The Western Australian Herbarium’s collections management system and census were set to read-only mode on 1 October 2025. Taxonomic updates published since this time are not being reflected in Florabase, herbarium collections, or Western Australia’s taxonomic names census (Nomos). Conservation listings displayed on Florabase may also be out of date. Please refer to DBCA’s Threatened species and communities webpage for the most recent Threatened and Priority Flora List, noting that recent taxonomic updates are similarly not included. Our database migration is moving to a staging phase. We thank you for your patience as we ensure the integrity of our biodiversity data, develop new workflows, and train staff to use the new systems. Please reach out to us if you have any questions or concerns.

The notice period started at 12:00 pm on Wednesday, 1 October 2025 +08:00 and will end at 12:00 pm on Friday, 1 January 2027 +08:00.

To 0.4 m high (often forming mats). Self supporting, or climbing; scrambling. Mesophytic. Not heterophyllous. Leaves medium-sized; alternate, or opposite; spiral (appearing whorled); with blades; ‘herbaceous’; petiolate; not connate; simple; not peltate; epulvinate. Leaf blades neither inverted nor twisted through 90 degrees; dorsiventral (in Australia); entire; flat; oblong (to circular). Mature leaf blades adaxially pubescent (stellate hairy), or glabrous; abaxially pubescent (stellate hairy), or glabrous. Leaves eligulate; with stipules. Stipules acute. Leaf blade margins entire; flat. Leaf anatomy. Hairs present, or absent; complex hairs present, or absent. Complex hairs stellate.

Reproductive type, pollination. Fertile flowers hermaphrodite. Unisexual flowers absent. Plants hermaphrodite. Plants homostylous.

Inflorescence and flower features. Flowers aggregated in ‘inflorescences’. Inflorescence many-flowered. Flowers in cymes. Inflorescences compound. The terminal inflorescence unit cymose. Inflorescences axillary. Flowers pedicellate; ebracteolate; small; regular; not resupinate; 5 merous; cyclic; tricyclic. Free hypanthium absent, or present (rarely). Hypogynous disk present, or absent (rarely). Perianth sepaline; (4–)5; 1 -whorled; isomerous. Calyx present; (4–)5; 1 -whorled; polysepalous (in Australia); imbricate; green, or white; non-fleshy. Sepals ovate. Corolla absent. Androecium present. Fertile stamens present. Androecial members definite in number (in Australia). Androecium 3–20. Androecial members free of one another, or coherent (rarely connate in bundles); 2 -whorled (usually), or 1 -whorled. Androecium including staminodes, or exclusively of fertile stamens. Staminodes fewer than stamens. Stamens 3–20; diplostemonous, or isomerous with the perianth; alternisepalous. Anthers separate from one another; dehiscing via longitudinal slits; tetrasporangiate. Fertile gynoecium present. Gynoecium 3–5 carpelled. The pistil 3–5 celled. Carpels reduced in number relative to the perianth, or isomerous with the perianth. Gynoecium syncarpous; synovarious to synstylovarious; superior. Ovary plurilocular; 3–5 locular. Gynoecium stylate. Styles 3–5; free. Stigmas 3–5; 1 - lobed. Placentation axile.
