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.

Habit and leaf form. Trees, or shrubs, or lianas (Australian species); evergreen (mostly), or deciduous. Partially parasitic. On roots of the host. Leaves cauline. Stem internodes solid. Self supporting, or climbing. Mesophytic. Leaves alternate; distichous; petiolate (hairy); non-sheathing; simple. Leaf blades entire (turning a characteristic yellow-green on drying); narrowly elliptic to ovate; pinnately veined; cross-venulate; attenuate at the base (to shortly attentuate). Leaves without stipules. Leaf blade margins entire. Leaf anatomy. Hairs present, or absent. Extra-floral nectaries absent. Stem anatomy. 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 spikes. Inflorescences axillary. Flowers sessile; bracteate (subtending each flower, small, lanceolate, rachis and bracts densely hairy, persistent, caducous). Bracts persistent, or deciduous. Flowers ebracteolate; small; fragrant; regular; 4 merous, or 5 merous; cyclic; tetracyclic. Free hypanthium present (B). Hypogynous disk present; of separate members (alternating with the stamens). Perianth with distinct calyx and corolla; 4(–5); 2 -whorled; isomerous. Calyx present; 4, or 5; 1 -whorled; gamosepalous; lobulate, or blunt-lobed; open in bud; cupuliform; regular; persistent; non-accrescent. Corolla present; 4; 1 -whorled; gamopetalous; valvate; urceolate; regular; greenish white, or yellow. Androecial members definite in number. Androecium 4–5. Androecial members free of the perianth, or adnate; all equal; free of one another (more or less adherent at the base); 1 -whorled. Androecium exclusively of fertile stamens. Stamens 4(–5); all more or less similar in shape; isomerous with the perianth; opposite perianth segments. Anthers dehiscing via longitudinal slits; tetrasporangiate. Gynoecium 2–5 carpelled. The pistil 1 celled. Carpels reduced in number relative to the perianth to isomerous with the perianth. Gynoecium syncarpous; eu-syncarpous; superior. Ovary unilocular; 1 locular; sessile. Gynoecium stylate. Styles 1; attenuate from the ovary; apical; shorter than the ovary at anthesis. Stigmas 1; capitate. Placentation basal, or free central. Ovules in the single cavity 1; pendulous, or ascending; non-arillate; anatropous.

Fruit and seed features. Fruit fleshy; indehiscent; a drupe; 1 celled; 1 locular; 1 seeded. Seeds endospermic. Endosperm oily. Seeds without a testa. Embryo well differentiated. Cotyledons (2–)3, or 4. Testa lacking.
