''Juglans jamaicensis'' (West Indian walnut, ''nogal'', ''palo de nuez'') is a species of walnut in the Juglandaceae family. It is found in Cuba, the Dominican Republic, Haiti, and Puerto Rico. It is not, in fact, native to Jamaica, as its name would suggest.〔World Conservation Monitoring Centre 1998. (''Juglans jamaicensis'' ). (2010 IUCN Red List of Threatened Species. ) Downloaded on 20 April 2011.〕 This is a large tree which can reach 25 meters in height. The compound leaves are each made up of several lance-shaped, toothed leaflets up to 9 centimeters long. Trees bear male and female inflorescences, the male a catkin up to 11 centimeters long and the female an array of flowers at the end of a newly grown shoot. The fruit is a drupe roughly 2 to 3 centimeters long with a black husk and a seed, which is an edible walnut meat, inside.〔USFWS. (Determination of endangered status for ''Juglans jamaicensis''. ) ''Federal Register'' 13 January 1997.〕 In Puerto Rico there are only ten〔 to fourteen〔 trees of this species remaining. It is also rare in Cuba and Hispaniola.〔 It is threatened by habitat loss. It may never have been common, but specimens were likely lost when forest was cleared for coffee plantations on Puerto Rico, and it was probably harvested for wood.〔 The attractive wood is similar to that of the black walnut (''Juglans nigra'').〔Francis, J. K. and S. Alemany. (1994). (''Juglans jamaicensis'' C. DC. ) USDA Forest Service, International Institute of Tropical Forestry, New Orleans, LA, USA.〕 This tree has protection under the Endangered Species Act of the United States, where it is listed as an endangered species.〔 ==References== 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「Juglans jamaicensis」の詳細全文を読む スポンサード リンク
