Definition
Eremophila glabra is a species of flowering plant in the family Scrophulariaceae, endemic to arid and semi‑arid regions of mainland Australia. It is commonly known as the "emu bush" or "native fuchsia."
Overview
The species is a hardy, evergreen shrub that occurs across a wide distribution, including Western Australia, the Northern Territory, South Australia, Queensland, and New South Wales. It typically inhabits sandy or rocky soils on flats, dunes, and low hills, often within mulga or spinifex communities. E. glabra is cultivated in horticulture for its attractive foliage and profuse tubular flowers, which attract nectar‑feeding birds and insects.
Etymology / Origin
The generic name Eremophila derives from the Greek words eremos (“desert”) and philos (“loving”), reflecting the plant’s adaptation to dry habitats. The specific epithet glabra is Latin for “smooth” or “hairless,” referring to the relatively glabrous (non‑hairy) surfaces of the leaves and stems in comparison with other species in the genus.
Characteristics
- Growth form: An erect to spreading shrub, typically 0.3–3 m tall, with many slender, often arching branches.
- Leaves: Linear to lanceolate, 10–40 mm long, 1–3 mm wide, usually sessile, and mostly glabrous; the leaf margins may be slightly revolute.
- Flowers: Solitary or in small clusters in leaf axils; corolla tubular, 15–30 mm long, exhibiting colors ranging from pale mauve and purple to white or pink. The external surface of the corolla tube may be covered with fine hairs, while the inside is smooth.
- Fruit: A dry, ribbed capsule about 5–8 mm long, containing numerous tiny seeds that are dispersed by wind.
- Phenology: Flowering occurs mainly in spring and summer but may be opportunistic following rainfall events.
- Ecology: The nectar-rich flowers are visited by honeyeaters, particularly the emu‑bush’s namesake insect‑pollinated birds, and by various native bees. The plant is drought‑tolerant and can resprout after fire, contributing to post‑fire regeneration in its native ecosystems.
