Osteospermum burttianum B.Nord. | |
Osteospermum burttianum is a species of plant from South Africa.
This shrublet is densely leafy and hairless. It grows up to 1 m (3.3 ft) tall. [1]
The hairless leaves are attached directly to the stems and are alternately arranged. They have a distinct midrib and the margins are either finely toothed or rough with small, brownish hairs. [2] They have a leathery texture. [3]
Flowers are most common between December and May. [3] Flowers may, however, be present until August. They are yellow in colour. [1] They grow in solitary capitula and are heterogamous. They grow on stalks that are 3–10 cm (1.2–3.9 in) long with 1-3 bract-like leaves. [2]
The involucre has a diameter of 10–15 mm (0.39–0.59 in) and is made of 8-13 narrow bracts. They have short. dark-tipped glandular hairs and net-like veination. [2]
The ray florets are female. There are 8-11 of them per flowerhead. The tube lobes are somewhat oval shaped and crested at the tips. They lack a midvein. The ovary is a narrow hairless and two-veined oblong. [2] In the male florets, the stamen are 2 mm (0.079 in) long. The style is sterile and tipped with a cone surrounded by a fringe of short hairs. [2]
This plant produces obscurely ribbed achenes (dry fruit containing a single seed) [1] They are 5–7 mm (0.20–0.28 in) long. [3]
This species is endemic to the Langeberg Mountains in the Western Cape of South Africa. It has a range of less than 500 km2 (190 sq mi), in which two populations occur. [1] [4] It prefers steep rocky sandstone slopes. [3] It is found on south facing slopes at an altitude of over 1,000 m (3,300 ft). [2]
This species is named after B.L. (Bill) Burtt in honour of his contributions to the knowledge of South African phytogeography and the Asteraceae family. [2]
While Osteospermum burttianum does not currently experience any threats, its small range means that it is currently classified as rare by the South African National Biodiversity Institute. [4]
Mimetes chrysanthus is an evergreen, upright shrub of 1½–2 m high that has been assigned to the family Proteaceae. It has green, slightly stalked oval leaves of 3–4½ cm (1.2–1.8 in) long and 1–1¾ cm (0.4–0.7 in) wide. The inflorescences are near the tip of the branches, cylinder-shaped and consist of 50–70 densely cropped flower heads, each in the axil of a green leaf, consisting of 25–35 golden yellow, faintly sweet scented flowers. It is endemic to the Fynbos ecoregion of South Africa and is found in two locations, in the Western Cape province. The flowering season is from March to May or June, but flower heads sometimes occur in any other part of the year.
Phaneroglossa is a genus of plants that is assigned to the daisy family. It consists of only one species, Phaneroglossa bolusii, a perennial plant of up to 40 cm high, that has leathery, line- to lance-shaped, seated leaves with mostly few shallow teeth and flower heads set individually on top of long stalks. The flower head has an involucre of just one whorl of bracts, few elliptic, white or cream ray florets, and many yellow disc florets. It is an endemic species of the Western Cape province of South Africa. Flowering mainly occurs from November to January.
Felicia echinata, commonly known as the dune daisy or prickly felicia, is a species of shrub native to South Africa belonging to the daisy family. It grows to 1 m (3.3 ft) high and bears blue-purple flower heads with yellow central discs. In the wild, it flowers April to October.
Oedera capensis is a prickly shrublet belonging to the family Asteraceae. It has stems that branch only at the foot and are densely set over their entire length with narrowly triangular leathery leaves with a sharp tip at approximately right angles to the stem. At their tip are what at first sight appears to be a single flowerhead with yellow ray florets and yellow disc florets. In fact, these are mostly nine densely cropped heads, as is suggested by the nine domes of the "disc" of the composite head, the untidy arrangement of the ray florets, and becomes very clear when cutting through the composite head. It is an endemic of the south of the Western Cape province in South Africa.
Mimetes pauciflorus, the three-flowered pagoda, is an evergreen, shyly branching, upright shrub of 2–4 (6½–13 ft) high, from the family Proteaceae. It has narrowly to broadly oval leaves of 2½–4 cm (1.0–1.6 in) long and ¾–2 cm (0.3–0.8 in) wide, on the upper parts of the branches, the lower parts leafless with a reddish brown bark. The inflorescences at the top of the shoots are cylinder-shaped, 10–40 cm (4–16 in) long and contain forty to one hundred twenty densely crowded flower heads, at a steep upward angle, hiding a crest of very small, almost vertical leaves. The flower heads each consist of three, rarely four individual flowers. The flowers are tightly enclosed by four or five orange-yellow, fleshy, pointy, lance-shaped involucral bracts, and three orange-yellow, 4–5½ cm (1.6–2.4 in) long bracteoles. It grows on always moist, south-facing slopes in the southern coastal mountains of South Africa. Flowers can be found from August to November, with a peak in September.
