Description

Myoporum rimatarense is a small tree growing to a height of 6 metres (20 ft). The leaves are arranged alternately and are 66–80 millimetres (2.6–3.1 in) long, 22–35 millimetres (0.9–1 in) wide, the same colour on both surfaces and with a mid-vein visible on the lower surface.[3]

The flowers are borne singly or in groups of up to 4 in the axils of leaves on stalks 6–8.5 millimetres (0.2–0.3 in) long and have 5 pointed sepals. The size, shape and colour of the petals and stamens is not known. The fruit is a more or less spherical drupe.[3]

Taxonomy

Myoporum rimatarense was first formally described in 1935 by Forest B. H. Brown and the description was published in Bernice P. Bishop Museum Bulletin.[2] The specific epithet rimatarense refers to the name of the island where the type specimen was collected by A.M.Stokes.[3]

Distribution and habitat

Myoporum rimatarense was only found on Rimatara Island. The type specimen was collected on a sandy beach near the village of Amaru.[3]

Conservation

An extensive search in 2004 failed to find a single specimen and the species is now presumed extinct.[3][4][5]
