''Salix taxifolia'' (yewleaf or yew-leaf willow) is a species of willow native to all of southern Mexico, also Pacific Coast regions, north to Sinaloa, and in the south Pacific Coast of Mexico into central Guatemala. Scattered populations are also reported from northern Mexico and from the US states of Texas, New Mexico, and Arizona.〔Elbert L. Little (1976), ''Atlas of United States Trees, Volume 3, Minor Western Hardwoods'', US Government Printing Office. Library of Congress No. 79-653298, Map 183-SW, Map 183-N, ''Salix taxifolia''.〕〔(Flora of North America, vol 7 p 54 ).〕〔Laferrière, Joseph E. 1994. Vegetation and flora of the Mountain Pima village of Nabogame, Chihuahua, Mexico. Phytologia 77:102-140.〕 It is a large shrub or tree with narrow linear leaves similar to those of a yew (Taxus spp.), thus its common name. Its range is similar to that of the Bonpland willow, ''S. bonplandiana''. ==Distribution== The primary range of yewleaf willow is southern Mexico south of the Trans-Mexican Volcanic Belt and the Pacific coast region, then into Pacific coast–central Guatemala.〔 Besides the core range area, (of the northern Sierra Madre Occidentals) in Arizona–New Mexico and northeast Sonora,〔 two larger disjunct regions occur in west Texas and central Chihuahua.〔 South of Chihuahua, Chihuahua it is found at the Conchos River, and west of the city, a large area at the lake region. It also occurs in scattered, isolated locales of Durango, Sinaloa, and in the northeast at Nuevo Leon and Tamaulipas: also extreme southern Baja California Sur, (west of Sinaloa-Durango across the Gulf of California).〔 Besides parts of the Sierra Madre Occidental, locales occur in the southern Sierra Madre Oriental cordillera, but also small isolated locales as far northeast as the northeast states. Its range is similar to that of the Bonpland willow, ''Salix bonplandiana'', except ''S. bonplandiana'' covers almost the entire north-south extent of the Sierra Madre Occidentals; yewleaf is more intermittent in that range. 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「Salix taxifolia」の詳細全文を読む スポンサード リンク
