Description
editEucalyptus halophila is a shrub or mallee that typically grows to a height of 1 to 4 metres (3 to 13 ft), sometime to 7 m (23 ft), or a shrub up to 2 m (6 ft 7 in) tall, and forms a lignotuber. It has smooth white and pale grey bark, sometimes with fibrous bark on the lower half of its stems. Young plants and coppice regrowth have leaves that are linear, 40–85 mm (1.6–3.3 in) long and 3–6 mm (0.12–0.24 in) wide. Adult leaves are linear to narrow elliptic, the same dull green colour on both sides, 50–80 mm (2.0–3.1 in) long and 5–12 mm (0.20–0.47 in) wide on a petiole 3–9 mm (0.12–0.35 in) long. The flower buds are arranged in leaf axils in groups of seven, sometimes three, on an unbranched peduncle 5–13 mm (0.20–0.51 in) long, the individual buds on pedicels 2–3 mm (0.079–0.118 in) long. Mature buds are pear-shaped, 4–5 mm (0.16–0.20 in) long and 3–5 mm (0.12–0.20 in) wide with a conical to rounded operculum. Flowering occurs from January to May and the flowers are creamy white. The fruit is a woody, shortened spherical or barrel-shaped fruit that is 5–9 mm (0.20–0.35 in) long and 5–8 mm (0.20–0.31 in) wide with the valves enclosed below rim level.[3][4][5][6][7]
Taxonomy and naming
editEucalyptus halophila was first formally described in 1980 by Denis and Maisie Carr from a specimen Maisie collected with Alex George near a small salt pan near Dalyup. The description was published in the journal Nuytsia.[8] The specific epithet (halophila) is derived from ancient Greek word meaning "salt" with the ending -philus meaning "loving", referring to the habitat of this species.[9][10][11]
Distribution and habitat
editSalt lake mallee grows in sandy clay soils on flat areas in shrubland adjacent to salt lakes. It is only known from the catchment of the Dalyup River between Dalyup and Mount Ney near Esperance in the Esperance Plains and Mallee biogeographic regions.[6]
Conservation status
editEucalyptus halophila is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[6]
Use in horticulture
editThe plant is available commercially in seed form or as tubestock and is grown as an ornamental or low shelter plant. It is tolerant of frost, salt and drought and has a moderately fast growth rate.[2]
