Pseudanthus

Pseudanthus is a genus of nine species of flowering plants in the family Picrodendraceae, and is endemic to Australia. Plants in the genus Pseudanthus are small, heath-like, monoecious shrubs with simple, leathery leaves, and flowers arranged in upper leaf axils, male flowers usually with three or six stamens and female flowers with three styles.

Description
Plants in the genus Micrantheum are heath-like, monoecious shrubs with simple, leathery leaves with thickened edges. The leaves are on a short petiole with tiny stipules at the base. The flowers are arranged in upper leaf axils with bracts at the base. Male flowers are arranged in clusters on a short peduncle, and have six stamens. Female flowers are arranged singly and have an ovary with two or three cells with two ovules per cell, and two or three styles. The fruit is a capsule containing seeds with a caruncle.

Taxonomy
The genus Pseudanthus was first formally described in 1827 by Kurt Polycarp Joachim Sprengel in Systema Vegetabilium, and the first species he described (the type species) was Pseudanthus pimeleoides.
