Tromotriche is a genus of plant in family Apocynaceae. It is native to southern Africa. [1] [2] [3]
Tromotriche was first described as a genus in 1812, and its Greek name refers to the quivering hairs that surround the lobes of its flowers ("tromo-" = "trembling"; "-trichos" = "hair").
The soft stems of Tromotriche species are obtusely, roundly four-angled (in cross section). Low, rounded mounds run along the edges of the angles, and leaf remnants are not visible. The stem surface is soft but often slightly rough.
The varied flowers appear along the stems, and often have the characteristic hairs on the outsides of the lobes.
This genus is restricted to the western (winter rainfall) regions of South Africa & Namibia. Its natural range closely mirrors that of the related genus Quaqua . The Tromotriche species in the north of its range tend to inhabit rocky quartz flats; while the three species in the south are each restricted to a small spot within the sandstone Cape Fold mountain ranges.

Stapeliinae is a subtribe of flowering plants within the tribe Ceropegieae of the subfamily Asclepiadoideae of the family Apocynaceae. The subtribe comprises about 35 genera, including both the stem-succulent "stapeliads" and the horticulturally popular genera Brachystelma and Ceropegia. The largest number of genera are native to Africa, but a more limited number of genera are widespread in Arabia and Asia. Historically, a similarly circumscribed taxon was treated as a separate tribe, Stapelieae.
Stapelia is a genus of low-growing, spineless, stem succulent plants, predominantly from South Africa with a few from other parts of Africa. Several Asian and Latin American species were formerly included but they have all now been transferred to other genera. The flowers of certain species, most notably Stapelia gigantea, can reach 41 cm (16 inches) in diameter when fully open. Most Stapelia flowers are visibly hairy and generate the odor of rotten flesh when they bloom.
The genus Huernia consists of perennial, stem succulents from Eastern and Southern Africa and Arabia, first described as a genus in 1810.
Calyceraceae is a plant family in the order Asterales. The natural distribution of the about sixty species belonging to this family is restricted to the southern half of South America. The species of the family resemble both the family Asteraceae and the Dipsacaceae.
Symphyotrichum is a genus of over 100 species and naturally occurring hybrids of herbaceous annual and perennial plants in the composite family, Asteraceae, most which were formerly treated within the genus Aster. The majority are endemic to North America, but several also occur in the West Indies, Central and South America, as well as one species in eastern Eurasia. Several species have been introduced to Europe as garden specimens, most notably New England aster and New York aster.
Duvalia is a succulent plant genus in the subfamily Asclepiadoideae, in the family Apocynaceae (dogbane).
Otholobium is a genus of flowering plants in the pea family with over 50 named species, but several also remain undescribed sofar. Species may be herbaceous perennials, subshrubs, shrubs or small trees. The alternately set leaves are accompanied by stipules and mostly consist of three leaflets, sometimes just one. The inflorescences are on short or long stalks in the axils of the leaves. Within the inflorescences, the pea-like flowers occur in groups of three, rarely of two, subtended by a bract, and each individual flower also is subtended by a narrow bract. The petals may be white, pink, purple or blue, often with a differently colored nectar guide, that may sometimes even be yellow. The seedpods contain just one, black, dark or light brown seed. Most species are restricted to the Cape provinces of South Africa, but some occur at higher elevations in eastern Africa. Charles Stirton erected the genus in 1981. The species in South America will probably be segregated, because these are not sufficiently related to the African species.
Tridentea is a genus of succulent plant in the family Apocynaceae, endemic to southern Africa.
Leucospermum cordifolium is an upright, evergreen shrub of up to 1½ m (5 ft) high from the Proteaceae. The flower heads are globe-shape with a flattened top, 10–12 cm (3.9–4.7 in) in diameter, and are carried individually or with two or three together mostly at a right angle to its branch. The perianth is 3–3½ cm long, yellow, orange or crimson in color. From each flower emerges a 4½–6 cm (1.8–2.4 in) long style sticking out horizontally but curving upwards near the obliquely, shell-shaped, thicker pollen presenter. This gives each head the appearance of a pincushion. Its common name is ornamental pincushion in English and bobbejaanklou in Afrikaans. It flowers between the middle of July and the end of November. It naturally occurs near the south coast of the Western Cape province of South Africa. Varieties and hybrids of this species are used as cut flower and garden plant.
The genus Quaqua falls within the tribe of plants known collectively as stapeliads. All stapeliads, including Quaqua, are Old World stem succulents.
Pelargonium peltatum is a scrambling perennial plant with five shallow or deeply 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 the Cape Provinces of South Africa. In its home range, it flowers year round but most vigorously from August to October.
Stapeliopsis is a genus of succulent plants in the family Apocynaceae, native to southern Africa.
Piaranthus is a succulent plant genus in the subfamily Asclepiadoideae, in the family Apocynaceae.
Orbea is a genus of flowering plants of the family Apocynaceae, first described as a genus in 1812. It is native to Africa and the Arabian Peninsula.
Pectinaria is a genus of plants in the family Apocynaceae, first described as a genus in 1819. The entire genus is endemic to South Africa.
Stapelia hirsuta, common name starfish flower or carrion plant, is a species of flowering plant belonging to the family Apocynaceae.
Leucospermum cordatum is an evergreen, creeping shrublet of about 20 cm (8 in) high from the family Proteaceae. It has pale cream flower heads, from which pink flushed styles emerge, the whole reminiscent of a pincushion. Its common name is heart-leaf pincushion in English. It flowers between July and December but the peak of the flowering period is from September to November. It is an endemic species, that is only known from two locations close to each other in the Western Cape province of South Africa.
Duvalia vestita is a small succulent plant species, in the family Apocynaceae, indigenous to the southernmost part of the Western Cape Province, South Africa.
