Eucalyptus beyeriana, commonly known as Beyer's ironbark, [3] is a small tree that is endemic to New South Wales. It has dark grey to black "ironbark", lance-shaped adult leaves, flower buds in groups of seven, white flowers and cup-shaped to conical or shortened spherical fruit. Its name is disputed with some authors considering it to be a synonym of Eucalyptus beyeri.

Description

Eucalyptus beyeriana is a tree, usually of low stature, that grows to a height of 20 to 25 metres (66 to 82 ft) and forms a lignotuber. It has rough, dark grey to black "ironbark" on its trunk and branches. The leaves on young plants and on coppice regrowth are lance-shaped, 55–90 mm (2–4 in) long, 10–15 mm (0.4–0.6 in) wide and have a petiole. Adult leaves are lance-shaped, 70–140 mm (3–6 in) long, 7–20 mm (0.3–0.8 in) wide on a petiole 8–20 mm (0.3–0.8 in) long and the same dull green on both sides. The flower buds are arranged in groups of seven on a peduncle 5–10 mm (0.2–0.4 in) long, the individual buds on a pedicel 2–7 mm (0.08–0.3 in) long. Mature buds are oval to diamond-shaped, 4–5 mm (0.16–0.20 in) long, 2–3 mm (0.08–0.1 in) wide with a conical to rounded operculum that is narrower than the floral cup. Flowering occurs between August and November and the flowers are white. The fruit is a woody cup-shaped, conical or flattened spherical capsule 3–6 mm (0.12–0.24 in) long and wide on a pedicel 3–7 mm (0.12–0.28 in) long. [3] [4] [5] [6]

Taxonomy and naming

Eucalyptus beyeriana was first formally described in 1990 by Lawrie Johnson and Ken Hill from a specimen collected near Wallacia. The description was published in the journal Telopea . [7]

Johnson and Hill considered that the species had been mistaken for E. beyeri, and that the type specimen of E. beyeri was a hybrid, with anthers intermediate between E. beyeriana and E. crebra , hence required a new name. Eucalyptus beyeri is now known as Eucalyptus × beyeri . [4] [8] Ian Brooker disputes this interpretation and continues to use the name E. beyeri. [5]

The specific epithets (beyeriana and beyeri) honour George Beyer, an herbarium assistant at the Sydney Technological Museum who assisted Richard Thomas Baker, the author of E. beyeri. [4] [9]

Distribution and habitat

Beyer's ironbark grows in woodland in infertile soil from Narrabri to Nowra. [3]