Felicia dregei is an evergreen, glandular shrub of up to 11⁄2 m (5 ft) high, that is assigned to the family Asteraceae. It has flat, finely felty, grayish green, narrowly elliptic to lance-shaped leaves of up to 4 cm long and 8 mm wide, with an entire margin or here and there with up to ten teeth. The flower heads have about ten violet ray florets, encircling many yellow disc florets. This species grows in the Northern Cape and Western Cape provinces of South Africa.
Felicia nordenstamii is a flowering shrub in the family Asteraceae. It is found only in South Africa where it grows on limestone hills close to the sea on the southern coast. Felicia nordenstamii is a many-branched shrub growing up to 30 cm (1 ft) tall. The lower parts of the stems are covered in grayish brown bark and the upper stem has many crowded, upwardly angled, alternate leaves with long hairs on the lower surfaces. Large flower heads form at the tips of the branches, each about 41⁄2 cm across, with about thirty purplish blue ray florets surrounding many yellow disc florets.
Mairia coriacea is a perennial plant assigned to the family Asteraceae. It has broad, tough and leathery, evergreen leaves. These have a narrowed foot and an entire margin or a few shallow, irregular teeth. They grow in a rosette directly from the rootstock. The plant produces flower heads with one whorl of white to mauve ray florets around many yellow disc florets, with one or few on top of a dark reddish, woolly stalk. Flower heads appear after the overhead vegetation burnt down, often destroying the leaves in the process. It can be found in the southern mountains of South Africa's Western Cape province. It is called leather leaves in English.
Felicia annectens is an annual plant of up to about 25 cm (10 in) high, that is assigned to the family Asteraceae. The lower leaves are opposite and the higher leaves alternate. The bloated involucre consists of very broad, hairless bracts. These protect up to ten, short, bluish ray florets that encircle yellow, partly sterile disc florets. The heads sit individually on top of up to 6 cm long stalks. The species was considered extinct after no observations were made after 1915, but was rediscovered in the 21st century. It occurs in the Western Cape province of South Africa.
Felicia westae is a sparsely branched shrub growing up to 40 cm tall, that is assigned to the family Asteraceae. The lower parts of the stems have lost their leaves and the upper part has many crowded, upwardly angled and curved, alternate leaves pressed against the stem, with the edges curled inward. The flower heads form at the tips of the branches, each about 31⁄3 cm across, with about twenty purplish blue ray florets surrounding many yellow disc florets. It is only known from a small area in the Eastern Cape province of South Africa.
Mairia burchellii is a tufted perennial plant of up to 15 cm (6 in) assigned to the family Asteraceae. It has narrow leaves of up to 5 mm (0.20 in) wide, with single main vein and an entire margin. Flower heads only occur after a fire has destroyed the standing vegetation, mostly in November or between February and June. The flower heads sit individually or with a few on the tip of a purplish stalk, with a few narrow bracts, and consist of a row of pinkish ray florets around many yellow disc florets. It can be found in the southwest of the Western Cape province of South Africa.
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.
Mairia hirsuta is a tufted perennial, herbaceous plant of up to 40 cm high, that is assigned to the family Asteraceae. Most of its narrow to broad elliptic or inverted egg-shaped leaves are part of the basal rosette, have margin that is rolled under, with rounded or pointy teeth or with some peg-like extensions, lightly woolly on the upper surface and densely woolly on the underside, but always the green remains visible. Flower heads have been found from July to November, mostly after a fire or when the soil has been disturbed. The species can be found in the southern mountains of the Western Cape province of South Africa.
Felicia clavipilosa is an upright, richly branched shrub of up to 60 cm (2 ft) high, that is assigned to the family Asteraceae. It has alternately arranged leaves, and flower heads with 3–4 whorls of involucral bracts with many yellow disc florets in the centre. Very characteristic for the species are the short club-shaped hairs on its fruits. There are two subspecies. Subsp. clavipilosa has narrowly lance-shaped entire leaves with one vein and pale mauve ray florets. Subspecies transvaalensis has lance-shaped leaves with one or three veins and white ray florets. The species occurs in southern Africa, with subsp. clavipilosa having a western distribution in Zambia, Zimbabwe, Namibia, Botswana and South Africa, and subsp. transvaalensis restricted to the east, from Zimbabwe, through Botswana to South Africa. The subspecies transvaalensis is sometimes called pokkiesblom in Afrikaans.
