Myoporum stokesii

Myoporum stokesii is a plant in the figwort family, Scrophulariaceae and is endemic to the island of Raivavae in French Polynesia. It is similar to the two other members of its genus on the island, Myoporum rapense and Myoporum rimatarense although the former has serrated leaves and the latter has wider leaves and differently shaped fruits.

Description

Myoporum stokesii is a shrub or small tree sometimes growing to a height of 5 metres (20 ft) with young branches that are flattened or three-sided. The older branches are wrinkled and have raised leaf bases. The leaves are arranged alternately and are mostly 45–80 millimetres (2–3 in) long, 9–17 millimetres (0.4–0.7 in) wide, the same colour on both surfaces and have a distinct mid-vein on the lower surface. [3]

The flowers are borne singly or in pairs in the axils of leaves on a stalk 7–15 millimetres (0.3–0.6 in) long and have 5 pointed sepals and 5 petals forming a tube or bell-shape. The tube is 5–6 millimetres (0.20–0.24 in) long with lobes about the same length or slightly shorter. The tube is white, sometimes spotted and is hairy inside and on the inner parts of the lobes. There are four stamens which extend beyond the petal tube. The fruits is a three or four-sided, cone-shaped drupe. [3]

Taxonomy

Myoporum stokesii 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 stokesii honours the collector of the type specimen, A.M. Stokes. [3]

Distribution and habitat

Myoporum stokesii is only found on Raivavae where it grows on rocky hillsides. [3]

Conservation

Myoporum stokesii is listed as "critically endangered" in the IUCN Red List. [1]

Its flowers have five white petals and are arranged in small groups in the leaf axils. The fruits which follow are more or less spherical, soft, cream coloured drupes. As its common name suggests, this plant is restricted to higher places, around 1,000 metres (3,000 ft) above sea level. It occurs in the McPherson Range and nearby mountains of New South Wales and Queensland.

It has similar flowers and fruits and grows in similar environments to Myoporum tetrandrum but differs from it and all other members of the genus by having hairs on the outer edge of the petals.

<i>Myoporum wilderi</i> Species of flowering plant

Myoporum wilderi, commonly known as Cook Islands myoporum or ngaio, is a plant in the figwort family, Scrophulariaceae and is endemic to the islands of Mangaia and Mitiaro in the Cook Islands.

Glycocystis beckeri is the only species of the flowering plant genus Glycocystis in the family Scrophulariaceae and is endemic to the south west of Western Australia. It is a shrub, similar to others in the genera Eremophila and Myoporum but is unusual in that it produces very large amounts of sticky, sweet-smelling resin produced by raised glands which cover the entire plant, except for the petals. It has been suggested that the resin traps insects which the plant uses as a source of nitrogen.
