Family

Bentham, G. (1864) Flora Australiensis 2: 293. Type: Queensland, Burdekin River estuary, E. Fifzalan s.n.; lecto: MEL. Fide J. H. Ross (1985) Muelleria 6: 35.

Stem

Usually flowers and fruits as a shrub about 1-2 m tall, occasionally when smaller.

Leaves

Leaflet blades about 15-45 x 6-13 mm, leaflet stalks about 1.5-3 mm long. Leaflet apices ending in a needle-like spine. Compound leaf petiole absent or very short. Compound leaves difficult to discern and could easily be mistaken for whorled simple leaves. Stipules +/- linear, about 2-5 mm long.

Flowers

Flowers large, about 20 mm diam. in 2-5-flowered racemes. Stamens two, anthers brown, one anther longer than the other. Ovary densely clothed in long, white, straight hairs. Style green, about 5-7 mm long.

Fruit

Fruits clothed in white hairs, each fruit about 22-24 x 11 mm. Seeds about 4.5-5 x 4 mm. Funicle or caruncle green, about 2 x 1 mm.

Seedlings

Seed germination time 34 to 604 days. Cotyledons about 15-23 x 8-11 mm, bases cordate. First leaf simple, margin entire. Second leaf compound, pinnate with five leaflets but compressed so as to almost appear palmate but the terminal leaflet more than twice the size of the lateral leaflets. Leaflet apex aristate, the tip about 2 mm long. At the tenth leaf stage: at first sight the leaves appear to be in clusters on the stem but closer examination reveals that the clusters are in fact digitately compound leaves with 6 or 7 leaflets and lacking a compound leaf petiole. Leaflets variable in size, mainly obovate, apex subulate, base cuneate to attenuate, 1.4-4 x 0.5-1.2 cm, middle leaflet largest. Stipules linear, about 3 mm long. Lateral veins forming loops well inside the blade margin.

Distribution and Ecology

Endemic to Queensland, occurs in CYP, NEQ and CEQ. Altitudinal range from 100-550 m. Grows in a variety of vegetation types including open forest and heath but sometimes found in vine thickets and monsoon forest.
