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

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.[5]

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.[2][6] Ian Brooker disputes this interpretation and continues to use the name E. beyeri.[3]

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.[2][7]

Distribution and habitat

Beyer's ironbark grows in woodland in infertile soil from Narrabri to Nowra.[1]
