Description

Eucalyptus behriana is a tree or a mallee that typically grows to a height of 12 metres (39 ft) and forms a lignotuber. It has rough, fibrous, dark brown to black bark on the base of the trunk and smooth greyish, greenish or coppery bark on the upper trunk and branches. Leaves on young plants and on coppice regrowth are arranged alternately, egg-shaped, 50–105 mm (2–4 in) long, 25–65 mm (1–3 in) wide and have a petiole. The adult leaves are arranged alternately, broadly lance-shaped to egg-shaped, 45–130 mm (2–5 in) long, 13–50 mm (0.5–2 in) wide on a petiole 10–22 mm (0.4–0.9 in) long, and the same glossy green on both sides.[3][4][5][6][7]

The flower buds are arranged in groups of seven, mostly on the ends of the branches on a peduncle 3–10 mm (0.1–0.4 in) long, the individual flowers usually sessile. Mature buds are oblong to oval, green to brownish, 3–7 mm (0.1–0.3 in) long and 2–4 mm (0.08–0.2 in) wide with a conical to rounded operculum. Flowering mainly occurs from September to February and the flowers are white. The fruit that follows is a woody, cup-shaped or barrel-shaped capsule 3 to 6 mm (0.12 to 0.24 in) long and 3 to 5 mm (0.12 to 0.20 in) in diameter.[3][4][5][6][7]

Taxonomy and naming

Eucalyptus behriana was first formally described by Victorian Government Botanist Ferdinand von Mueller in 1855 and the description was published in Transactions and Proceedings of the Victorian Institute for the Advancement of Science.[8][9] The specific epithet (behriana) honours Hans Hermann Behr.[4]

Distribution

Eucalyptus behriana has a disjunct distribution in south-eastern Australia. In New South Wales it occurs in mallee shrubland near West Wyalong. In Victoria it occurs in the Mallee and Wimmera in the north-west, with the exception of a small outlying population in the south near Bacchus Marsh including Long Forest Nature Conservation Reserve.[3] In South Australia, it has a scattered distribution across the south-east.[10]
