The Portulacaceae are a family of flowering plants, comprising 115 species in a single genus Portulaca. Formerly some 20 genera with about 500 species, were placed there, but it is now restricted to encompass only one genus, the other genera being placed elsewhere. The family has been recognised by most taxonomists, and is also known as the purslane family. It has a cosmopolitan distribution, with the highest diversity in semiarid regions of the Southern Hemisphere in Africa, Australia, and South America, but with a few species also extending north into Arctic regions. The family is very similar to the Caryophyllaceae, differing in the calyx, which has only two sepals.
Aloidendron dichotomum, formerly Aloe dichotoma, the quiver tree or kokerboom, is a tall, branching species of succulent plant, indigenous to Southern Africa, specifically in the Northern Cape province of South Africa, and parts of Southern Namibia.
Gonialoe variegata, also known as tiger aloe and partridge-breasted aloe, is a species of flowering plant in the family Asphodelaceae. It is an evergreen succulent perennial indigenous to South Africa and Namibia. It is common in cultivation.
Gonialoe dinteri, the Namibian partridge aloe, is a species of flowering plant in the Asphodelaceae family. It is native to arid areas of Angola and Namibia.
Gonialoe sladeniana is a species of plant in the genus Gonialoe. It is endemic to arid areas of central Namibia.
Aloe maculata, the soap aloe or zebra aloe, is a Southern African species of aloe. Local people in South Africa know it informally as the Bontaalwyn in Afrikaans, or lekhala in the Sesotho language.
A xerophyte is a species of plant that has adaptations to survive in an environment with little liquid water. Examples of xerophytes include cacti, pineapple and some gymnosperm plants. The morphology and physiology of xerophytes are adapted to conserve water during dry periods. Some species called resurrection plants can survive long periods of extreme dryness or desiccation of their tissues, during which their metabolic activity may effectively shut down. Plants with such morphological and physiological adaptations are said to be xeromorphic. Xerophytes such as cacti are capable of withstanding extended periods of dry conditions as they have deep-spreading roots and capacity to store water. Their waxy, thorny leaves prevent loss of moisture.
AnacampserosL. is a genus comprising about a hundred species of small perennial succulent plants native to Southern Africa, Ethiopia and Latin America. The botanical name Anacampseros is an ancient one for herbs supposed to restore lost love.
Portulacaria afra is a small-leaved succulent plant found in South Africa. These succulents commonly have a reddish stem and leaves that are green, but also a variegated cultivar is often seen in cultivation. They are simple to care for and make easy houseplants for a sunny location. In frost-free regions they may be used in outdoor landscaping.
Haworthia bayeri is a species of the genus Haworthia in the family Asphodelaceae, endemic to the southern Cape Provinces in South Africa.
Anacampseros lanceolata is a species of succulent plant native to the western Karoo and Overberg regions of South Africa.
Anacampseros arachnoides is a species of succulent plant native to the Little Karoo region of South Africa.
Anacampseros albidiflora is a species of succulent plant native to the Great Karoo and Little Karoo regions of South Africa.
Anacampseros retusa is a species of succulent plant native to the Northern Cape and Western Cape Provinces of South Africa, as well as to Namibia.
Anacampseros filamentosa is a species of succulent plant native to the Karoo region of South Africa.
Crassula atropurpurea is a succulent plant, very common and widespread in the southern Karoo regions of South Africa and Namibia.
Protea pendula, also known as the nodding sugarbush or arid sugarbush, is a flowering plant of the genus Protea, in the family Proteaceae, which is only found growing in the wild in the Cape Region of South Africa. In the Afrikaans language it is known as knikkopsuikerbossie or ondersteboknopprotea.
Selago eckloniana is a species of plant in the family Scrophulariaceae. It is endemic to the Western Cape, South Africa.
Anacampseros papyracea is a species of succulent plant in the family Anacampserotaceae. It is endemic to Southern Africa.
Myriopteris rawsonii, formerly known as Cheilanthes rawsonii, is a perennial fern native to Namaqualand in Southern Africa. Like many other cheilanthoid ferns, it is adapted to dry conditions, bearing a thick layer of pale hairs on the underside of its pinnate-pinnatifid leaves. It is the only African representative of its clade of cheilanthoids, the otherwise American genus Myriopteris. It spends much of the year in a dried-out, dormant state, rehydrating and putting out new growth during winter rains. Its name honors the botanist and civil servant Sir Rawson W. Rawson.
