range of the genus |
Delosperma ('delos'=evident, 'sperma'=seed) is a genus of around 170 species of succulent plants, formerly included in Mesembryanthemum in the family Aizoaceae. It was defined by English botanist N. E. Brown in 1925. [1] The genus is common in southern and eastern Africa, with a few species in Madagascar, Reunion island, Yemen and Saudi Arabia. [2] [3] Delosperma species, as do most Aizoaceae, have hygrochastic capsules, opening and closing as they wet and dry. [4]
Plants of the genus Delosperma can be distinguished by their seed capsules. When these open (in response to rain), the seeds are exposed and not covered by a protective membrane, like those of most other plants in the family. The membrane is sometimes reduced to just a ledge (a feature shared by the related genus Trichodiadema . The triangular valves, which open outwards when wet, each have distinctive wings on either side.
Delosperma leaves tend to grooved or covered in bladder cells, which are sometimes even extended into hairs. The leaf shape is cylindrical or sometimes flattened. [5]
Delosperma species are long-lived, and flower mostly in the summer. Their flowers vary greatly in colour.
Species include:
The Aizoaceae, or fig-marigold family, is a large family of dicotyledonous flowering plants containing 135 genera and about 1800 species. They are commonly known as ice plants or carpet weeds. They are often called vygies in South Africa and New Zealand. Highly succulent species that resemble stones are sometimes called mesembs.
Lithops is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words λίθος 'stone' and ὄψ 'face', referring to the stone-like appearance of the plants. They avoid being eaten by blending in with surrounding rocks and are often known as pebble plants or living stones. Lithops is both the genus name and the common name. The formation of the name from the Ancient Greek -ops means that even a single plant is called a Lithops.
Lampranthus is a genus of succulent plants in the family Aizoaceae, indigenous to southern Africa.
Delosperma echinatum is a succulent plant, native to South Africa. It is also known as the pickle plant. The new genus Delosperma was erected by English botanist N. E. Brown in 1925, with this species later acknowledged as the type species.
Ruschia is a genus of succulent plant, in the family Aizoaceae, indigenous to the dryer parts of southern Africa.
Mesembryanthemum crystallinum is a prostrate succulent plant native to Africa, Sinai and southern Europe, and naturalized in the New World. The plant is covered with large, glistening bladder cells or water vesicles, reflected in its common names of common ice plant, crystalline ice plant or ice plant.
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.
Glottiphyllum longum is a species of succulent plant in the family Aizoaceae, native to the Western Cape and Eastern Cape Provinces, South Africa.
Cleretum bellidiforme, commonly called Livingstone daisy, Bokbaaivygie (Afrikaans), or Buck Bay vygie, is a species of flowering plant in the family Aizoaceae, native to the Cape Peninsula in South Africa. It is a low-growing succulent annual growing to 25 cm (10 in), and cultivated for its iridescent, many-petalled, daisy-like blooms in shades of white, yellow, orange, cream, pink and crimson. In temperate areas it is popularly grown as a half-hardy annual, and lends itself to mass plantings or as edging plants in summer bedding schemes in parks and gardens. It is still widely referenced under its former names, Mesembryanthemum criniflorum and Dorotheanthus bellidiformis.
Mitrophyllum is a genus of succulent plants of the family Aizoaceae, indigenous to the arid region around the Richtersveld, on the border of South Africa and Namibia.
Glottiphyllum depressum is a common species of succulent plant, of the family Aizoaceae, native to South Africa.
Glottiphyllum fergusoniae is a species of succulent plant, of the family Aizoaceae. It is indigenous to the western part of the Little Karoo, in the Western Cape, South Africa.
Hartmanthus is a genus of tropical, succulent flowering plants in the family Aizoaceae, native to the lower Orange River in ǁKaras, Namibia and Northern Cape, South Africa.
Trichodiadema marlothii is succulent plant of the genus Trichodiadema, native to the Western Cape Province, South Africa, where it is known from the Robertson and Swellendam areas.
Trichodiadema mirabile is succulent plant of the genus Trichodiadema, native to the Western Cape Province, South Africa, where it is known from the Laingsburg area and especially from south-facing slopes.
Trichodiadema burgeri is succulent plant of the genus Trichodiadema, native to the Western Cape Province, South Africa, where it is known from the Ladismith and Oudtshoorn regions, extending southwards towards Mossel Bay.
Trichodiadema hallii is succulent plant of the genus Trichodiadema, native to the Ladismith and Calitzdorp areas of the Western Cape Province, South Africa.
Drosanthemum lavisii is a succulent plant in the ice plant family, Aizoaceae, indigenous to the Overberg region of the Western Cape Province, South Africa.
Trichodiadema barbatum is succulent plant of the genus Trichodiadema, native to the Eastern Cape Province, South Africa.
Mesembryanthemum digitatum, or finger-and-thumb plant, is a stemless plant found in South Africa with a clump of 2-4 thick, waxy leaves per shoot that emerge from the ground which resemble human-like fingers.
