Triplarina

Plants in the genus Triplarina are shrubs with small leaves arranged in opposite pairs, sometimes with wavy or finely-toothed edges, and oil-dots visible on the lower surface. The flowers are arranged in leaf axils, sometimes in pairs and the flowers have five sepals, five petals and fourteen to eighteen stamens. The sepals remain attached to the fruit but the petals that are white to deep pink and more or less round are lost as the fruit develops. The ovary is half-inferior and has three locules, each containing eight to thirteen ovules, and the fruit is a capsule containing kidney-shaped seeds.[2][3]

The genus Triplarina was first formally described in 1838 by Constantine Samuel Rafinesque in his book Sylva Telluriana.[4][5] The first species he described was T. camphorata, now known as Triplarina imbricata.[3][5][6]

Shrubs in the genus Triplarina usually grow in woodland or forest, rarely in heath, and are mostly found in small, isolated populations in sheltered positions near the coast, although T. paludosa grows on tablelands 180 km (110 mi) from the coast. They occur from near Ravenshoe in Queensland to near Nowra in New South Wales.
