Citrullus Ecirrhosus
''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 (''Citrullus lanatus''). It can be found in both Namibia and 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. The vines can crawl for up to two meters, and it has yellow flowers. As a desert plant, it is a hardy species, surviving with little water and strong sunlight. The leaves form annual stems which die back each year. The plant relies on water deep in the ground and morning fogs. It is an important source of water for numerous desert fauna. The bitter-tasting fruit it produces are known as tsamma melons. Experiments done by Simmons, Jarret, Cantrell, and Amnon in 2019 introduced the hybridization of ''Citrullus ecirrhosus'' and ''Citrullus lanatus'' developed a cultivated watermelon c ...

Citrullus Amarus
The citron melon (''Citrullus caffer''), also called ''Citrullus lanatus'' var. ''citroides'' and ''Citrullus amarus'', fodder melon, preserving melon, red-seeded citron, jam melon, stock melon, Kalahari melon or tsamma melon, is a relative of the watermelon. It is in 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 modern times; 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. History The citron melon is native to Africa, probably the Kalahari desert, where it still grows abundantly. The time and place of its first domestication is unknown, but it appears to have been grown in ancient Egypt at least four ...

Desert Fruits
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the ...

Flora Of South Africa
The wildlife of South Africa consists of the flora and fauna of this country in southern Africa. The country has a range of different habitat types and an ecologically rich and diverse wildlife, vascular plants being particularly abundant, many of them endemic to the country. There are few forested areas, much savanna grassland, semi-arid Karoo vegetation and the fynbos of the Cape Floristic Region. Famed for its national parks and big game, 297 species of mammal have been recorded in South Africa, as well as 849 species of bird and over 20,000 species of vascular plants. Geography South Africa is located in subtropical southern Africa, lying between 22°S and 35°S. It is bordered by Namibia, Botswana and Zimbabwe to the north, by Mozambique and Eswatini (Swaziland) to the northeast, by the Indian Ocean to the east and south, and the Atlantic Ocean to the west, the coastline extending for more than .

Flora Of Namibia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ...

Melons
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 botanical berry, berry, specifically a "pepo (botany), pepo". The word ''melon'' derives from Latin ', which is the Latinisation (literature), latinization of the Ancient Greek, Greek (''mēlopepōn''), meaning "melon",. itself a compound of (''mēlon''), "apple, treefruit (''of any kind'')" and (''pepōn''), amongst others "a kind of gourd or melon". Many different cultivars have been produced, particularly of cantaloupes. History Melons originated in Africa or in the hot valleys of Southwest Asia, especially Iran and India, from where they gradually began to appear in Europe toward the end of the Western Roman Empire. Melons are known to have been grown by the ancient Egyptians. However, recent discoveries of melon seeds dated between 1350 and 1120 BCE in Nuragic sa ...

Cucurbitoideae
The Cucurbitoideae are a subfamily of the flowering plant family Cucurbitaceae (gourds). The Cucurbitaceae are divided into two subfamilies, the Zanonioideae, probably a paraphyletic group of remainders, and the well-supported monophyletic Cucurbitoideae. The subfamily Cucurbitoideae consists of eight tribes. Members of the tribe Cucurbiteae produce economically valuable fruits, called gourds, which include crops like squashes (including pumpkins), luffas, and melons (including watermelons). The tribe Benincaseae contains a genus called ''Lagenaria ''Lagenaria'' is a genus of gourd-bearing vines in the squash family (Cucurbitaceae). ''Lagenaria'' contains six species, all of which are indigenous to tropical Africa.

Namib Desert
The Namib ( ; pt, Namibe) is a coastal desert in Southern Africa. The name is of Khoekhoegowab origin and means "vast place". According to the broadest definition, the Namib stretches for more than along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River (Western Cape), Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends 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 inland to the foot of the Great Escarpment, Southern Africa, Great Escarpment. Annual precipitation ranges from in the most arid regions to at the escarpment, making the Namib the only true desert in southern Africa. Having endured Desert climate, arid or Semi-arid climate, semi-arid cond ...

Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ...
