Agathis orbicula De Laub.

Tree to 40 m tall. A light yellow resin is produced in some abundance. Juvenile leaves ovate and bluntly acute, to 6.5 cm by 28 mm. Adult leaves ovate to orbicular, broadly rounded to slightly angled at the apex, 24-40 by 12-24 mm, tapering sharply at the base to a 3-7 mm petiole, glaucous on the underside. Mature pollen cones 8-14 by 4-6 mm, subtended by a 2-6 mm peduncle, the apex of the microsporophyll helmet-shaped, 1.2-1.5 by 1 — 1.2 mm, apex blunt. Seed cone oval, c. 7 by 4.5 cm. Seed bract with an acute ridge along the apical margin, ovate with a 4 mm scallop spreading nearly perpendicularly to each side of the base, c. 20 mm high and 33 mm broad. Seed unknown but leaving a blunt impression suggesting a shape like that of A. lenticula.

Scattered in rain-forests and kerangas on low mountains and plateaus between 450 and 1050 m.
