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.

Family Rutaceae.

Habit and leaf form. Under- shrubs; evergreen, or deciduous; bearing essential oils. Mesophytic, or xerophytic. Leaves small; alternate; leathery, or ‘herbaceous’; petiolate; non-sheathing; gland-dotted; aromatic; simple. Leaf blades entire; pinnately veined, or one-veined. Leaves without stipules, or with stipules. Stipules when present, intrapetiolar; represented by glands. Leaf blade margins revolute. Leaves without a persistent basal meristem. Leaf anatomy. Hairs present; complex hairs present. Complex hairs stellate (to lepidote). Stem anatomy. Nodes unilacunar, or tri-lacunar. Secondary thickening developing from a conventional cambial ring.

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

Inflorescence and flower features. Flowers aggregated in ‘inflorescences’; in heads (subtended by foliar bracts). The terminal inflorescence unit cymose, or racemose. Inflorescences terminal; compact. Flowers sessile; bracteate; small; fragrant; regular, or somewhat irregular. The floral asymmetry when noticeable, involving the perianth and involving the androecium (not K). Flowers usually 5 merous; cyclic. Floral receptacle developing a gynophore (associated with the disk), or with neither androphore nor gynophore. Free hypanthium absent. Hypogynous disk absent. Perianth with distinct calyx and corolla; 10; 2 -whorled; isomerous. Calyx usually 5; 1 -whorled; polysepalous, or gamosepalous (below); imbricate; regular; with the median member posterior. Corolla 5; 1 -whorled; polypetalous; slightly imbricate; regular, or unequal but not bilabiate. Petals narrow elliptic. Androecium 10. Androecial members free of the perianth; all equal, or markedly unequal; free of one another; 2 -whorled. Stamens 10 (exceeding petals); diplostemonous; alternisepalous. Filaments glabrous, or hairy (stellate-pilose). Anthers more or less basifixed; versatile; dehiscing via longitudinal slits; introrse, or latrorse; tetrasporangiate. Gynoecium 2 carpelled; apocarpous (carpels not apiculate); eu-apocarpous; superior. Carpel (1–)2–100 ovuled. Placentation of the free carpels marginal. Stigmas wet type, or dry type; papillate, or non-papillate; Group II type, or Group IV type. Ovules pendulous to ascending; epitropous; when two or more per cell, collateral, or superposed, or biseriate; arillate, or non-arillate; anatropous, or hemianatropous.

Fruit and seed features. Fruit fleshy, or non-fleshy; an aggregate. The fruiting carpel dehiscent, or indehiscent; baccate (cocci hemispherical). Seeds oblong to reniform; endospermic, or non-endospermic. Embryo well differentiated. Cotyledons 2. Embryo chlorophyllous, or achlorophyllous; straight, or curved, or bent. Seedling. Germination phanerocotylar, or cryptocotylar.

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

Geography, cytology, number of species. A genus of 3 species.
