Acanthosicyos Horridus
''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 or ("!" is pronounced with a click, somewhat like the "tsk" when English people are tutting, tsk-tsk). Description It is a dioecious, leafless, phreatophyte (meaning its roots penetrate deep down to water near the water table) that is found in sandy deserts but not stony plains, in areas with access to ground water such as ephemeral rivers and paleochannels, where sand accumulating in the shelter of its stems can form hummocks up to 1000–1500 m2 in area and 4 meters in height. Its stems may rise more than a meter above the hummocks, while its system of thick taproots can extend up to 50 m downward. The plant is leafless, so modified stems and spines 2–3 centimetres long serve as the photosynthetic "organs" of the plant. The plant can survive many years without water. Ecology ...

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 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 ... (including watermelons). The tribe Benincaseae contains a genus called '' Lagenaria'' whose members produce gourds that can be eaten when young or whose ripe shells can be dried and used as containers.

Hummock
In geology, a hummock is a small knoll or mound above ground.Bates, Robert L. and Julia A. Jackson, ed. (1984). “hummock.” Dictionary of Geological Terms, 3rd Ed. New York: Anchor Books. p. 241. They are typically less than in height and tend to appear in groups or fields. Large landslide avalanches that typically occur in volcanic areas are responsible for formation of hummocks. From the initiation of the landslide to the final formation, hummocks can be characterized by their evolution, spatial distribution, and internal structure. As the movement of landslide begins, the extension faulting results in formation of hummocks with smaller ones at the front of the landslide and larger ones in the back. The size of the hummocks is dependent on their position in the initial mass. As this mass spreads, the hummocks further modify to break up or merger to form larger structures. It is difficult to make generalizations about hummocks because of the diversity in their morphology a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A nabkha, nebkha or nebka is a type of sand dune. Other terms used include coppice dune and dune hummock or hummocky dune, but these more accurately refer to similar, but different, sand dune types.Langford, R. P.

Nama People
Nama (in older sources also called Namaqua) are an African ethnic group of South Africa, Namibia and Botswana. They traditionally speak the Nama language of the Khoe-Kwadi language family, although many Nama also speak Afrikaans. The Nama People (or Nama-Khoe people) are the largest group of the Khoikhoi people, most of whom have disappeared as a group, except for the Namas. Many of the Nama clans live in Central Namibia and the other smaller groups live in Namaqualand, which today straddles the Namibian border with South Africa. History For thousands of years, the Khoisan peoples of South Africa and southern Namibia maintained a nomadic life, the Khoikhoi as pastoralists and the San people as hunter-gatherers. The Nama are a Khoikhoi group. The Nama originally lived around the Orange River in southern Namibia and northern South Africa. The early colonialists referred to them as Hottentots. Their alternative historical name, "Namaqua", stems from the addition of the Kho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthosicyos Horridus Fruit In Namibia
''Acanthosicyos'' is a genus of thorny shrubs of the botanical family Cucurbitaceae, subfamily Cucurbitoideae. The genus name derives from the Greek words "''akantha''" for thorn and "''sykios''" for cucumber or gourd. Species Endemic to the Namib Desert in Africa, this genus is represented by two known species including ''Acanthosicyos horridus ''Acanthosicyos horridus'' is an unusual melon that is endemic to the Namib desert.

Both species are dioecious. Both the Nara and the Gemsbok Cucumber are edible; however, eating unripe fruit is highly inadvisable due to the presence of chemicals which "burn" the throat and esophagus. The bushmen of the Kalahari eat the Gemsbok Cucumber after it has been roasted in a fire for a couple of hours. This ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tettigoniidae
Insects in the family Tettigoniidae are commonly called katydids (especially in North America), or bush crickets. They have previously been known as "long-horned grasshoppers". More than 8,000 species are known. Part of the suborder Ensifera, the Tettigoniidae are the only extant (living) family in the superfamily Tettigonioidea. They are primarily nocturnal in habit with strident mating calls. Many species exhibit mimicry and camouflage, commonly with shapes and colors similar to leaves. Etymology The family name Tettigoniidae is derived from the genus '' Tettigonia'', first described by Carl Linnaeus in 1758. In Latin ''tettigonia'' means a kind of small cicada, leafhopper; it is from the Greek τεττιγόνιον ''tettigonion'', the diminutive of the imitative ( onomatopoeic) τέττιξ, ''tettix'', cicada. All of these names such as ''tettix'' with repeated sounds are onomatopoeic, imitating the stridulation of these insects. The common name ''katydid'' is also ...
