Eremophila mackinlayi is a species of flowering plant in the family Scrophulariaceae, commonly referred to as an eremophila or “emu bush.” It is endemic to arid and semi‑arid regions of Western Australia.
Taxonomy
- Kingdom: Plantae
- Clade: Tracheophytes
- Clade: Angiosperms
- Clade: Eudicots
- Order: Lamiales
- Family: Scrophulariaceae
- Genus: Eremophila
- Species: E. mackinlayi
The species was formally described by the botanist Ferdinand von Mueller. The specific epithet mackinlayi honors the 19th‑century explorer and surveyor William Mackinlay, who contributed to the exploration of Western Australia.
Description
Eremophila mackinlayi is an evergreen shrub typically ranging from 0.3 to 2 m in height. The plant bears linear to lanceolate leaves that are usually glabrous (smooth) and may display a greyish or green coloration. Flowers are borne singly in leaf axils, featuring a tubular corolla that is commonly pink, mauve, or purple, although variants in coloration have been reported. The corolla tube is enclosed by five lobes, and the plant produces a dry, woody fruit typical of the genus.
Distribution and Habitat
The species is confined to the Gascoyne, Pilbara, and Mid West regions of Western Australia. It occurs on stony or sandy soils, often in open shrubland or mulga woodlands, and is adapted to the region’s low rainfall and high temperature conditions.
Ecology
Like other eremophilas, E. mackinlayi is pollinated primarily by insects, particularly native bees, and possibly by birds in some locales. The plant’s drought tolerance and ability to thrive in poor soils make it a component of the arid‑zone vegetation community.
Conservation Status
According to the Department of Biodiversity, Conservation and Attractions (Western Australia), Eremophila mackinlayi is currently listed as “Not Threatened,” indicating a stable population within its native range. Ongoing monitoring is conducted to assess potential impacts from land use change and climate variability.
Cultivation and Uses
The species is occasionally cultivated in Australian native gardens for its attractive flowers and resilience to drought. It may be propagated from cuttings or seeds, with a preference for well‑drained, low‑fertility soils. No significant commercial or medicinal uses have been documented in the literature.
