''Ekebergia'' is a genus of flowering plants belonging to the family Meliaceae. They are dioecious trees or shrubs, with odd-pinnate leaves. Its native range is tropical and southern Africa. Its genus name of ''Ekebergia'' is in honour of Carl Gustaf Ekeberg (1716–1784), Swedish physician, chemist and explorer. It was published and described in Kongl. Vetensk. Acad. Handl.

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meliaceae
Meliaceae, the mahogany family, is a flowering plant family of mostly trees and shrubs (and a few herbaceous plants, mangroves) in the order Sapindales. They are characterised by alternate, usually pinnate leaves without stipules, and by syncarpous, apparently bisexual (but actually mostly cryptically unisexual) flowers borne in panicles, cymes, spikes, or clusters. Most species are evergreen, but some are deciduous, either in the dry season or in winter. The family includes about 53 genera and about 600 known species, with a pantropical distribution; one genus (''Toona'') extends north into temperate China and south into southeast Australia, another (''Synoum'') into southeast Australia, and another (''Melia'') nearly as far north. They most commonly grow as understory trees in rainforests, but are also found in mangroves and arid regions. The fossil record of the family extends back into the Late Cretaceous. Uses Various species are used for vegetable oil, soap-making, ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 dioecious (gon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Gustaf Ekeberg
Carl Gustaf Ekeberg (10 June 1716 – 4 April 1784) was a Swedish physician, chemist and explorer. He made several voyages to the East Indies and China as a sea captain. He brought back reports of the tea tree and wrote a number of books. Biography Ekeberg was born at Djursholm in Uppland, Sweden. He was the son of Gustaf Ekeberg and Catharina Ebba Fast. He was a student at Uppsala University for three years (1726–1729); pharmacy student at Västerås (1730–1736); provisor in the pharmacy at Turku (1737–1738). Trained as a pharmacist and chemist, Ekeberg started his career as a ship's doctor, and became an expert navigator. Between 1742 and 1778 he made ten trips to India and China, becoming a captain in 1750 for the Swedish East India Company. He brought back numerous natural history specimens from his voyages for Carl Linnaeus, with whom he had a close friendship, and was honoured by having the genus ''Ekebergia'' created. Swedish ships from 1750 avoided calling at Cap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Described In 1779
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability t ...
