Description

Myoporum crassifolium is a shrub or small tree which grows to a height of 6 metres (20 ft). The leaves are arranged alternately and are 28–145 millimetres (1–6 in) long, 11–44 millimetres (0.4–2 in) wide, glabrous, thick and fleshy. They are elliptic to egg-shaped, sometimes with the narrower end towards the base, shiny on both surfaces with the mid-vein more prominent on the lower surface. [1]

The flowers are arranged in groups of 3 to 6 in the axils of the leaves and have 5 sepals and 5 white, spotted pink petals joined at their base to form a tube. The tube is 4–6 millimetres (0.16–0.24 in) long and the lobes are spreading and 2.2–3.6 millimetres (0.09–0.1 in) long. There are 4 stamens which extend slightly beyond the petals. The fruit is a pale purple to mauve, roughly spherical drupe, 5–7 millimetres (0.2–0.3 in) long. [1]

Taxonomy and naming

Myoporum crassifolium was first formally described in 1786 by Georg Forster in Florulae Insularum Australium Prodromus . [2] [3] The specific epithet (crassifolium) means "thick-leaved". [1]

Distribution and habitat

Myoporum crassifolium occurs in New Caledonia including the Loyalty Islands [4] and on Efate and Aneityum islands in Vanuatu. It grows in shrubland and on rocky areas behind beaches. [1]

Conservation

Myoporum crassifolium is classified as "not threatened". [1]

Uses

Essential oils

On the L'Île-des-Pins, this species is an ingredient of a medicinal preparation and inner parts of the branches can be used as torches, burning with a white light and producing a pleasant scent. [5] More than 80% of the essential oil extracted from Myoporum crassifolium is bisabolol. [6]
