Salix bonplandiana (Bonpland willow), (Spanish: ahuejote, sauce, ahujote, and huejote),[2] is a perennial species of willow tree native to southern and southwest Mexico and extending into central Guatemala;[3] 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.

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.

S. taxifolia occurs west of the Occidental cordillera in the south Pacific Coast north to southern Sinaloa–southwest Durango.

[4] Other minor locale differences occur in central New Mexico, far west Texas, Coahuila, Nuevo Leon, and Tamaulipas.
