Peduncles flat, strap-like. Individual flowers pedicellate. Operculum cornute to conical, about 5-6 mm diam., longer than the calyx tube (hypanthium). Outer operculum shed early, before the mature bud stage.
Cotyledons reniform or +/- bilobed. Oil dots more obvious near the margins but visible only with a lens. At the tenth leaf stage: leaf blade narrowly elliptic or lanceolate, glabrous, scattered oil dots visible with a lens. Lignotuber absent.
Distribution and Ecology
This species produces a useful timber and is well suited for use in polished floors. Swain (1928).
Trees of this species sometimes have 'wells' located in the bark of the upper stem. These 'wells' are the work of the Yellow-Bellied Gliders which chew the holes and then return each night to feed on the exudate from the damaged phloem or cambial layer.
