Cypress is the name applied to many plants in the cypress family Cupressaceae, which is a conifer of northern temperate regions. Most cypress species are trees, while a few are shrubs. ''Cupressus sempervirens'' is famous for its longevity, and has been a popular garden plant for thousands of years. The word cypress is derived from Old French cipres, which was imported from Latin cypressus the latinisation of the Greek κυπάρισσος (''kyparissos'').〔(κυπάρισσος ), Henry George Liddell, Robert Scott, ''A Greek-English Lexicon'', on Perseus Digital Library〕〔http://www.etymonline.com/index.php?term=cypress〕 *African cypress (''Widdringtonia'' species) *Bald, pond, and Montezuma cypresses (''Taxodium'' species, native to North America) *Chinese swamp cypress (''Glyptostrobus pensilis'') *Cordilleran cypress (''Austrocedrus chilensis'') *Cypress (''Callitropsis'' species) *Cypress (''Cupressus'' species) *Cypress-pines (''Actinostrobus'' species) *Cypress-pines (''Callitris'' species) *False cypress (''Chamaecyparis'' species) *Fujian cypress (''Fokienia hodginsii'') *Guaitecas cypress (''Pilgerodendron uviferum'') *Patagonian cypress (''Fitzroya cupressoides'') *Siberian cypress (''Microbiota decussata'') The Cupressaceae family also contains 13–16 other genera (not listed above) that do not bear ''cypress'' in their common names. The word ''cypress'' is also used as a descriptor for the angiosperm vine in the bindweed family Convolvulaceae, known as the cypress vine (''Ipomoea quamoclit''). The plant called "summer cypress" is ''Bassia scoparia'' (Amaranthaceae). ==Allergenic potential== Highly allergenic species of cypress with an OPALS allergy scale rating of 8 or higher include: Taxodium, Cupressus, Callitris, Chamaecyparis, Asutrocedrus males, and Widdringtonia males and monoecious. Species of cypress with very low potential for causing allergies (an OPALS allergy scale rating of 2 or lower) include: Austrocedrus females and Widdringtonia females. 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「cypress」の詳細全文を読む スポンサード リンク
