Peripentadenia mearsii

Peripentadenia mearsii, commonly known as the buff quandong or grey quandong, is a plant in the family Elaeocarpaceae endemic to a small part of northeastern Queensland, Australia. It is usually seen as a multistemmed tree, and the habitat is tropical rainforest.

Description
Peripentadenia mearsii is a tree up to 20 m tall. The leaves are dark green above and paler below with toothed margins. They measure up to 14 cm long by 5 cm wide and are held on a petiole about 2 cm long. The white flowers have 5 petals about 22 mm long by 13 mm wide, each with several lobes at their apices. The fruits are or ovoid capsules about 30 mm long by 20 mm wide, containing a single brown seed enclosed in a red aril.

Taxonomy
This species was first described (as Actephila mearsii) by the Australian botanist Cyril Tenison White in 1938, and published in 1939. White's description was based on samples of fruit and leaves only, and he placed the species in the family Euphorbiaceae. However in 1957 another Australian botanist – Lindsay Stuart Smith – erected the new genus Peripentadenia within the family Elaeocarpaceae to accommodate this plant. At the time, it was the only species in the genus.
