Allocasuarina inophloia: is a member of the Casuarinaceae family and is known as the Stringybark She Oak. This species was previously known as Casuarina inophloia.
Allocasuarina inophloia is a spreading tree that may reach a height of ten metres. The distinctive bark is fibrous and breaks off in long strips (hence the common name). The species name means thread-like bark. As with all members of the family the leaves are reduced to whorls of teeth around the slender branches. The branches are continually shed and form mulch around the plants.
Allocasuarina inophloia is dioecious (male and female flowers are carried on different plants). The male flowers are small and appear in cylindrical spikes on the ends of branches. As they mature the ends of the branches become brown and pollen is shed and carried by the wind. Female flowers appear along branches in egg-shaped or globular clusters. They are carried on short stalks. Female flowers (if pollinated) develop into cones about two centimetres long. These contain a number of black samaras (dry fruits with walls expanded into wings). The winged structure aids in fruit dispersal when the cones open. Usually the cones are persistent.
Allocasuarina inophloia has distinctive bark that is unique in the genus and is a very decorative feature. The wood is red and close-grained.
The Stringybark She Oak is an attractive tree that is probably too large for suburban gardens but could be used in shelterbelts and windbreaks on rural properties. Three specimens, grown together, would create an outstanding landscape feature in a large country garden.
Allocasuarina inophloia occurs on the Northern Tablelands, Northwest Slopes and Northwest Plains of New South Wales as well as southern Queensland.
The specimen illustrated was growing on sandstone near Warialda on the Northwest Slopes of New South Wales.
Propagate from seed and possibly cuttings.
