In an effort to deal with the high number of requests to VicFlora we have moved the maps into a new subdomain. If the maps do not work, it might be that your browser is still trying to connect to the old map server. Clearing the browser's cache should clear that up. We hope that this change, together with other changes we made in the last few weeks, will bring about a positive change in user experience for VicFlora. Thanks to all our users for hanging in there.

Annual or perennial herbs, often with a thickened taproot, glabrous or with axillary hairs. Leaves alternate, rarely opposite, usually sessile, simple, more or less fleshy; stipules absent. Inflorescence a terminal head-like cymose panicle. Flowers bisexual; sepals 2, fused at base; petals usually 5, fused at base; stamens usually numerous; ovary semi-inferior, 1 locular; ovules numerous; style cleft into 3–7 stigmatic arms. Fruit a circumsciss capsule.

1 genus with 116 species, worldwide, more common in tropic and subtropic regions.

A phylogenetic study of Portulacineae has found Victorian genera previously included in this family (i.e. Claytonia, Montiaand Calandrinia) to be better placed in a separate family, Montiaceae (Nyffeler & Eggli 2010).
