Citrullus rehmii De Winter | |
Citrullus rehmii, commonly known as the Namib melon, [1] is a species of annual melon in the family Cucurbitaceae [2] that is native to the Namib Desert, Namibia. [3] It was described by Bernard de Winter in 1990. [2] The species has a dark grey rind, with light brown-orange spots scattered throughout. It forms a vine with dark green leaves, and a light green stem. Flowers are a yellow color on the inside, and a white on the inside. They are non-edible, and are vastly different from other species of melon based on its general appearance. [1] The species is quite hard to find in its natural range, but has been spotted on more than one occasion. It is somewhat used as an ornamental plant, and overlaps with the Namib tsamma (Citrullus ecirrhosus) in Namibia. [3]
The Kalahari Desert is a large semi-arid sandy savanna in Southern Africa extending for 900,000 square kilometres (350,000 sq mi), covering much of Botswana, as well as parts of Namibia and South Africa.
At 824,292 km2 (318,261 sq mi), Namibia is the world's thirty-fourth largest country. After Mongolia, Namibia is the second least densely populated country in the world. Namibia got its name from the Namib desert that stretches along the coast of the Atlantic. It is also known for its wildlife.
Citrullus is a genus of seven species of desert vines, among which Citrullus lanatus is an important crop.
A melon is any of various plants of the family Cucurbitaceae with sweet, edible, and fleshy fruit. The word "melon" can refer to either the plant or specifically to the fruit. Botanically, a melon is a kind of berry, specifically a "pepo". The word melon derives from Latin melopepo, which is the latinization of the Greek μηλοπέπων (mēlopepōn), meaning "melon", itself a compound of μῆλον (mēlon), "apple", treefruit " and πέπων (pepōn), amongst others "a kind of gourd or melon". Many different cultivars have been produced, particularly of cantaloupes.
The Namib is a coastal desert in Southern Africa. According to the broadest definition, the Namib stretches for more than 2,000 kilometres (1,200 mi) along the Atlantic coasts of Angola, Namibia, and northwest South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends 450 kilometres (280 mi) from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to 200 kilometres (120 mi) inland to the foot of the Great Escarpment. Annual precipitation ranges from 2 millimetres (0.079 in) in the aridest regions to 200 millimetres (7.9 in) at the escarpment, making the Namib the only true desert in southern Africa. Having endured arid or semi-arid conditions for roughly 55–80 million years, the Namib may be the oldest desert in the world and contains some of the world's driest regions, with only western South America's Atacama Desert to challenge it for age and aridity benchmarks.
Citrullus colocynthis, with many common names including Abu Jahl's melon, colocynth, bitter apple, bitter cucumber, egusi, vine of Sodom, or wild gourd, is a poisonous desert viny plant native to the Mediterranean Basin and West Asia, especially the Levant, Turkey, and Nubia.
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.
Cucurbita moschata is a species originating in either Central America or northern South America. It includes cultivars known as squash or pumpkin. C. moschata cultivars are generally more tolerant of hot, humid weather than cultivars of C. maxima or C. pepo. They also generally display a greater resistance to disease and insects, especially to the squash vine borer. Commercially made pumpkin pie mix is most often made from varieties of C. moschata. The ancestral species of the genus Cucurbita were present in the Americas before the arrival of humans. No species within the genus is fully genetically isolated from all the other species. C. moschata can be hybridized with all other species. It has been suggested that this shows that the species of Cucurbita have diversified more recently than those of related genera such as Cucumis and Citrullus.
Cucumis myriocarpus, the gooseberry cucumber, gooseberry gourd, paddy melon, Mallee Pear or prickly paddy melon, is a prostrate or climbing annual herb native to tropical and southern Africa. It has small, round, yellow-green or green-striped fruit with soft spines, small yellow flowers and deeply lobed, light green leaves. The melon occurs in disturbed soil and cleared or bare areas, and thrives on summer moisture.
The citron melon, also called fodder melon, preserving melon, red-seeded citron, jam melon, stock melon, Kalahari melon or tsamma melon, is a relative of the watermelon. It is from the family Cucurbitaceae which consists of various squashes, melons, and gourds. Native to arid landscapes of sub-Saharan Africa, it has been a wild source of nutrition and hydration for humans for an extraordinarily long time. Its fruit has a hard white flesh, rendering it less likely to be eaten raw in the modern era; more often it is pickled or used to make fruit preserves, and is used for cattle feed. It is especially useful for fruit preserves, because it has a high pectin content.
Acanthosicyos horridus is an unusual melon that is endemic to the Namib desert. In English it is known as Nara, butter-nuts, or butterpips; in one of the Khoisan languages it is locally called ǃnaras or ǃnara.
Citrullus ecirrhosus, commonly known as Namib tsamma, is a species of perennial desert vine in the gourd family, Cucurbitaceae, and a relative of the widely consumed watermelon. It can be found in both Namibia and the Cape Provinces of South Africa, in particular the Namib Desert. It is the sister species to the bitter melon, Citrullus amarus with which it shares hard, white and bitter flesh.
Pentatrichia rehmii subsp. avasmontana is a subspecies of flowering plant in the family Asteraceae. It is found only in Namibia. Its natural habitat is rocky areas.
Pentatrichia is a genus of African plants in the tribe Gnaphalieae within the family Asteraceae.
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.
The Tsau ǁKhaeb (Sperrgebiet) National Park, formerly known as Sperrgebiet, is a diamond mining area in southwestern Namibia, in the Namib Desert. It spans the Atlantic Ocean-facing coast from Oranjemund on the border with South Africa, to around 72 kilometres (45 mi) north of Lüderitz, a distance of 320 km (200 mi) north. It extends to around 100 km (62 mi) inland, and its total area of 26,000 km2 (10,000 sq mi), makes up three percent of Namibia's land mass. However, mining only takes place in five percent of the Sperrgebiet, with most of the area acting as a buffer zone. Members of the public are banned from entering most of the area, despite the creation of a national park there in 2004.
Watermelon is a flowering plant species of the Cucurbitaceae family and the name of its edible fruit. A scrambling and trailing vine-like plant, it is a highly cultivated fruit worldwide, with more than 1,000 varieties.
Parkinsonia africana, the green-hair tree, is a species of flowering plant in the family Fabaceae, native to southern Angola, Botswana, and Namibia, and the Cape Provinces and Northern Provinces of South Africa. It is a bush growing 1–3m tall with green bark that allows for photosynthesis when the leaves are shed. It produces yellow flowers and yellow to brown pods. The wood does not crack when hot and is used to make smoking pipes.
Stipagrostis ciliata, the tall bushman grass, is a species of grass in the family Poaceae. The native range is from the Canary Islands, the Sahara desert to Pakistan. It occurs in Namibia's Namib Desert and the Kalahari. The grass grows 30–100 centimetres (12–39 in) tall and can be annual or perennial dependent on the amount of rainfall. It can be distinguished by a ring of long white hair surrounding each node.
Kalahari melon oil also known as Tsamma (Damara/Nama), wild watermelon (English), bitterboela, karkoer (Afrikaans), wild watermelon, makatane (Setswana) or Mokaté oil, is a plant oil, extracted from the seeds of the Kalahari melon (Citrullus vulgaris), which is endemic to the Kalahari Desert, spanning Namibia, Botswana and South Africa. Being one of 1,200 varieties of melon, Kalahari melon oil is distinct from regular watermelon seed oil. The seed of the Kalahari melon consists of approximately 50% oil, 35% protein and 5% dietary fibre.
