GorteriaGorteria is a genus of small annual herbaceous plants or shrubs that is assigned to the daisy family (Compositae or Asteraceae). It includes 12 species native to eastern and southern Africa, ranging from Ethiopia to South Africa. Like in almost all Asteraceae, the individual flowers are 5-merous, small and clustered in typical heads, and are surrounded by an involucre, consisting of in this case several whorls of bracts, which are merged at their base. In Gorteria, the centre of the head is taken by relatively few bisexual and sometimes also male, yellow to orange disc florets, and is surrounded by one complete whorl of 5–14 infertile cream to dark orange ray florets, sometimes with a few ray florets nearer to the centre. None, some or all of them may have darker spots at their base. The fruits remain attached to their common base when ripe, and it is the entire head that breaks free from the plant. One or few seeds germinate inside the flower head which can be found at the foot of plants during their first year. The species flower between August and October, except for G. warmbadica that blooms mostly in May and June. The species of the genus Gorteria can be found in Namibia and South Africa.
Gorteria diffusaGorteria diffusa is a highly variable, small annual herbaceous plant or rarely a shrublet that is assigned to the daisy family (Compositae or Asteraceae). Like in almost all Asteraceae, the individual flowers are 5-merous, small and clustered in typical heads, and are surrounded by an involucre, consisting of in this case several whorls of bracts, which are merged at their base. In G. diffusa, the centre of the head is taken by relatively few male and bisexual yellow to orange disc florets, and is surrounded by one complete whorl of 5–14 infertile cream to dark orange ray florets, sometimes with a few ray florets nearer to the centre. None, some or all of them may have darker spots at their base. The fruits remain attached to their common base when ripe, and it is the entire head that breaks free from the plant. One or few seeds germinate inside the flower head which can be found at the foot of plants during their first year. The species flowers between August and October. It is called beetle daisy in English and katoog (cat eye) in Afrikaans. It can be found in Namibia and South Africa.
Gorteria personataGorteria personata, the mini beetledaisy, is a small annual herbaceous plant in the daisy family (Compositae or Asteraceae). It is endemic to the Cape Provinces of South Africa. It is called bosduifdoring in Afrikaans.
List of Asteraceae of South AfricaAsteraceae or Compositae is a family of flowering plants (anthophytes) in the order Asterales. Asteraceae (commonly referred to as the aster, daisy, composite, or sunflower family), is a very large and widespread family, which includes over 32,000 currently accepted species, in over 1,900 genera (list) in 13 subfamilies. In terms of numbers of species, the Asteraceae are rivaled only by the Orchidaceae. Nearly all Asteraceae bear their flowers in dense heads (capitula or pseudanthia) surrounded by involucral bracts. When viewed from a distance, each capitulum may appear to be a single flower. Enlarged outer (peripheral) flowers in the capitula may resemble petals, and the involucral bracts may look like a calyx. The name Asteraceae comes from the type genus Aster, from the Ancient Greek ἀστήρ, meaning star, and refers to the star-like form of the inflorescence. The alternative name Compositae is still valid under the International Code of Nomenclature for algae, fungi, and plants. It refers to the "composite" nature of the capitula, which consist of a few or many individual flowers. Most members of Asteraceae are annual or perennial herbs, but a significant number are also shrubs, vines, or trees. The family has a cosmopolitan distribution, with species ranging from subpolar to tropical regions, colonizing a wide variety of habitats. The largest proportion of the species occur in the arid and semiarid regions of subtropical and lower temperate latitudes. 23,420 species of vascular plant have been recorded in South Africa, making it the sixth most species-rich country in the world and the most species-rich country on the African continent. Of these, 153 species are considered to be threatened. Nine biomes have been described in South Africa: Fynbos, Succulent Karoo, desert, Nama Karoo, grassland, savanna, Albany thickets, the Indian Ocean coastal belt, and forests. The 2018 South African National Biodiversity Institute's National Biodiversity Assessment plant checklist lists 35,130 taxa in the phyla Anthocerotophyta (hornworts (6)), Anthophyta (flowering plants (33534)), Bryophyta (mosses (685)), Cycadophyta (cycads (42)), Lycopodiophyta (Lycophytes(45)), Marchantiophyta (liverworts (376)), Pinophyta (conifers (33)), and Pteridophyta (cryptogams (408)). 329 genera are represented in the literature. Listed taxa include species, subspecies, varieties, and forms as recorded, some of which have subsequently been allocated to other taxa as synonyms, in which cases the accepted taxon is appended to the listing. Multiple entries under alternative names reflect taxonomic revision over time.
