Eucalyptus cupularis, commonly known as the Halls Creek ghost gum,[1] Halls Creek white gum, is a eucalypt that is native to Western Australia[2] and the Northern Territory.[3] It is known by the indigenous Jaru peoples as wawulinggi.[4]
The tree typically grows to a height of 5 to 9 metres (16 to 30 ft) and as high as 12 metres (39 ft). It has powdery white smooth bark.[2] Adult leaves are disjunct, dull, green, thin and concolorous. The leaf blade has a narrow lanceolate to broad lanceolate shape that is basally tapered.[3]
The tree blooms between October and November[2] producing a simple axillary conflorescence with seven flowered umbellasters on quadrangular peduncles. Buds are ovoid or pyriform or conical with a calyptrate calyx that shed early with cream to white flowers. Fruits that form later are cylindrical or conical with a flat disc.[3]
The species was first formally identified by the botanist Charles Austin Gardner in 1964 as part of the work Contributiones Florae Australiae Occidentalis published in the Journal of the Royal Society of Western Australia.[5]
E. cupularis is similar in appearance to and closely related to the Kalumburu Gum (Eucalyptus herbertiana) and the Mountain White Gum (Eucalyptus mooreana).[6]
The range of the plant extends from the Kimberley region of Western Australia and extends into the Northern Territory where it grows on stony hills and along watercourses in skeletal soils over sandstone or granite.[2]
