Proteaceae

 King protea Protea cynaroides, from here.

Belongs within: Proteales.
Contains: Persoonioideae, Grevilleoideae, Conosperminae, Petrophile.

The Proteaceae are a family of flowering plants found primarily in southern Africa, Australia and South America, as well as in Asia and various parts of the Pacific. Many species have red or yellow flowers, generally bird-pollinated. The Proteaceae are divided between a number of subfamilies, of which the largest are the primarily African Proteoideae and the mostly Australian Grevilleoideae. For the most part, Proteoideae are characterised by indehiscent fruits and single flowers. Bellendena montana, a Tasmanian species that has been placed in its own subfamily, bears flowers in a mostly ebracteate raceme and has dry, indehiscent fruits with two wings. The Symphionematoideae, another small group found in south-eastern Australia, have bracteate inflorescences and dry, indehiscent fruits (Weston & Barker 2006).

Within the Proteoideae, the Conospermeae as listed below are supported as a clade by molecular analysis as well as by coherence of fertile anther loculi to the fertile loculi of adjacent anthers. The Proteeae are characterised by floral zygomorphy with the perianth being split into two lobes, the anterior tepal free or basally connate to the others and the three posterior tepals completely connate or almost so. The Leucadendreae are a diverse clade lacking clear morphological synapomorphies but united by molecular data. The Petrophileae are also primarily united by molecular data but may also be characterised by the production of the sugar pinitol (Weston & Barker 2006).

Characters (from Foreman 1995): Trees or shrubs. Stipules absent. Leaves spiral, rarely verticillate or opposite, simple or variously divided, often dimorphous; margin entire or toothed, sometimes spiny. Inflorescences axillary or terminal, ramiflorous or cauliflorous, with flowers in pairs, arranged in raceme- or cone-like inflorescences or in dense heads; peduncles present or absent. Bracts present, mostly small, often early caducous, sometimes large and woody. Flowers regular to very irregular, mostly bisexual, rarely unisexual. Tepals valvate, with expanded limb, often recurved, at first adhering to each other mostly becoming entirely free. Receptacle flat or oblique. Stamens 4, epipetalous; filaments usually relatively short; anthers erect, basifixed, mostly tetrasporangiate, dehiscing by longitudinal slits; connective prolonged or not. Disc mostly present, flat or oblique, annular or more or less horseshoe-shaped or with 4 free or variously fused hypogynous glands. Ovary superior, 1-locular, sessile or stipitate, often oblique. Style more or less expanded in upper part into pollen-presenter. Stigma mostly small, terminal or lateral. Ovules 1 or more, pendulous or laterally attached. Fruit dehiscent or indehiscent: follicle, drupe or small nut. Seeds winged or not; endosperm mostly absent; cotyledons thin or thick and fleshy.
