Oldenburgia paradoxa Less. | |
Oldenburgia paradoxa Less. is a species in the genus Oldenburgia , in the family Asteraceae.
In its habit Oldenburgia paradoxa is a remarkably dense, usually cushion-shaped, subshrub, typically growing in the form of a hemisphere. Plants will sometimes exceed a metre in height, but usually are much shorter, commonly 30 cm or so. The leaves are elliptical, alternate, and in appearance are typical of the genus, leathery, deep green above, and felted white below. They are suggestive of loquat leaves with the margins slightly rolled down. Young leaves are vividly white-felted all over; as they mature, they shed the felt on the upper surface, but retain the felt on their under-surfaces. [1]
Unlike the leaves of other members of the genus, the leaves of Oldenburgia paradoxa are crowded impenetrably closely at the branch tips around the periphery of the plant, and they are much smaller, being some 10 cm long. The branches have thick, corky bark that generally is not visible on an undamaged plant.
The flower heads are pedunculate to nearly sessile, but are exceptional among Oldenburgias, being borne among the leaves at the surface of the plant cushion; the other Oldenburgia species have tall peduncles that stand proud of the plant. The flower heads are about 5 cm in diameter, creamy, sometimes with a tinge of pink or purple. The flowerheads are solitary and terminal. [2]
The species is endemic to the mountains of the southern part of the Western Cape Province in South Africa. Its status is not clear; it always was uncommon and persists largely in mountain reserves. It grows in sandstone on cliffs, in rock crevices, and near mountain tops where it has little competition from other plants.
Leucospermum is a genus of evergreen upright, sometimes creeping shrubs that is assigned to the Proteaceae, with currently forty-eight known species.
Brunsvigia is a genus of African flowering plants in the family Amaryllidaceae, subfamily Amaryllidoideae. It contains about 20 species native to southeastern and southern Africa from Tanzania to the Cape Provinces of South Africa.
Protea neriifolia, also known as the narrow-leaf sugarbush, oleander-leaved sugarbush, blue sugarbush, or the oleanderleaf protea, is a flowering plant in the genus Protea, which is endemic to South Africa.
Oldenburgia grandis is a shrub or small, gnarled tree in the family Asteraceae. It occurs in the mountains around Makhanda in South Africa. It grows to a height of about 5m on sandstone outcrops. It has thick corky bark and large leaves clustered at the ends of branches. The leaves are dark green and leathery, reminiscent of loquat leaves, but generally a good deal larger. The emergent leaves are densely and completely felted with white hair. Most of the felt is lost as the leaf matures, but some persists on under-surfaces. Flowers are white or purplish and borne in large heads some 5- to 12 cm in diameter. The flowerheads are terminal; The same plant may bear solitary heads, plus heads borne in loose, irregular panicles. It is threatened by habitat loss.
Oldenburgia is a genus of flowering plant in the family Asteraceae. It contains four accepted species, including the commonly cultivated, near-endangered species Oldenburgia grandis (Thunb.) Baill. ; the petricolousOldenburgia paradoxa Less. (type-species); Oldenburgia intermedia Bond ; and Oldenburgia papionum DC. Oldenburgia herbacea (L.) Roxb., an unresolved name. They are endemic to South Africa, southern parts of western and eastern Cape.
Felicia amelloides, the blue daisy bush or blue felicia, is a hairy, soft, usually perennial, evergreen plant, in the family Asteraceae. It can be found along the southern coast of South Africa. It grows as ground cover and produces many very regular branches. It mostly grows to about 50 cm (1.6 ft) high, rarely to 1 m. The leaves are oppositely arranged along the stems, dark green in colour and elliptic in shape. The flower heads sit individually on up to 18 cm (7 in) long, green to dark reddish stalks. They consist of about twelve heavenly blue ray florets that surround many yellow disc florets, together measuring about 3 cm across. It is also cultivated as an ornamental, and was introduced in Europe in the middle of the 18th century.
