Description:
Shrubs, rarely small trees; branchlets stellate-pubescent; leaves opposite and decussate, exstipulate, l-3-foliolate to imparipinnate, glabrous or stellate-tomentose.

Inflorescence axillary or terminal, few-to many-flowered cymes or flowers solitary; bracts small; flowers bisexual; sepals 4, free; petals 4, free, valvate or imbricate in bud, ovate, mostly apiculate, white or coloured; disk generally cushion-shaped, rarely deeply-lobed; stamens 8; filaments inserted at the base of the disk, often compressed, apex often abruptly narrowed, pubescent and tuberculate; anthers dorsifixed and versatile, often with apical appendages, introrsely and longitudinally dehiscent; gynoecium 4-carpellate; carpels basally fixed, mostly glabrous; ovules 2 per carpel; style inserted towards the apex of the adaxial margins of the carpels, lengthening during anthesis, mostly shorter than the stamens; stigma small and slightly wider than the style, to large and capitate.

Fruit of 1-4 basally fixed cocci, dehiscing apically and adaxially; exocarp coriaceous; seed mostly 1 per coccus, reniform to ovoid, endocarp cartilaginous and responsible for seed expulsion, ejected with the seed; outer testa membranous, inner thick, crustaceous.

Distribution:  Predominantly Australian genus of about 96 species with 4 species endemic to New Caledonia; 7 species in S.Aust.
