Salix bonplandiana
Encyclopedia
Salix bonplandiana (Span.: Ahuejote, Sauce, Ahujote, Huejote), is a perennial species of willow
tree
native to southern and southwest Mexico
and extending into central Guatemala
; in western Mexico it is a tree of the Sierra Madre Occidental
cordillera, but also occurring in other small locales, for example Baja California Sur
, northern Sonora
, San Luis Potosi
, etc. A core disjunct
area occurs in central and southeast Arizona
, in advantageous locales, especially associated with higher elevations, and water.
. Across southern Mexico it is a species of the Trans-Mexican Volcanic Belt
, and has its range extension on the Pacific, west from the west of the Volcanic Belt, and then north into the Sierra Madre Occidental
cordillera. In the cordillera, the range ends in southwest Chihuahua, but is disjunct in a large area of central Arizona
, the Mogollon Rim
–White Mountains (Arizona)
and extending into the Madrean Sky Islands
southeastwards, including mountain-related isolated locales in the bootheel of extreme southwest
New Mexico
.
have identical ranges: both species range from the Trans-Mexican Volcanic Belt
southward, on an imaginary centerline into central Guatemala
. Each is on the Pacific Coast, but leave the coastal strip
before the range extension into central Guatemala. Both have their disjunct
ranges in Arizona, both being in the Madrean Sky Islands
region. Both also range into Baja California Sur
, but S. taxifolia only at the extreme south. (S. bonplandiana also occurs in Arizona, in the Mogollon Rim–White Mountains regions.)
The other differences between thw two: S. taxofolia occurs in minor locales of the Sierra Madre Oriental
cordillera, and S. bonplandiana occurs in the Sierra Madre Occidental cordillera northwest to southwest Durango
. S. taxifolia occurs west of the Occidental cordillera in the south Pacific Coast north to southern Sinaloa
–southwest Durango. B. bonplandiana has a few locales on the Mexican Plateau
, (with both occurring in central Chihuahua, west of Chihuahua, Chihuahua
). Other minor locale differences occur in central New Mexico
, far west Texas
, Coahuila
, Nuevo Leon
, and Tamaulipas
