Taxonomy

First collected near Roma in central Queensland, the stringybark she-oak was described by Ferdinand von Mueller and Frederick Manson Bailey in 1882 as Casuarina inophloia.[2] Exactly 100 years later, Lawrie Johnson moved it to its current genus Allocasuarina in his revision of the she-oaks.[3]

Description

Allocasuarina inophloia grows as a small tree with an open habit ranging from 3 to 10 metres (10 to 33 ft) high. It is dioecious.[4] Like all she-oaks, its foliage is composed of segmented branchlets with segments known as articles, its leaves reduced to tiny scales between them.[5]

Distribution and habitat

In New South Wales it occurs in areas such as the Clarence River valley, Emmaville, Yetman,[4] south to Waralda, while it ranges in Queensland north to Herberton.[6] It is found in woodland on sandstone, ironstone or laterite ridges.[4][6] Associated species include grasstrees (Xanthorrhoea) and eucalypts, such as drooping ironbark (Eucalyptus caleyi).[7]

Northwest of Glen Innes it is found in tall scrub on granitic soil uplands with other dominant species such as the she-oak species Allocasuarina brachystachya, wattle species Acacia williamsiana and the endangered Severn River heath-myrtle (Micromyrtus grandis) and understory shrubs such as Leucopogon neo-anglicus and fringe myrtle (Calytrix tetragona).[7]

It has been recorded as a host plant for the orange mistletoe (Dendrophthoe glabrescens).[8]

Cultivation

Its shaggy bark gives the species its horticultural potential. It is frost hardy and able to tolerate poor soils.[5]
