Apocynaceae
Apocynaceae (from ''Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here. Many species are tall trees found in tropical forests, but some grow in tropical dry (xeric) environments. Also perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter often finding use as arrow poisons. Some genera of Apocynaceae, such as '' Adenium'', bleed clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caralluma
''Caralluma'' is a genus of flowering plants in the family Apocynaceae, consisting of about 120 species. In 1795 William Roxburgh published the name '' Stapelia adscendens'' for a plant found in India. He commented that the name for the plant in the Telugu language was ''Car-allum'' and that the succulent branches are edible raw, though bitter and salty. The name ''Caralluma'' was coined by Robert Brown for a new genus in an article published in 1811. At the time he only described one species in the genus, the plant that he renamed '' Caralluma adscendens''. In 1996 Helmut Genaust published the suggestion that it was sensible to conclude that the generic name is derived from the Arabic phrase ''qahr al-luhum'', meaning "wound in the flesh" or "abscess," referring to the floral odour. Genaust was unaware that the genus ''Caralluma'' existed east of Palestine. He specifically ruled out its existence in India, where it was first described and named. Genaust presumed that the na ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
