Synonyms:	Calomeria africana (S. Moore) Heine Humea africana S. Moore
Common names:
Frequency:	Locally common
Status:	Native
Description:	Much-branched shrubby perennial, up to 1 m tall. Leaves sessile, oblong-ovate, up to 1.5 × 1 cm, 3-veined from the base, densely grey velvety on both surfaces. Capitula in terminal, many-headed corymbose cymes. Involucral bracts 5-seriate, ovate-oblong, 2.5 mm, pale yellow or rarely purplish. Florets bright yellow; flowerheads turning straw-coloured when older.
Notes:	Although this species is still listed in most taxonomic databases under the genus name Calomeria, other sources list Calomeria as a monotypic genus from Australia with the single species C. amaranthoides Vent, a shrub-like plant that bears little or no resemblance to C. africana.
