Eucalyptus halophila, also known as salt lake mallee,[2] is a species of mallee or a shrub, that is endemic to Western Australia. It has smooth white and grey bark, sometimes rough and fibrous on the lower trunk, linear to narrow elliptic adult leaves, flower buds usually in grows of seven, white flowers and shortened spherical to barrel-shaped fruit.
Eucalyptus 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]
Eucalyptus 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]
Salt 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]
Eucalyptus halophila is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[6]
The 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]

Eucalyptus halophila (D.J.Carr & S.G.M.Carr, 1980) è un albero appartenente alla famiglia delle Myrtaceae, endemico del sud-est dell'Australia.[2][1]
Può raggiungere i 4 metri di altezza e il suo portamento è noto come mallee: ogni pianta produce diversi fusti che partono da un lignotubero.[1] Le foglie sono ellittico-lanceolate e misurano 5-8 cm (con un picciolo di meno di 1 cm) e la corteccia è marrone-grigiastra. Le infiorescenze sono ombrelle che portano fino a sette fiori bianchi.[3] Fiorisce tra febbraio e marzo.[3]
È una specie tipica delle coste dei laghi salati, diffusa principalmente nei dintorni di Esperance; il suo areale è comunque piuttosto frammentato.[1]
La lista rossa IUCN ha classificato questa specie come "vulnerabile" nel 2019 perché ha un areale ristretto e frammentato e perché le sue popolazioni, pur essendo stabili al momento della valutazione, hanno attraversato momenti di declino in passato da cui non si sono riprese.[1]
