Service Notice

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 Conservation listings displayed on Florabase may also be out of date.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.

Scientific Description

Family Plumbaginaceae.

Habit and leaf form. Dwarf shrubs, or herbs. Perennial, or annual (rarely); plants with a basal concentration of leaves, or with neither basal nor terminal concentrations of leaves (densely leafy branches sometimes present). Young stems terete or winged. Helophytic, or mesophytic, or xerophytic. Leaves alternate; spiral; ‘herbaceous’, or leathery; petiolate to sessile; sheathing, or non-sheathing; simple; epulvinate. Leaf blades entire (lobed); pinnately veined, or palmately veined to parallel-veined. Leaves with stipules, or without stipules; without a persistent basal meristem. Stem anatomy. Nodes tri-lacunar. Secondary thickening developing from a conventional cambial ring, or anomalous.

Reproductive type, pollination. Fertile flowers hermaphrodite. Unisexual flowers absent. Plants hermaphrodite. Plants homostylous, or heterostylous. Entomophilous; via hymenoptera, via lepidoptera, and via diptera.

Inflorescence and flower features. Flowers aggregated in ‘inflorescences’. Inflorescence 1–8(-12) flowered. Flowers in spikes (which often form a 1-sided pedunculate cyme or panicle). The terminal inflorescence unit cymose, or racemose. Inflorescences scapiflorous, or not scapiflorous; terminal. Flowers subsessile; bracteate (bracts 3, the 2 outer ones small, the inner larger and embracing the flowers); bracteolate; small to medium-sized; regular; 5 merous; cyclic; tetracyclic. Free hypanthium absent. Hypogynous disk absent. Perianth with distinct calyx and corolla; 10, or 15 (rarely); 2 -whorled; isomerous, or anisomerous (rarely). Calyx 5, or 10 (rarely); 1 -whorled; gamosepalous (the lower part of the tube 5–10-ribbed, the ribs often extended; the upper part membranous or chartaceous, coloured, often greatly expanded towards the apex); entire, or lobed; valvate, or plicate in bud; infundibular, obconic or tubular; regular; persistent. Corolla 5; 1 -whorled; gamopetalous (divided nearly to the base or with a short tube); lobed; imbricate, or contorted; regular; white to yellow; fleshy, or not fleshy; persistent, or deciduous. Androecium 5. Androecial members adnate (to the corolla basally); free of one another, or coherent; 1 -whorled. Androecium exclusively of fertile stamens. Stamens 5; isomerous with the perianth; alternisepalous; all opposite the corolla members. Anthers dorsifixed, or basifixed; versatile, or non-versatile; dehiscing via longitudinal slits; introrse; tetrasporangiate. Gynoecium 5 carpelled. The pistil 1 celled. Carpels isomerous with the perianth. Gynoecium syncarpous; synovarious; superior. Ovary unilocular; 1 locular. Styles 5; free; apical. Stigmas 5; dry type; papillate; Group II type. Placentation basal. Ovules in the single cavity 1; pendulous (from a long, basally attached funicle); anatropous (or circinnotropous).

Fruit and seed features. Fruit dehiscent, or indehiscent; a capsule, or a nut. Seeds endospermic, or non-endospermic; winged. Embryo well differentiated. Cotyledons 2. Embryo straight. Seedling. Germination phanerocotylar.

Physiology, biochemistry. Aluminium accumulation not found. Photosynthetic pathway: C3.

Geography, cytology, number of species. Adventive. Australian states and territories: Western Australia. South-West Botanical Province.
