Lophostemon suaveolens

Lophostemon suaveolens, the swamp turpentine or swamp box, is an evergreen tree in the Myrtaceae usually 8–20 m tall but occasionally reaching 30 m, with a straight trunk and an open, somewhat irregular crown. The bark is persistent on the trunk and main branches, fibrous, soft, and dark grey-brown, but the smaller branches shed in long ribbons exposing smooth, creamy underbark. Young growth is densely silvery-pubescent. Leaves are clustered toward branch tips in pseudo-whorls of three to five, simple, elliptic to obovate-lanceolate, 7–15 cm long and 2–4 cm wide, dull grey-green above and paler and softly hairy beneath, with entire margins and a prominent midrib. Inflorescences are axillary cymes of 3–7 fragrant flowers; each flower is 1.5–2 cm across with five whitish, deeply fringed petals and numerous stamens fused into five conspicuous bundles. The fruit is a woody, top-shaped capsule 5–8 mm across that opens by three valves. It grows in seasonally swampy woodlands and stream margins across tropical northern Australia and New Guinea.
