Schistostephium griseum is a species of plant from southern Africa.
Schistostephium griseum is a perennial woody herb or shrub that grows up to 75 cm (30 in) tall. [2] It is covered in silky white hairs. The branches have a diameter of 1.5–5 mm (0.059–0.197 in). [3]
The leaves are alternately arranged. They are most common on young branches, but some also grow on the main branch. [3] They are pinnately with three to seven linear lobes and an entire margin. [2] [3] The margins are often thickened and roll inswards. [2] They sometime grow directly on the branches and sometimes have a midrib that lacks lamina at the base. When present, the laminas are more or less oval shaped and pinnately dissected. While the laminas have glands, these are often hidden by hairs. These hairs are the most dense along the midrib and veins. They are about 1 mm (0.039 in) long. [3]
Bright yellow flowers are present in December. They are disc-shaped and borne on long (10–20 cm (3.9–7.9 in)) brown-haired stalks. [2] Hairy bracts subtending the flowerhead are sometimes present. All the flowers are hermaphroditic. [3]
The involucre is broad (13–17 mm (0.51–0.67 in) and shallowly bell-shaped. It is made of about 45 bracts. They are variable in shape and size and are often translucent towards the tips. They are densely hairy below. The hairs are pale when they dry. [2]
The receptacle (the central part f the flower that holds the pollen) is hollow and domed.The anthers have inconspicuous collars and turn white when they dry. [3] The lobes are slightly rounded due to a dense layer of hairs. [2]
The fruits are achenes (dry and singe seeded fruits) sparsely covered with glands. They are 2–2.5 mm (0.079–0.098 in) long. Hairs are sparse, or more commonly absent. [3] There is no pappus. [2]
This plant is endemic to South Africa, Eswatini, Lesotho and Mozambique. [4] It grows in stony grassland at altitude of 250–1,300 m (820–4,270 ft). [2] [3] It is also found at the edges of forests. [3]
This species is considered to be of least concern by the South African National Biodiversity Institute. While it is declining in parts of its range due to habitat loss and degradation, it has a large enough range to not yet be at risk of extinction. [5]
Pachypodium brevicaule is a species of plant that belongs to the family Apocynaceae.
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.
Prostanthera spinosa, commonly known as spiny mintbush, is a shrub that is endemic to south-eastern Australia. It has mauve to white flowers, spiny stems and aromatic foliage.
Eremophila pinnatifida, commonly known as Dalwallinu eremophila is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is a spreading, rounded shrub with aromatic, deeply divided leaves and pale purple flowers which are white with purple spots inside. It is a rare plant, known only from a few areas near Perth.
Petrophile axillaris is a species of flowering plant in the family Proteaceae and is endemic to southwestern Western Australia. It is a shrub with pinnately-divided, sharply-pointed leaves, and spherical heads of hairy pink or grey flowers.
Serruria elongata or long-stalk spiderhead is a plant belonging to the protea family. It is an erect, hairless shrublet of 1–1½ m (3½–5 ft) high with densely set, alternate, finely divided leaves lower down the plant, with needle-like segments. On top of an up to 30 cm (12 in) long inflorescence stalk are several, loosely arranged heads of pin-like, densely silvery-haired flower buds, each of which opens with four curled, magenta pink corolla lobes. The species is endemic to the southern Western Cape province of South Africa. It flowers during the southern hemisphere winter and early spring, between June and September.
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.
Tephrosia glomeruliflora, or pink tephrosia, is a perennial (non-climbing) herb in the family Fabaceae, endemic to South Africa. It is also found on the eastern coast of Australia, in New South Wales and Queensland, where it is considered an environmental weed.
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.
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 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.
