Picconia (''Picconia'') is a genus of two species flowering plants in the family Oleaceae. In the laurel forests habitat, of Macaronesia islands of the eastern North Atlantic.〔http://biblioteca.universia.net/html_bura/ficha/params/title/vegetative-propagation-of-the-endangered-azorean-tree-picconia-azorica/id/54598910.html〕 They are evergreen shrubs to trees with large, opposite, entire, shiny, ovoid leaves and numerous flowers. The fruit is a drupe. The flowers are small white and fragrant, followed by one-seeded, olive-like green fruit, ripening to bluish-black.〔http://www.rareplants.de/shop/prodtype.asp?strPageHistory=compare&CAT_ID=714〕 Picconia are native of open spots in the laurel forest of the Canary Islands and Madeira where they are found only in the humid to hyper-humid evergreen forests of the cloud belt.〔http://ec.europa.eu/environment/nature/natura2000/management/habitats/pdf/9360_Macaronesian_laurel_forests.pdf〕 Tree species with laurel-shaped leaves are predominant, forming a dense canopy up to 40 m high that can be hardly trespassed by light, which results in scant vegetation in the understory.〔http://ec.europa.eu/environment/nature/natura2000/management/habitats/pdf/9360_Macaronesian_laurel_forests.pdf〕 Most of these tree species in Africa are ancient Paleoendemic〔http://rspb.royalsocietypublishing.org/content/273/1598/2149.full〕 species of the genera Laurus, Ocotea, Persea, and Picconia, which in ancient times were widely distributed on the African and European continents.〔http://ec.europa.eu/environment/nature/natura2000/management/habitats/pdf/9360_Macaronesian_laurel_forests.pdf〕〔http://rspb.royalsocietypublishing.org/content/273/1598/2149.full〕 ==Species== *''Picconia azorica'' - endemic to the archipelago of the Azores〔Secretaria Regional do Ambiente e do Mar (2008), ''Plantas Endémicas dos Açores: Guia da Ilha do Faial'', p.13〕 *''Picconia excelsa'' - tree up to 15m; Madeira, Canaries 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Picconia」の詳細全文を読む スポンサード リンク
