Eucalyptus conglobata, also known as the cong mallee or Port Lincoln mallee,[3] is a species of eucalypt that is native to the south coast of Western Australia and South Australia. It is a mallee with smooth bark, lance-shaped adult leaves, flower buds in groups of seven, white flowers and clustered hemispherical fruit.

Description

Eucalyptus conglomerata is a mallee that typically grows to a height of 5–8 m (16–26 ft) or rarely a tree to 20 m (66 ft). It has smooth grey to brown-tan over creamy grey bark. Its young plants and

capsules crowded together and flattened on one side.[3][4][5][6][7]

Taxonomy and naming

Cong mallee was first formally described in 1867 by George Bentham from an unpublished description by Robert Brown who gave it the name Eucalyptus dumosa var. conglobata.[8] The description was published in Flora Australiensis.[9] In 1922, Joseph Maiden raised the variety to species status as Eucalyptus conglobata.[10][11]

In 1972 Ian Brooker described two subspecies, subsp. conglobata as a synonym of Eucalyptus dumosa var. conglobata, and subsp. fraseri.[12] Eucalyptus conglobata (R.Br. ex Benth.) Maiden subsp. conglobata is accepted by the Australian Plant Census.[13]

In 2004, Brooker and Andrew Slee described Eucalyptus conglobata subsp. perata, a name that has been accepted by the Australian Plant Census.[14][15]

The specific epithet (conglobata) possibly refers to the clusters of flower buds and fruit.[3] The name perata is from the Latin peratus meaning "western", referring to the distribution of this subspecies compared to subspecies conglobata.[14]

Subspecies conglobata has fruit that are 7–11 mm (0.28–0.43 in) in diameter whereas subspecies perata has narrower leaves, smaller buds and fruit 5–7 mm (0.20–0.28 in) in diameter.[3]

Distribution and habitat

Cong mallee grows in tall shrubland. Subspecies conglobata is the only subspecies occurring in South Australia where it occurs near

Stirling Ranges, Fitzgerald River National Park and Ravensthorpe. Where the ranges overlap, it is difficult to distinguish between the two subspecies.[3][17]

Conservation status

Both subspecies of Eucalyptus conglobata are classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[16][17]
