; leaves entire on petioles 3-10 mm long, linear to elliptic, 5-13 × 1-4 cm, stiff; veins fine, longitudinal, more or less parallel. Juvenile leaves similar but oblong-lanceolate, acute, 6-7 × 1-2 cm, glabrous, green, shiny above and dull beneath, venation faint and longitudinal. Cotyledons 2, almost sessile, oblong or ovate, 3-4 × 1-1.5 cm; veins fine, indistinct, longitudinal, more or less parallel. Cones globular to cylindric, 9-15 × 8-10.5 cm. Cone scales 340-440, with those from the equatorial section 3.4-4.1 × 3.9-4.6 cm. Pollen cones shortly pedunculate or almost sessile, usually axillary on slender leafy twigs, cylindric, 4-8.5(10) × 0.7-0.9 cm at maturity, bearing 600-1300 microsporophylls, each with 2-8 pollen sacs on the underside. Maturity July-September (Boland et al. 1985). Seeds narrowly cordate, winged. Wood creamy white to pale brown, similar to that of Agathis microstachya but with a density of 435-480 kg m-3. Sapwood and heartwood difficult to distinguish (Newbury [no date], Boland et al. 1985).
