Service Notice

The Western Australian Herbarium’s collections management system, WAHerb, and DBCA’s flora taxonomic names application, WACensus, have been set to read-only mode since 1 October 2025. Recent taxonomic changes are not currently being reflected in Florabase, herbarium collections, or the census. Due to the rapidly approaching holiday season and associated agency and facility soft closures, along with the substantial work involved in data mapping, cleaning, and verification, the migration to the new collection management software is not expected to occur before 1 March 2026, when a further update will be provided. Please reach out to us if you have any questions or concerns.

The notice period started at 9:45 am on Friday, 12 December 2025 +08:00 and will end at 12:00 pm on Monday, 2 March 2026 +08:00.

Scientific Description

Family Lauraceae.

Habit and leaf form. Trees, or shrubs; evergreen; bearing essential oils, or without essential oils; leptocaul. Mesophytic. Leaves alternate; spiral; leathery; petiolate; non-sheathing; gland-dotted; aromatic; simple. Leaf blades entire; pinnately veined; cross-venulate. Leaves without stipules; without a persistent basal meristem. Stem anatomy. Nodes unilacunar (with two traces). Secondary thickening developing from a conventional cambial ring.

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

Inflorescence and flower features. Flowers aggregated in ‘inflorescences’; in cymes. Inflorescences compound (the cymes arranged in axillary racemes or panicles or pseudo-terminal panicles). The terminal inflorescence unit racemose, or cymose. Inflorescences axillary; with involucral bracts, or without involucral bracts. Flowers pedicellate, or sessile; small; fragrant, or malodorous, or odourless; regular; 3 merous; cyclic. Free hypanthium present. Hypogynous disk present, or absent. Perianth of ‘tepals’, or sepaline (relatively undifferentiated); 6; 2 -whorled; isomerous (3+3); joined (connate towards the base into a conical or ovoid tube); green, or white, or cream; fleshy, or non-fleshy; persistent, or deciduous; accrescent, or non-accrescent. Calyx 6. Androecium 12. Androecial members free of the perianth (on the hypanthium); all equal, or markedly unequal; free of one another; 4 -whorled. Androecium including staminodes (the innermost members staminodal). Staminodes 3. Stamens 9. Filaments appendiculate (the innermost whorl of fertile stamens with glands at the base). Anthers basifixed; non-versatile; dehiscing by longitudinal valves (opening from base to apex); introrse and extrorse (with the latter state confined to the third whorl); bilocular. Gynoecium 1 carpelled (ostensibly), or 3 carpelled (theoretically). The pistil 1 celled. Gynoecium ostensibly monomerous; of one carpel (or at least, ostensibly so); superior. Carpel stylate; apically stigmatic; 1 ovuled. Placentation apical. Ovary more or less sessile. Stigmas dry type; papillate; Group II type. Ovules pendulous; non-arillate; anatropous.

Fruit and seed features. Fruit fleshy. The fruiting carpel indehiscent; baccate. Fruit enclosed in the fleshy hypanthium (giving the appearance of an inferior fruit); 1 seeded. Seeds non-endospermic. Embryo well differentiated; straight. Seedling. Germination phanerocotylar, or cryptocotylar.

Physiology, biochemistry. Aluminium accumulation demonstrated.

Geography, cytology, number of species. Native of Australia. Not endemic to Australia. Australian states and territories: Western Australia, Northern Territory, and Queensland.
