Eucalyptus staeri


Eucalyptus staeri, commonly known as Albany blackbutt, is a species of small tree or a mallee and is endemic to the south-west corner of Western Australia. It has rough bark on the trunk and branches, thick, lance-shaped adult leaves, flowers buds in groups of between seven and fifteen, creamy white flowers and shortened spherical fruit.

Description

Eucalyptus staeri is a tree or a mallee that typically grows to a height of and forms a lignotuber. It has rough, fibrous, fissured, greyish brown bark on the trunk and branches thicker than about. Young plants and coppice regrowth have stems that are square in cross-section and leaves that are a lighter shade of green on the lower side, egg-shaped to broadly lance-shaped, long and wide. Adult leaves are the same shade of green on both sides, lance-shaped, long and wide on a petiole long. The flower buds are arranged in leaf s in groups of between seven and fifteen on a flattened, unbranched peduncle long, the individual buds on pedicels long. Mature buds are cylindrical to spindle-shaped, long and wide with a conical operculum. Flowering occurs from August or October to December or January or April and the flowers are creamy white. The fruit is a woody, shortened spherical capsule long and wide with the valves below rim level.

Taxonomy and naming

Albany blackbutt was first formally described in 1914 by Joseph Maiden in the Journal and Proceedings of the Royal Society of New South Wales and given the name Eucalyptus marginata var. staeri. In 1924 Stephen Lackey Kessell and Charles Gardner raised the variety to species status as Eucalyptus staeri. The specific epithet honours John Staer who collected the type specimens.

Distribution and habitat

Eucalyptus staeri is found mostly in the south west corner of the Great Southern region of Western Australia centred around the town of Albany with smaller populations extending north into the Wheatbelt. The preferred habitat is sandy soil in near-coastal scrubland.

Conservation status

This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
