Allocasuarina nana: is a member of the Casuarinaceae family and was previously known as Casuarina nana.
A common name for this species is Stunted She Oak but we feel that a more appropriate title should be Dwarf She Oak.
Allocasuarina nana is a small, dense shrub that will reach a height of less than 1.5 metres. The leaves are reduced to whorls of teeth around the stem. The Dwarf She Oak has 5 to 7 leaf-teeth in a whorl.
Allocasuarina nana is usually dioecious (male and female flowers on separate plants). The male flowers are carried in spikes on the ends of branches. When the flowers mature, pollen is released and spread by the wind. Female flowers are in globular heads on short stalks along branches. Pollinated female flowers develop into persistent, woody, globular cones. Each cone contains many small, winged nuts or samaras.
Allocasuarina nana is an attractive small shrub that could be grown as a foreground plant in a native garden bed. The Dwarf She Oak could also be used as a low, informal hedge. The species would make an excellent native substitute for the ubiquitous, slow-growing English Box in this situation.
Allocasuarina nana occurs in New South Wales and Victoria and usually grows in sandstone areas. The specimen illustrated is growing in the Box Vale Reserve near Mittagong in the Southern Highlands of New South Wales. We have also observed the Dwarf She Oak growing in the Blue Mountains, of New South Wales and in Deua National Park in southern New South Wales. In this latter location Allocasuarina nana covers hillsides.
Propagate from seed and possibly cuttings.
