Eremophila denticulata, also known as toothed eremophila, toothed poverty bush and Fitzgerald eremophila, [2] 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 denticulata is an erect shrub growing to 1–2.5 m (3–8 ft) tall with shiny, sticky branches and leaves due to the presence of resin. The leaves are arranged alternately and are mostly 34–60 mm (1–2 in) long, 6–16 mm (0.2–0.6 in) wide, elliptic to lance-shaped, deep green in colour and have edges that are usually toothed. Young leaves are often very sticky. [3] [4] [5] [6] [7]
The flowers are borne singly in leaf axils on a stalk 15–30 mm (0.6–1 in) long. There are 5 lance-shaped, pointed, greenish-coloured sepals which are 3.5–13 mm (0.1–0.5 in) long and slightly sticky. The petals are 25–30 mm (0.98–1.2 in) long and joined at their lower end to form a tube. The flower buds are orange-coloured but the open flower is bright red, rarely yellow. The petal tube is usually mostly covered with glandular hairs but the inside of the tube and the lower lobe have longer, softer hairs. The 4 stamens extend beyond the end of the petal tube. Flowering occurs from August to February and is followed by fruits which are dry, oval shaped with a pointed end, have a papery covering and are 10–15 mm (0.4–0.6 in) long. [3] [4]
The species was first formally described in 1859 by Ferdinand von Mueller in Fragmenta phytographiae Australiae . [8] [9]
In 2007, Robert Chinnock described two subspecies of E. denticulata and the names have been accepted by the Australian Plant Census:
The specific epithet is derived from the "Latin denticulata, finely dentate, very small teeth." The epithet trisulcata is derived from the "Latin trisulcata, three-furrowed". [3]
Eremophila denticulata subsp. denticulata occurs near Ravensthorpe. [3] [4] [12] There is a record by "Black" in South Australia but this report has not been accepted. [13] Eremophila denticulata subsp. trisulcata occurs near Mount Buraminya and Mount Ragged in the Cape Arid National Park. [3] [4] [6] [14]
Eremophila denticulata is pollinated by birds. Subspecies trisulcata becomes rare in its range when not disturbed. After fire, the number of individual plants increases dramatically. [6]
Both subspecies of Eremophila densifolia are classified as "Threatened Flora (Declared Rare Flora — Extant)" by the Department of Environment and Conservation (Western Australia). [15] An Interim Recovery Plan has been prepared for subspecies trisulcata. [16]
Toothed poverty bush is well known in cultivation. It is suitable for larger gardens, especially where fast growth is required but is inclined to break branches in windy locations. It is difficult to propagate from seed but easily grown from cuttings. In high rainfall areas it is preferable to graft onto Myoporum species. It will grow well in most soils and is both drought and frost tolerant. [5] [7]
Eremophila youngii is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is a dense, erect shrub with many of its parts covered with a layer of grey to yellowish-grey scales and with pink, purple or red flowers.
Eremophila oldfieldii, commonly known as pixie bush, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is a shrub or small tree with rough bark, broad, flat or narrow fleshy leaves and red, orange or yellow flowers.
Eremophila bowmanii, also known as silver turkeybush, Bowman's poverty bush and flannel bush, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to New South Wales and Queensland in Australia. It is a low to medium, spreading shrub with silvery-grey, hairy foliage and blue to lilac flowers, and sometimes grows in dense thickets with mulga.
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.
Eremophila mackinlayi, commonly known as desert pride, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is a shrub with its branches and leaves covered with a thick layer of yellow to grey hairs, mostly egg-shaped leaves and deep lilac-coloured to purple flowers. It is most closely related to E. strongylophylla and E. hygrophana and sometimes occurs in the same areas as these species.
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 endemic to Western Australia and the Northern Territory.
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 caerulea, commonly known as spotted eremophila, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to the south-west of Western Australia. It is a low, compact, spreading shrub with narrow, warty, cylindrical leaves and blue to purple flowers.

It is a variable shrub, usually with sticky branches and leaves, long, thin leaves and mauve or purple flowers in spring.
Eremophila elderi, commonly known as aromatic emu bush, is a flowering plant in the figwort family, Scrophulariaceae. It is endemic to central Australia where it grows near the border between Western Australia, South Australia and the Northern Territory. It is an erect, aromatic shrub with sticky leaves and branches and usually pale coloured to white flowers. Its specific epithet (elderi) honours an early Australian businessman, Thomas Elder.

Six subspecies are recognised by the Western Australian Government Department of Parks and Wildlife.
