Disa purpurascens is a species of orchid found in South Africa (SW. Cape Prov.). It is also known as the early blue disa or the bloumoederkappie.
Plants are 200–250 mm (7.9–9.8 in) tall, growing from a tuber with a length of about 30 mm (1.2 in) and a diameter of about 10 mm (0.39 in). About 10 narrow, rigid leaves, about half as tall as the plant, grow from a basal rosette. The base of the plant is often surrounded by a sheath of old leaf fibers. [1]
This species flowers in October and November, producing an inflorescence of 1–7 sweetly scented flowers. Each flower has a blue hood and side wings, with a dark purple lip below. Yellow-green petals are found at the back of the hood. [2] While the flowers look similar to those of Disa graminifolia , they differ in having an upcurved lip margin and a conical spur. They also flower at different times of the year. [3]
While there is generally very little variation between plants, some white flowers have been observed. This has been suggested to be a recessive condition. [1]
This species has a fairly narrow distribution, growing in coastal regions between Cape Hangklip and Cape Agulhas. It is not thought to occur above 100 m (330 ft) above sea level. [1]
Agapanthus africanus, or the African lily, is a flowering plant from the genus Agapanthus found only on rocky sandstone slopes of the winter rainfall fynbos from the Cape Peninsula to Swellendam. It is also known as the lily-of-the-Nile in spite of only occurring in South Africa.
Disa is a genus of flowering plants in the family Orchidaceae. It comprises about 182 species. Most of the species are indigenous to tropical and southern Africa, with a few more in the Arabian Peninsula, Madagascar, and Réunion. Disa bracteata is naturalised in Western Australia, where the local name is "African weed-orchid."
Babiana is a genus of geophytes in the family Iridaceae with 93 recognized species as of March 2022. The leaves consist of a stalk and a blade that are at an angle to each other. The leaf blades are entire, laterally flattened and pleated, and often hairy. Each individual flower is subtended by two hairy or smooth bracts that are green in most species. The outer bract is often the largest of the two. In most species the bracts have a dry, brown tip, but in a few species it is entirely green or entirely dry when flowering or the outer bract is translucent and has a papery texture. The inner bract is forked or split all the way to its base. Each flower is without a pedicel, with six tepals that are merged at their base into a tube and form a perianth that is mirror-symmetrical in most species, with three anthers implanted where the perianth tube widens and that are, in almost every species, clustered at one side of the style. The style has three branches that widen towards the tip and the ovary is inferior. Flowers occur in almost every conceivable colour, many have markings on some of the tepals, and few star-symmetrical flowers have a centre that strongly contrasts with the free part of the perianth. The majority of these species are endemic to the west and southwest of South Africa, and southwestern Namibia, but one species occurs elsewhere in Namibia and South Africa and another species can be found in Botswana, Namibia, South Africa, Zambia and Zimbabwe. The genus name is derived from the Dutch word baviaan, referring to the Chacma baboon, Papio ursinus, that consumes the corms of plants in the genus. The genus is called bobbejaantjie in Afrikaans, meaning small baboon.
Mimetes cucullatus is an evergreen shrub with several, mostly not branching, upright stems of 1–2 m (3–7 ft) high, that has been assigned to the family Proteaceae. It is the most widespread and most common pagoda species that can cope with a relatively large range of environmental circumstances. It is known under several names including common pagoda in English and rooistompie in Afrikaans.
Disa bracteata, also known as the bract disa, leek orchid or the South African weed orchid is a species of orchid native to South Africa.
Moraea aristata is a species of flowering plant in the family Iridaceae. It is referred to by the common names blue-eyed uintjie or Blouooguintjie in Afrikaans.It is endemic to the city of Cape Town and is considered to be critically endangered.
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.
Ixia monadelpha, also known as the pied kalossie or bontkalossie, is an endangered species of geophyte found in wet sandy flats in the southwestern Cape of South Africa.
Disa ferruginea also known as the cluster disa, is a species of orchid from South Africa.
Felicia tenella is an annual, sometimes biennial, herbaceous plant that may be slightly woody at its base, of 5–70 cm tall, that is assigned to the family Asteraceae. The species is very variable in size and hairiness. Its branches may be erect or ascending, and the leaves are narrowly line-shaped, 2–5 cm long and about 1 mm (0.04 in) wide. The leaves have a callous tip, lack visible nerves, and are mostly rigidly ciliate. The flower heads sit individually at the tip of stalks, have an involucre of three whorls of bracts, and about thirty light blue ray florets surrounding many yellow disc florets. Four subspecies are recognised. The species naturally occurs in the Northern Cape and Western Cape provinces of South Africa.
Bartholina burmanniana, the spider orchid, is a species of deciduous, geophytic, flowering plant in the family Orchidaceae. It is one of two species within the Bartholina genus, the other being B. etheliae. The species’ common name refers to its spreading and deeply cut lip that is said to resemble a spider's legs. It is native to the Eastern and the Western Cape Provinces of South Africa, flowering from the end of August to the middle of October and peaking in September. This is one of the species sometimes referred to as "spider orchid".
Lobostemon montanus, the turquoise bush bugloss, mountain lobostemon or agtdaegeneesbos, is a South African species belonging to the forget-me-not family.
Lobostemon decorus, the Rooiberg healthbush, is a species belonging to the forget-me-not family. It is endemic to the Western Cape of South Africa.
Lobostemon echioides, the common healthbush, is the mostly widely distributed species in its genus. It is endemic to the Cape Provinces of South Africa, where it is found growing between Namaqualand and the Karoo and the Eastern Cape.
Lobostemon fruticosus, also known as the eightday healthbush or pyjamabush, is a species of medicinal plant endemic to the Cape Provinces of South Africa. It is considered to be ecologically and economically important but is declining due to overexploitation.
Babiana vanzijliae is a species of geophyte of 4–12 cm (1.6–4.7 in) high that is assigned to the family Iridaceae. It has leaves that consist of a sheath and a blade that are at an angle with each other. The leaf blades are narrow, sword- to lance-shaped and have a left and right surface, rather than an upper and lower surface. The leaf blades are pleated and covered in velvety hairs. The inflorescence contains three to five pale bluish mauve to yellow flowers, but the lower lateral tepals are yellow becoming pale around the edges, and with three stamens crowding under the upper lip. Flowering occurs from early August to the middle of September. The flowers emit a strong scent. B. vanzijliae grows along the Bokkeveld Escarpment near Nieuwoudtville in the Northern Cape province of South Africa.
Babiana sambucina is a species of geophyte of 8–30 cm (3.1–11.8 in) high that is assigned to the family Iridaceae. It has dense spikes of blue to violet-coloured, often fragrant flowers. There are two subspecies, B. sambucina subsp. longibracteata is restricted to a small area in the Northern Cape, B. sambucina subsp. sambucina grows in the Western Cape and Eastern Cape provinces of South Africa. Flowers are present in August and September.
Babiana mucronata is a perennial plant species that grows to about 5–18 cm (2.0–7.1 in) high and annually forms leaves and flowers from an underground corm. It is assigned to the iris family. It has a simple or branched, more or less upright spike of 3-12 dark to pale violet-blue, mirror-symmetrical flowers. Each flower consists of a perianth that is merged below into a funnel-shaped tube of 10–25 mm (0.39–0.98 in) long but splits into six unequal tepals.
