Eucalyptus newbeyi, commonly known as Beaufort Inlet mallee,[2] is a species of mallee that is endemic to a small area on the south coast of Western Australia. It has smooth, mottled bark, narrow leaves, flower buds usually in groups of seven, yellowish green flowers and bell-shaped to conical fruit.

Description[]

Eucalyptus newbeyi is a mallee that typically grows to a height of 5–8 m (16–26 ft) and does not form a lignotuber. It has smooth, mottled yellowish brown bark that is shed in flakes. The adult leaves are narrow lance-shaped to narrow elliptical, 40–80 mm (1.6–3.1 in) long and 5–15 mm (0.20–0.59 in) wide tapering to a petiole 5–10 mm (0.20–0.39 in) long. The flower buds are arranged in leaf axils in groups of seven, rarely three or nine, on a downturned, strap-like peduncle 30–55 mm (1.2–2.2 in) long, the individual buds sessile. Mature buds are 52–60 mm (2.0–2.4 in) long and 11–16 mm (0.43–0.63 in) wide, with the horn-shaped operculum three or four times as long as the floral cup. Flowering occurs between September and February and the flowers are yellowish green. The fruit is a woody, bell-shaped to conical capsule, 10–27 mm (0.39–1.06 in) long and 18–28 mm (0.71–1.10 in) wide.[2][3][4]

Eucalyptus newbeyi can be distinguished from the closely related Burdett gum (E. burdettiana) by its smooth, horn-shaped rather than warty operculum. It can also be distinguished from the warted yate (E. megacornuta) which has grossly warted bud caps and fruit that are bell shaped.[5]

Taxonomy and naming[]

Eucalyptus newbeyi was first formally described in 1980 by and Stella Carr in the Australian Journal of Botany, from specimens collected by Alex George near the Fitzgerald River in 1970.[6] The specific epithet (newbeyi) honours Ken Newbeyi (1936-1988), a botanical collecter and ecologist from Ongerup.[3]

Distribution and habitat[]

The Beaufort Inlet mallee is found on steep slopes and on riverbank cliffs in shrubland near Beaufort Inlet and in the Fitzgerald River National Park, growing in sandy-clay-loam soils.[2][3][4]

Conservation status[]

This eucalypt is classified as "Priority Three" by the Western Australian Government Department of Parks and Wildlife,[2] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[7]
