Description

edit

Eucalyptus praetermissa is a mallet that typically grows to a height of 4–12 m (13–39 ft) but does not form a lignotuber. Young plants have egg-shaped leaves that are 40–70 mm (1.6–2.8 in) long and 15–30 mm (0.59–1.18 in) wide and petiolate. Adult leaves are arranged alternately, the same shade of dull green on both sides, lance-shaped, 50–100 mm (2.0–3.9 in) long and 10–20 mm (0.39–0.79 in) wide, tapering to a petiole 8–17 mm (0.31–0.67 in) long. The flower buds are arranged in leaf axils in groups of up to fifteen on an unbranched peduncle 10–18 mm (0.39–0.71 in) long, the individual buds on pedicels 2–4 mm (0.079–0.157 in) long. Mature buds are spindle-shaped, 11–15 mm (0.43–0.59 in) long and 2.5–4 mm (0.098–0.157 in) wide with an elongated, conical operculum about twice as long as the floral cup. Flowering occurs from November to January and the flowers are creamy white to pale yellow. The fruit is a woody, cylindrical to barrel-shaped capsule 6–8 mm (0.24–0.31 in) long and 4–6 mm (0.16–0.24 in) wide with the valves near rim level.[2][3][4]

Taxonomy and naming

edit

Eucalyptus praetermissa was first formally described in 1991 by Ian Brooker and Stephen Hopper from a specimen collected by Brooker on the north side of Beaufort Inlet in 1984.[4][5] The specific epithet (praetermissa) is a Latin word meaning "overlooked", "omitted" or "neglected", referring to the fact that this species was known but ignored.[6]

Distribution and habitat

edit

This eucalypt is only known from the type location where it grows in low woodland on sand over laterite.[2][4]

Conservation status

edit

This mallet is classified as "Priority Four" by the Government of Western Australia Department of Parks and Wildlife,[3] meaning that is rare or near threatened.[7]
