Eucalyptus petrensis, commonly known as limestone mallee, straggly mallee or koodjat,[1] is a mallee that is native to Western Australia.[2]

The mallee typically grows to a height of 1.5 to 4 metres (4.9 to 13.1 ft) and has a straggly habit with smooth bark. It blooms between June and October producing white flowers.

The bark has no glands and bisected cotyledons. The narrow evergreen leaves have a disjunct arrangement. The flowers have a calyx calyptrate that sheds early and the fruits that follow have a linear cuboid shape.[3] The mallee has a similar appearance to Eucalyptus foecunda but E. petrensis has a more persistent style on the fruit.[4]

The species was formally described by the botanists Ian Brooker and Stephen Hopper in 1993 as part of the work New series, subseries, species and subspecies of Eucalyptus (Myrtaceae) from Western Australia and from South Australia as publisher in the journal Nuytsia.[5] The type specimen was collected by Brooker in 1988 north west of Guilderton.[3]

The species is found on coastal limestone in an area along the west coast of Western Australia from the Wheatbelt extending through the Perth metropolitan area and Peel and South West regions from about Carnamah to Harvey where it grows in sandy soils.[2]
