General Information

Salix humboldtiana Willd., Sp. Pl. 4: 657. 1806.

Arboles o arbustos, 4–15 m de alto, corteza profundamente acanalada; ramas delgadas, flexuosas, puberulentas, con la corteza rojiza al secarse, ramitas jóvenes amarillentas al secarse; plantas dioicas. Hojas linear-lanceoladas, 4–15 cm de largo y 0.4–1 cm de ancho, ápice atenuado a agudo, base aguda a angostamente cuneada, márgenes serrulados, pilosas cuando jóvenes, glabras con la edad; pecíolos 3–7 mm de largo, acanalados en su parte adaxial, estípulas caducas. Inflorescencias 2–5.5 cm de largo, el raquis piloso o glabro; flores estaminadas con 3–5 (–7) estambres; flores pistiladas estipitadas, el estípite 1–1.5 mm de largo, ovario angostamente elipsoide. Fruto ovoide a elipsoide, ca 3 mm de largo, 2-valvado, glabro; semillas numerosas, ca 1 mm de largo.

Comúnmente cultivada, en bosques de galería, márgenes de ríos y bancos de arena, en todas las zonas del país; 0–950 m; fl y fr durante todo el año; Moreno 4892, Stevens 21419; México y Belice hasta Chile y Argentina. Un género con ca 300 especies, mayormente distribuidas en las regiones templadas del hemisferio norte. Según Schneider el nombre S. chilensis Molina es ambiguo y probablemente se aplique a una planta de otra familia. S. babylonica L., nativa de Eurasia, es cultivada en Nicaragua, sin embargo no ha sido recolectada; se puede distinguir de S. humboldtiana por sus flores estaminadas con 2 estambres por flor, sus flores pistiladas sésiles y sus hojas discoloras. Fue tratada como S. chilensis en la Flora of Guatemala. "Sauce llorón".
