Balaustion is a genus of flowering plants in the myrtle family, Myrtaceae and is endemic to Western Australia.
Plants in the genus Balaustion are glabrous, prostrate to erect shrubs with flowering branchlets with up to six pairs of flowers. The leaves are arranged in opposite pairs and decussate, linear to more or less circular with oil glands on the lower surface. The flower clusters are borne on a peduncle, each flower sessile or on a long pedicel. There are five sepals that are shorter than the petals and five egg-shaped to broadly elliptic petals with 13 to 35 stamens. The fruit is a slightly kidney-shaped capsule with a rounded outer surface with two equal lateral surfaces and a large inner surface 1.2–2.6 mm (0.047–0.102 in) long. [2] [3] [4]
The genus Balaustion was first described by William Jackson Hooker in his Icones Plantarum , and the first species he described (the type species) was Balaustion pulcherrimum . [5] [6]
