Adult leaves are lance-shaped to curved, the same glossy green on both sides, Шаблон:Convert long and Шаблон:Convert wide on a petiole Шаблон:Convert long. The flower buds are borne in groups of seven or nine in leaf axils on an unbranched peduncle Шаблон:Convert long, the individual buds on a pedicel Шаблон:Convert long. Mature buds are oval to cylindrical, Шаблон:Convert long and Шаблон:Convert wide with a conical operculum Шаблон:Convert long. Flowering mainly occurs in March and April and the flowers are creamy white. The fruit is a woody cup-shaped or conical capsule Шаблон:Convert long and Шаблон:Convert wide on a pedicel Шаблон:Convert long, the valves just above of slightly below the rim.[2][3][4][5][6][7]

Taxonomy and naming

Eucalyptus calcareana was first formally described in 1979 by Clifford Boomsma from specimens collected near Nundroo.[5][8] The specific epithet (calcareana) is derived from the Latin word calcareus meaning "of lime" or "limy"[9] referring to the soil type where this species grows.[3]

Distribution and habitat

Nundroo mallee is found along the south coast of the Goldfields-Esperance region of Western Australia and the south coast of South Australia.[7] It is found from the east of Esperance to coastal areas of the western Eyre Peninsula.[7][10]

Use in horticulture

This eucalypt is grown in exposed locations and is suitable as a windbreak or shade tree.[10]
