Common name: Broom wheel-fruit.

Description:
Shrubs to 70 cm high, with slender erect almost virgate branches usually with decurrent ridges from the leaf bases when young; leaves linear, 5-20 X c. 1.5 mm, usually sharply acute, more or less angular-terete, erect to almost appressed to the stems.

male flowers with erect pedicels c. 1 mm long, 3-4 mm across at anthesis, with the calyx broadly lobed, with 9-12 anthers in 1 whorl; female flowers with pedicels rarely to 1 mm long, with the calyx distinctly lobed and acute, with 2 rarely 1 carpels each with a long stigma usually recurved onto the almost orbicular ovary.

Fruit usually bilobed in side view, more or less swollen around the seed, c.2 mm long; seeds ovate in side view, c. 1.5 mm long, covered with often undulate transverse ridges from the centre, with a flattened aril wrapped around much of the seed.

Taxonomic notes: The stiffly erect branches of some plants of G. australasicus give particularly male plants a similar appearance to those of G. thesioides which is, however, usually distinguished by decurrent ridges from the leaf bases along the internodes and the absence of uncinate leaf apices.
