Antidesma Venosum
''Antidesma venosum'', commonly known as the tassel-berry, is a species of small dioecious tree in the family Phyllanthaceae. It is native to Africa, China and Indochina Mainland Southeast Asia, also known as the Indochinese Peninsula or Indochina, is the continental portion of Southeast Asia. It lies east of the Indian subcontinent and south of Mainland China and is bordered by the Indian Ocean to the west an .... Numerous small, sessile flowers are produced on drooping catkin-like spikes, which are about 10 cm long. The flowers produce an unpleasant smell, and the tree is in fruit for more than a month during late summer. Each small, oval-shaped fruit measures about 8 x 4 mm in size. They are initially fleshy green, and change to bright red and eventually purplish black as they ripen. The fruit are utilized by many species of animal and bird.

Dioecious
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phyllanthaceae
Phyllanthaceae is a family of flowering plants in the eudicot order Malpighiales. It is most closely related to the family Picrodendraceae.Kenneth J. Wurdack and Charles C. Davis. 2009.

(see ''External links'' below) The Phyllanthaceae are most numerous in the tropics, with many in the south temperate zone, and a few ranging as far north as the middle of the north temperate zone.Petra Hoffman. 2007.

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, Scramble for Africa, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indochina
Mainland Southeast Asia, also known as the Indochinese Peninsula or Indochina, is the continental portion of Southeast Asia. It lies east of the Indian subcontinent and south of Mainland China and is bordered by the Indian Ocean to the west and the Pacific Ocean to the east. It includes the countries of Cambodia, Laos, Myanmar, Thailand and Vietnam, with peninsular Malaysia sometimes also being included. The term Indochina (originally Indo-China) was coined in the early nineteenth century, emphasizing the historical cultural influence of culture of India, Indian and Chinese culture, Chinese civilizations on the area. The term was later adopted as the name of the colony of French Indochina (today's Cambodia, Laos, and Vietnam). Today, the term, Mainland Southeast Asia, in contrast to Maritime Southeast Asia, is more commonly referenced. Terminology The origins of the name Indo-China are usually attributed jointly to the Danish-French geographer Conrad Malte-Brun, who referred ...

Flora Of Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. 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 Thurm ...

Flora Of China
The flora of China consists of a diverse range of plant species including over 39,000 vascular plants, 27,000 species of fungi and 3000 species of bryophytes.Wu, Z. Y., P. H. Raven & D. Y. Hong, eds. 2006. Flora of China. Vol. 22 (Poaceae). Science Press, Beijing, and Missouri Botanical Garden Press, St. Louis More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China's land, extending over 9.6 million km, contains a variety of ecosystems and climates for plants to grow in. Some of the main climates include shores, tropical and subtropical forests, deserts, elevated plateaus and mountains. The events of the continental drift and early Paleozoic Caledonian movement also play a part in creating climatic and geographical diversity resulting in high levels of endemic vascular flora. These landscapes provide different ecosystems and climates for plants to grow in, cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antidesma
''Antidesma'' is a genus of tropical plant in the family Phyllanthaceae formally described by Linnaeus in 1753. It is native to tropical Africa, S + E + SE Asia, Australia, and various oceanic islands. The greatest diversity occurs in Southeast Asia. Description ''Antidesma'' is a variable genus which may be short and shrubby or tall and erect, approaching 30 metres in height. It has large oval shaped leathery evergreen leaves up to about 20 centimetres long and seven wide. The flowers have a strong, somewhat unpleasant scent. The staminate flowers are arranged in small bunches and the pistillate flowers grow on long racemes which will become the long strands of fruit. The fruits are spherical and just under a centimeter wide, hanging singly or paired in long, heavy bunches. They are white when immature and gradually turn red, then black. When they are still white they have sour and astringent taste, sour taste when they are red and have sweet and sour taste when they are bl ...
