Pseudanthus orientalis is a compact, rigid, glabrous monoecious shrub that typically grows to a height of with low lying stems up to long. Its leaves are linear to narrowly oblong, long and wide on a petiole long with pale reddish-brown, broadly triangular stipules long at the base. The flowers are arranged singly in leaf axils, but often appear clustered on the ends of branches with narrowly triangular bracts long at the base. Male flowers are on a pedicel long, the 6 tepals usually narrowly oblong and pale yellow to creamy-white, long and wide and there are usually 6 stamens. Female flowers are sessile, the 6 tepals pale green with reddish tips, long and wide. Flowering has been observed in most months with a peak from August to November, and the fruit is a narrowly oval, glossy brown capsule long.[1] [2]
Pseudanthus orientalis was first formally described in 1860 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae.[3] [4] The specific epithet (orientalis) means "pertaining to the east".[5]
This species of shrub grows on coastal dunes and coastal heath from Shoalwater Bay on the coast of Queensland to Botany Bay in New South Wales.[1] [2]
