Description
Trees or shrubs. Leaves alternate , opposite or whorled , simple , pinnatifid , pinnate or bipinnate usually coriaceous , exstipulate . Inflorescence simple or compound , axillary or terminal , racemose or paniculate. Flowers usually actinomorphic , bisexual , solitary or paired in axils of bracts, rarely ebracteate. Perianth of 4 valvate , free or variously united tepals; each with a slightly expanded limb . Stamens 4, usually all fertile, opposite the tepals; filaments partly or wholly adnate to tepals, rarely free . Hypogynous glands usually present, 4, scale-like or fleshy , free or fused. Gynoecium of 1 carpel . Ovary superior , rarely perigynous , sessile or stipitate, 1-locular; ovules 1-many, variously inserted; style simple often persistent , often with the apex expanded as a pollen presenter; stigma small, terminal or subterminal. Fruit dehiscent or indehiscent , a woody or coriaceous follicle , drupe or an achene . Seeds 1 to many, usually endospermic.

Notes on delimitation
- Variously placed in earlier systems and often in Rosidae near to Elaeagnaceae. Others placed the family near to the Santalales, but usually considered basal.
- The Angiosperm Phylogeny Group place the family in a basal order Proteales where it is close to Platanaceae and Nelumbonaceae, both of which differ considerably morphologically, but many genes support this grouping.
Five Neotropical genera:
- Euplassa Salisb.
- Oreocallis R.Br.
- Orites R.Br.
- Panopsis Salis.
- Roupala Aubl.
- All five genera are native and four are endemic to the Neotropics; Orites also occurs in Australia.
- The leaves are often extremely variable and in species of Roupala are compound when young and simple when mature in some species, others may be consistently simple or compound.
- Distribution
-
Distribution in the Neotropics
- A largely southern hemisphere family consisting of 79 genera and ca. 1,700 species with Australia and southern Africa as its centers of greatest diversity.
- Eight genera and 84 species occur in the Americas distributed from Mexico to Chile and Argentina of which five occur in the tropical region.
- In the Americas the greatest diversity is in the Andes and eastern Brazil.
- Diagnostic
-
Distinguishing characters (always present)
- Secondary pollen presentation.
- 4-merous flowers.
- Perianth uniseriate of tepals.
- Swollen petiole bases common.
- Winged seeds common in all genera except Panopsis Salisb.

- Morphology Reproductive morphology Flowers Androecium Stamens
- Stamens 4, fused to the perianth and (in the Flora Zambesiaca area) lying inside the limb, attached opposite the perianth segments, the filaments largely adnate to the perianth segments and the anthers free
- Morphology General Scales
- Four small hypogynous scales often present on the receptacle between perianth and ovary
- Morphology Reproductive morphology Flowers Gynoecium Ovary
- Ovary superior, sessile or shortly stalked, often clothed with long hairs, unilocular with ovules variously numerous in 2 series, or 2, or solitary and orthotropous or amphitropous to anatropous; style (in the Flora Zambesiaca area) long, often exceeding the perianth, variously modified distally into a filiform to expanded pollen-presenter
- Note
- Two species of Macadamia are cultivated in Africa for their edible nuts, ‘Macadamia nuts’ or ‘Queensland nuts’. They are Australian shrubs to trees up to 10 m high with stiffly coriaceous leaves in whorls of 3 or 4 and whitish or pinkish flowers in spikes up to 30 cm long. M. integrifolia Maiden & Betche (‘M. ternifolia’ of some authors) has leaves in whorls of 3, the juvenile ones serrate but adult leaves usually entire or occasionally with up to 12 teeth on each side, ± cuneate at the base and with a petiole 4–15 mm long; the fruits are scarcely pubescent and usually do not dehisce on the tree. M. tetraphylla L.A.S. Johnson has leaves usually in whorls of 4, strongly serrate with 20–44 teeth on each side, the base rounded and petiole not exceeding 2 mm; the fruits are densely pubescent and usually dehisce on the tree. Both species are known to be cultivated in the Flora Zambesiaca area, but few specimens are available to determine which species is the more common. One collection of M. integrifolia from Mozambique, M: Quinta do Umbelúzi, 26 km W of Maputo (Lourenço Marques), 15.iv.1946, Gomes e Sousa 3428 (BR; COI; K), is said to be perhaps naturalized.
