Gazania serrata is a species of flowering plant in the family Asteraceae, native to the Northern Cape and Western Cape provinces, South Africa. [1]
The flowers are yellow or orange, and born on setose scapes. The flower's involucre is also setose, and a campanulate shape, with an obtuse base. The involucre has at least two rows of terminal bracts around its apex, and usually some scattered parietal bracts along its length. The innermost terminal involucre bracts have an acuminate shape.
The leaves are lanceolate and can be either simple, or pinnate with linear-to-oblanceolate lobes. The margins of the leaf lobes are usually irregularly serrated. The upper leaf surface is usually rough and slightly sticky. The lower surface is tomentose (white woolly).
In its growth form, G. serrata is a compact herbaceous perennial, and forms basal rosettes with only relatively short stems. The whole plant has a slightly sticky texture. [2]
Gazania serrata is very similar to a number of other Gazania species, including Gazania krebsiana , Gazania pectinata , Gazania linearis and Gazania rigida among others. Species boundaries between these are not clear, and they are frequently confused in practice.
In particular, it is very similar to Gazania rigida , which also has setose scapes and involucres, and occurs in similar areas of the south western Cape. However, G. serrata can usually be distinguished by its innermost terminal involucre bracts, which have acuminate tips (those of G. rigida have obtuse-acute tips). In addition, the slender G. serrata leaves usually having finely serrated margins, and an upper leaf-surface that is rough and viscous-sticky. [3]
Gazania is a genus of flowering plants in the family Asteraceae, native to Southern Africa.
Eurybia is a genus of plants in the family Asteraceae that were previously included in the genus Aster. Most species are native to North America, although one is also present in northern Eurasia. There are 23 species in the genus, including 1 natural hybrid. The name was first applied by Alexandre de Cassini in 1820. The name is derived from Ancient Greek εὐρύς (eurús), meaning "wide", and βαιός (baiós), meaning "few", perhaps in reference to the small number of relatively wide ray florets.
Gazania linearis is a species of flowering plant in the family Asteraceae, with thin linear leaves, native to South Africa.

Gorteria is a genus of small annual herbaceous plants or shrubs, with 8 known species, that is assigned to the daisy family. 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.
Corymbium is a genus of flowering plants in the daisy family comprising nine species. It is the only genus in the subfamily Corymbioideae and the tribe Corymbieae. The species have leaves with parallel veins, strongly reminiscent of monocots, in a rosette and compounded inflorescences may be compact or loosely composed racemes, panicles or corymbs. Remarkable for species in the daisy family, each flower head contains just one, bisexual, mauve, pink or white disc floret within a sheath consisting of just two large involucral bracts. The species are all endemic to the Cape Floristic Region of South Africa, where they are known as plampers.
Gazania krebsiana is a species of flowering plant in family Asteraceae. It is a low-growing herbaceous perennial native to Southern Africa, ranging from Angola, Zambia, and Mozambique to South Africa. It is one of some 19 species of Gazania that are exclusively African and predominantly South African - only Gazania krebsiana subsp. serrulata (DC.) Roessler ventures northwards from the Transvaal into tropical Africa.
Mairia crenata is a perennial herbaceous plant of mostly 2–15 cm (1–6 in) high that is assigned to the family Asteraceae. It has a woody rootstock of up to 5 cm (2 in) long, from which brown, fleshy roots develop. The five to eighteen, hard and leathery, spoon-shaped leaves are in one to three rosettes, have a distinct main vein, blunt or pointy tip, often dark red or blackish margins with rounded teeth and a ½–2 cm (0.2–0.8 in) long stalk-like foot, often initially somewhat woolly hairy, on particularly the lower surface and the main vein, but this is easily rubbed off the shiny surfaces. Each rosette produces mostly one, sometimes up to four, mostly rusty or whitish woolly hairy, brown or dark red inflorescence stalks, usually 1½–15 cm long, each with two to eight, initially woolly, line-shaped to oval bracts, the lowest up to 3 cm (1.2 in), decreasing size further up, and carrying mostly one, rarely up to three flower heads. The flower heads have a bell-shaped involucre with about 40 bracts, sixteen to thirty three violet to white ray florets of about 1¼–1⅞ cm long, and many yellow disc florets. The species flowers anywhere between February and December but only after a fire has destroyed the overhead biomass or serious disturbance. It is an endemic species that is restricted to the Eastern Cape and Western Cape provinces of South Africa.
Felicia canaliculata is a grayish green shrublet in the family Asteraceae that grows up to 40 cm (16 in) in height. It has narrow, awl-shaped leaves, relatively large flower heads with approximately a dozen light purple to white ray florets encircling many yellow disc florets. It can only be found in the Western Cape province of South Africa.
Felicia amoena is a variably hairy, sometimes glandular, biennial or perennial plant, of about 25 cm (10 in) high, that is assigned to the family Asteraceae. It is somewhat woody at its base, roots at the nodes if these contact the soil, and has ascending branches. The leaves are oppositely arranged along the stems at and just above a branching fork, further up the leaves alternate. The flower heads sit individually on up to 12 cm long stalks. They are 2–3 cm in diameter and consist of about twelve to twenty five heavenly blue ray florets that surround many yellow disc florets. Three subspecies have been recognised, that differ in width of the leaves and the involucral bracts, the size of the heads and number of ray florets and in having glandular hairs. These can be found in coastal sands and inland areas in the Western Cape and Eastern Cape provinces of South Africa. Flower heads can be found from June till October.
Mairia petiolata is a tufted, variably hairy, perennial plant of up to 15 cm (6 in) assigned to the family Asteraceae. Its leaves are in a ground rosette, and have a stalk of mostly 2–5 cm long and an inverted egg-shaped to elliptic, 61⁄2–9 cm (2.6–4.6 in) long and 2–3 cm wide leaf blade, with a toothed margin. It mostly has two flower heads at the tip of the branches of each erect, dark reddish brown scape. The flower heads have a bell- to cup-shaped involucre that consists of 20–24, purplish, overlapping bracts in 3–4 whorls. These protect 12–16 pink, ray florets, surrounding many yellow disc florets. This species was only seen flowering once, in December. It is known from one location in the Langeberg, Western Cape province of South Africa.
Mairia robusta is a tufted, white-woolly, perennial, herbaceous plant of up to 30 cm (1 ft) high, that is assigned to the family Asteraceae. It has large, robust, hard and leathery leaves, with a white woolly hairy, nontransparent underside, while the felty hairs on the top are lost with age. Only at a few occasions, flowers have been observed, in June, October and December, always after a fire. The flower heads sit individually at the tip of white-woolly scapes, with 14–16 purplish pink to white ray florets surrounding a yellow disc. M. robusta is an endemic species that is restricted to rocky mountain slopes in the Western Cape province of South Africa.
Gazania lichtensteinii is a species of flowering plant in the family Asteraceae, native to South Africa and Namibia. On the SANBI Red List, it is listed as "safe".
