Viola decumbens | |
Viola decumbens is a perennial plant with a woody base that is assigned to the violet family. It has linear leaves and stipules. The bilaterally symmetrical purple flowers have five petals and a spur. It grows in fynbos and is an endemic species of the southern Western Cape province of South Africa, where it is called wild violet, a name used for other species elsewhere in the world.
Viola decumbens is a small shrub with very fine granules on its green parts, and a woody base. The erect branching stems are up to 25 cm (9.8 in) high. It carries alternately set, slightly succulent, linear, green leaves 15–25 mm (0.59–0.98 in) long and ½—2 mm (0.02—0.08 in) wide with a pointed tip and an entire margin. The bracts (or stipules) to the right and left of the foot of the leaf proper are also linear, clinging to the leaf blade (or adnate), and with a small tooth on each side at the base. [1] The somewhat scented, nodding flowers [2] grow individually from the leaf axils on long flower stalks (or pedicels) so the flowers are above the leaves, with two small bracts almost opposite each other in the upper part of the stalk. The five sepals are narrowly oval in shape with a pointed tip and are 3–5 mm (0.12–0.20 in) long. The five petals are purple or violet, veined, with the four upper ones oblong and 5–10 mm (0.20–0.39 in) long, the lower one shorter and connected to a 2–5 mm (0.079–0.197 in) long, tube-shaped, blunt spur. The orange anthers hang together (in jargon connivent), and two have extensions that reach into the spur and produce nectar. The ovary is globe-shaped, and later develops into an oval capsule 5–9 mm (0.20–0.35 in) long. The capsule contains oval yellow seeds 3 millimetres (0.12 in) long, with very fine granules. [1] Viola decumbens flowers from July right through to December in the southern hemisphere. [2]
The species was first described by Carl Linnaeus the Younger in 1782. [1] New research suggests it belongs to the section Xylinosium, together with two species from the Mediterranean: V. arborescens and V. saxifraga . [3] The species name decumbens refers to the fact that the stems are creeping at their base. [4]
Viola decumbens occurs only in the extreme south of the Western Cape, for instance in the Kogelberg and Hottentots Holland Mountains. It prefers moist sandy soils on low altitude slopes. [2]
Eremophila nivea, commonly known as silky eremophila, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. In nature it is a rare shrub with hairy branches and leaves, and blue, purple or violet flowers.
Protea eximia, the broad-leaved sugarbush, is a shrub that may become a small tree, which occurs in mountain fynbos on mainly acidic sandy soils; the species was very well known under its old name of Protea latifolia. The flowers have awns that are covered in purple-black velvety hairs, and are contained within a series of rings of involucral bracts that have the appearance of petals. The fruit is a densely hairy nut, many of which are inserted on a woody base. The flowers are borne terminally on long shoots, and have a tendency to become very untidy as they age.
Eremophila bowmanii, also known as silver turkeybush, Bowman's poverty bush and flannel bush, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to New South Wales and Queensland in Australia. It is a low to medium, spreading shrub with silvery-grey, hairy foliage and blue to lilac flowers, and sometimes grows in dense thickets with mulga.
Pelargonium peltatum is a scrambling perennial plant with shallow or deeply five lobed, circular to heart-shaped, somewhat fleshy leaves, sometimes with a differently coloured semicircular band, that has been assigned to the cranesbill family. It carries umbel-like inflorescences with 2–10, white to mauve, bilateral symmetrical flowers, each with a "spur" that is merged with the flower stalk. It is known by several common names including ivy-leaved pelargonium and cascading geranium. It is native to southern and eastern South Africa. In its home range, it flowers year round but most vigoriously from August to October.
Spergularia macrotheca is a species of flowering plant in the family Caryophyllaceae known by the common name sticky sandspurry. It is native to western North America from British Columbia to Baja California, where it grows in many types of moist coastal and inland habitat, often in alkaline and saline substrates. It may be found in marshes, alkali flats, beaches, meadows, seeps, and vernal pools. It is a perennial herb producing a narrow stem up to 40 centimeters long with a woody, thickened base and taproot. They may grow erect or prostrate across the ground. It is covered in sticky glandular hairs, especially in the inflorescence. The stems are lined with fleshy linear leaves, sometimes tipped with spines. The leaves are accompanied by triangular stipules up to a centimeter long each. Flowers occur in clusters at the end of the stem as well as in leaf axils. The small flowers have five pointed sepals and five oval white to lavender-pink petals. The fruit is a capsule containing tiny reddish brown, winged seeds.
Pelargonium cucullatum is a hairy, upright, branching, perennial shrub, of 1–2 m (3.3–6.6 ft) high, that has been assigned to the cranesbill family. It sprouts new stems from the underground rootstock and becomes woody at its base. It has alternately set, sometimes slightly succulent leaves crowded near the top of the branches, with leaf stalks and flat to hood-shaped leaf blades, with a rounded broad triangular to kidney-shaped outline of about 4–5.5 cm long and 5–9 cm wide, often somewhat incised, the margin with irregular teeth. The white to purplish red, 5-merous, somewhat mirror symmetrical flowers grow in umbel-like clusters, and each contain mostly 7 fertile stamens and 3 infertile staminodes of different length. P. cucullatum has been cultivated as a garden ornamental and house plant since the 17th century. It has been used to breed many modern pelargonium hybrids, notably the Regal pelargoniums. It is called hooded-leaf pelargonium or herba althaea in English and wildemalva in Afrikaans.
Viola calcarata is a species of genus Viola that grows on mountains of south-eastern Europe. It is commonly known as long-spurred violet or mountain violet. It is a herbaceous flowering perennial plant.
Eremophila campanulata, commonly known as bell-flowered poverty bush, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to a small area in central Western Australia. It is a small, low, densely branched shrub with small leaves and purple or lilac flowers. Its most distinctive feature is the dark purple sepals at the base of the flowers.

In the wild it grows in moist grassland, forest glades and margins, at altitudes between 1200 and 3400 m (3900–11.000 ft), in eastern Africa, from South Africa to Ethiopia, in Cameroun and Nigeria, and on Madagascar and Bioko. Vernacular names are bezongozongo in Madagascar, and dukunsha in Ethiopia.
Pelargonium luridum, locally called variable stork's bill, is a medium high, tuberous herbaceous perennial geophyte, belonging to the Stork's bill family, with white to pink, slightly mirror symmetrial flowers in umbels on long unbranched stalks directly from the ground rosette that consists of few initially ovate, later pinnately incised or linear leaves, with blunt teeth around the margin. The variable stork's bill naturally occurs from South Africa to Angola, southern Congo and Tanzania.
