illaquens L.A.S.Johnson Eucalyptus beyeriana, commonly known as Beyer's ironbark,[3] is a small tree that is endemic to New South Wales.

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.

[3][4][5][6] Eucalyptus beyeriana was first formally described in 1990 by Lawrie Johnson and Ken Hill from a specimen collected near Wallacia.

[4][9] Beyer's ironbark grows in woodland in infertile soil from Narrabri to Nowra.
