Myoporum cordifolium | |
Myoporum cordifolium, commonly known as Jerramungup myoporum, is a plant in the figwort family, Scrophulariaceae. It is a shrub with thin, stiff branches and tiny, heart-shaped leaves, both covered with wart-like tubercles. Single white flowers with purple spots develop in the leaf axils and are followed by wrinkled green or brown fruits. It is endemic to a small area in the south-west of Western Australia
Myoporum cordifolium is an erect shrub which grows to a height of 1–1.5 metres (3–5 ft). It has wart-like tubercles covering its thin, stiff, twiggy branches and tiny, crowded, heart-shaped leaves. The leaves are fleshy, 1.3–3.8 millimetres (0.05–0.1 in) long and 1.2–3.7 millimetres (0.05–0.1 in) wide. [1] [2]
The flowers are solitary 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 2.0–3.5 millimetres (0.08–0.1 in) long and the lobes are spreading and 2.1–3.6 millimetres (0.08–0.1 in) long. There are 4 stamens which extend beyond the petals. Flowering occurs from June to November and is followed by wrinkled green or brown fruits which are drupes, 1–2.5 millimetres (0.04–0.1 in) long and slightly flattened. [1] [2]
Myoporum cordifolium was first formally described in 1859 by Ferdinand von Mueller in Fragmenta phytographiae Australiae and given the name Disoon cordifolius. [3] [4] In 1917, George Claridge Druce transferred it to the present genus. [5] The specific epithet (cordifolium) is derived from the Latin words cor, genitivecordis, "heart" and folium, "leaf", meaning "with heart-shaped leaves". [6]
Myoporum cordifolium occurs between the Ongerup and Jerramungup districts in the Esperance Plains, Jarrah Forest and Mallee biogeographic regions, [7] where it grows in sandy or clay loam. [8]
Myoporum cordifolium is classified as "Threatened" by the Western Australian Government Department of Parks and Wildlife [7] meaning that it is likely to become extinct or rare and therefore in need of special protection. [9] It has also been declared "vulnerable" by the Australian Government Department of the Environment. [10]

Eremophila delisseri is a flowering plant in the figwort family, Scrophulariaceae and is endemic to an area of the Nullarbor Plain in South Australia. it is a shrub with lilac-coloured flowers and with most of its parts covered with white hairs.
Eremophila eriocalyx, commonly known as desert pride, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is an erect shrub with greyish leaves, very hairy sepals and petals that range in colour from white to yellow, sometimes pink or purple.
Eremophila denticulata, also known as toothed eremophila, toothed poverty bush and Fitzgerald eremophila, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to the south-west of Western Australia. It is an erect shrub with red flowers and leaves that have toothed margins.
Eremophila clarkei, commonly known as turpentine bush, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia, South Australia and the Northern Territory. It is a shrub which is variable in form, but usually with narrow leaves and white or pale pink flowers. It is similar to Eremophila georgei and Eremophila granitica.
Eremophila fraseri, commonly known as burra or jilarnu, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is a shrub or small tree with all above-ground parts of the plant, apart from the petals, sticky and shiny due to the presence of a large amount of resin. The petals are coloured white, cream, pink and brown.
Verticordia verticordina is a flowering plant in the myrtle family, Myrtaceae and is endemic to a small area near the coast of the south-west of Western Australia. It is a small, low-growing shrub with crowded leaves and in spring, scattered pale greenish-cream and golden brown flowers. Its unusual flowers and fleshy leaves give the plant a superficial resemblance to a Darwinia.
Hakea commutata is a shrub in the family Proteaceae native to Western Australia. A variable species in shape and growing requirements, including mallee heath, sand and along creek lines.
Eremophila hughesii is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Australia. It is spindly, glabrous shrub with narrow leaves and with flowers that vary in colour from blue to pink, sometimes white. It is native to Western Australia and the Northern Territory.
Eremaea acutifolia, commonly known as rusty eremaea, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a small shrub with needle-like leaves and which bears orange-coloured flowers on short side branches and fruits with a surface that is rough to the touch.
Phymatocarpus maxwellii is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It resembles many small species of Melaleuca, mainly differing in the way its anthers are attached at the top of the stamens. In Phymatocarpus they are attached at their base and open at the other end through two slits. It is a shrub with many small heads of pink to purple flowers, often covering the plant for several weeks in October.
Myoporum caprarioides, commonly known as slender myoporum, is a plant in the figwort family, Scrophulariaceae. It is a shrub with wart-like tubercles covering its branches and leaves, especially on the upper surface and white flowers spotted with mauve, or all blue-mauve, present for most of the warmer months.
Myoporum oppositifolium, commonly known as twin-leaf myoporum, is a plant in the figwort family, Scrophulariaceae. It is easily distinguished from others in the genus by the combination of glabrous leaves and branches, its opposite leaf arrangement and its serrated leaves. Its distribution is restricted to the extreme south-west of Western Australia.
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.
Eremophila dempsteri is a flowering plant in the figwort family, Scrophulariaceae and is endemic to the south of Western Australia. It is an erect shrub with many upright stems, short, hooked leaves and pinkish-purple to white flowers with distinctive woolly sepals.
Eremophila exilifolia is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is a widely distributed shrub which is shaped like an inverted cone and has small, very sticky leaves and branches and lilac-coloured flowers.
Eremophila platycalyx is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is a shrub or small tree with its branches and leaves covered with a layer of matted hairs, although the hairs are sometimes obscured by resin. The shape of the leaves is variable, depending on subspecies, the sepals are often brightly coloured and the petals are cream-coloured, sometimes spotted on the outside. Two subspecies have been described but others have been discovered although not as yet formally described.
Eremophila psilocalyx is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is an erect shrub with a broom-like shape, narrow, hooked leaves and white, pink, blue or purple flowers. It is common in the mallee country around Esperance. It was sometimes incorrectly known as Eremophila pachyphylla.
Boronia gracilipes, commonly known as karri boronia, is a plant in the citrus family, Rutaceae and is endemic to the south-west of Western Australia. It is an erect, spindly shrub with compound leaves and pink, four-petalled flowers.