Gazania rigens, sometimes called treasure flower, is a species of flowering plant in the family Asteraceae, native to coastal areas of southern Africa. It is naturalised elsewhere and is widely cultivated as an ornamental plant.
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.
Brabejum is a genus of a single species of large evergreen tree, Brabejum stellatifolium in the family Proteaceae, commonly called wild almond, bitter almond or ghoeboontjie. It is restricted in the wild to South Africa's Western Cape province, where it grows in thickets along the banks of streams. The plant is of botanical interest as being Africa's only member of the large grevilleoid subfamily. It is a bushy small tree with branches widely at ground level and numerous erect vigorous stems. Leaves grow up to 6 in (15 cm) long, narrow and bluntly toothed, appear at intervals along the branches, mostly in whorls of 6. In summer, the plant bears white flowers densely crowded on spikes arising from rusty buds at the leaf axils. The fruits to 2 in (5 cm) long, magenta to reddish brown, similar to an almond, appear in autumn. The nut is too bitter to eat; however, in earlier times it was boiled, roasted, and ground to make a "coffee" drink.
Leucospermum conocarpodendron is the largest species of the genus Leucospermum, reaching almost tree-like proportions of 5–6 m (16–20 ft) high with a firm trunk that is covered in a thick layer of cork that protects it from most fires. It has greyish or green narrow or broad inverted egg-shaped leaves with three to ten teeth near the tip and large yellow flowerheads, with firm, bent, yellow styles that stick far beyond the rest of the flower and give the impression of a pincushion. It is commonly known as the tree pincushion in English or goudsboom in Afrikaans. They naturally occur near Cape Town, South Africa.
Mimetes fimbriifolius, also called cowl pagoda or the fringed pagoda, is a species of plant in the family Proteaceae. It is a dense, rounded, multi-branched tree that grows up to 4 metres in height. This attractive and striking plant flowers all year round, and produces red and yellow branch-heads and inflorescences. The nectar-rich flowers are pollinated by sunbirds and the seeds are distributed and taken underground by ants before germinating. It is endemic to the Table Mountain range in the city of Cape Town, South Africa.
Leucospermum gerrardii is an evergreen, mat-forming shrub of mostly about 30 cm (12 in) high and up to 1 m (3.3 ft) in diameter, with branches originating from an underground rootstock. It has narrow leaves, sometimes with three or four teeth near the tip, and prominent, raised, netted to parallel veins. The flower heads are egg-shaped about 5 cm (2 in) in diameter and consist of at first yellow, later orange or scarlet perianths, and long styles reaching far beyond the perianth and together giving the impression of a pincushion. It is assigned to the family Proteaceae. It can be found in South Africa and Eswatini. It mostly flowers between September and November. The species is called dwarf pincushion or soapstone pincushion in English.
Mimetes stokoei, the mace pagoda, is an evergreen, upright, hardly branching, large shrub of 1–2 m high in the family Proteaceae. It has silvery, oval leaves of 5–8 cm (2.0–3.2 in) long and 2+1⁄2–4 cm (1.0–1.6 in) wide, with one large tooth supported by two smaller teeth near the tip, at an upward angle and somewhat overlapping each other. The inflorescences are set just below the growing tip, are cylinder-shaped, 10–12 cm (4–5 in) high, topped by a crest of small, more or less horizontal, pinkish-purple tinged leaves. It consists of several flower heads in the axils of golden leaves with a pinkish wash that form a hood shielding the underlying flower head. Each flower head contains eight to twelve individual flowers, with amber-colored styles topped by blackish purple pollen presenters and grey silky perianth lobes. It is endemic to the Fynbos ecoregion of South Africa, being confined to the Kogelberg mountain range. The mace pagoda was twice presumed extinct, but reappeared in its natural habitat from seed, after a wildfire several decades later.
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 1⁄2–2 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 1+1⁄2–15 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 1+1⁄4–1+7⁄8 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.

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.
