Notes
Tree to 50 m high. Bark smooth, shedding in long ribbons. The bases of the trunks of older trees usually have slabs of rough bark shedding in large strips and slabs. Juvenile stems square in cross section and prominently winged, glaucous. Branchlets occasionally glaucous. Juvenile leaves stem-clasping and opposite each other for many pairs, 3–11.5 cm long, 17–60 mm wide, upper surface green or slightly glaucous, lower surface conspicuously white-waxy. Adult leaves alternating up the stems, 12–40 cm long, 12–60 mm wide, glossy to dull, green. Flowers white, with 0 petals. Mature flower buds glaucous, sometimes green to yellow, caps warty with a central conical projection, 8–18 mm long, caps as long as or shorter than the base. Flowers summer-winter. Gumnuts 6–22 mm in diameter. Gumnuts that have dropped their seed have protruding valves or valves that are not very noticeable.
subsp. bicostata: flower buds and gumnuts in 3s. Flower clusters with stalks 0–4 mm long. Individual flower buds stalkless (rarely the central bud with stalk to 2 mm long). Gumnuts 2-ribbed longitudinally, glaucous or non-glaucous.
