100 PORTULACACEAE [1]

Dennis I Morris [2], Marco F Duretto [3]

Herbs or less commonly shrubs or subshrubs, often with a thick taproot, usually glabrous apart from axillary hairs in some genera. Leaves alternate, subopposite or opposite, sometimes rosetted at base, exstipulate, simple, entire, usually sessile. Inflorescence a few to many-flowered cymes or heads or cymose panicle, occasionally the flowers solitary, bracts leafy or scarious. Flowers bisexual, regular or slightly irregular. Sepals (actually bracteoles) 2, free or connate at the base, often slightly unequal, usually persistent. Petals (actually petaloid sepals) (2–)4–11, usually 5, free or shortly connate at the base, often ephemeral. Stamens 3-numerous, commonly as many as and opposite to the petals; filaments free or often connate at the base; anthers dithecal, dorsifixed, dehiscing by longitudinal slits. Ovary superior or semi-inferior, of 2–3(–9) carpels united to form a compound ovary with at first as many locules as carpels, the partitions disappearing early to form a unilocular ovary; ovules 3-many, on a basal or central placenta; style with 3–9 stigmatic branches. Fruit a capsule opening by 3 or 4 valves or circumscissile. Seeds 1-many, commonly ± lenticular, smooth and shining or tuberculate or colliculate.

A family of about 20 genera and 250 species; cosmopolitan in distribution with the main centre of development in the Americas. In Australia there are about 70 species in 7 genera. The Portulacaceae are placed in the large order Caryophyllales near Cactaceae (mainly the Americas).
