''Buddleja coriacea'' is a variable species endemic to the high Andes from the Cordillera Blanca in Peru to Lake Titicaca in Bolivia. It grows on dry to semi-humid rocky soils at elevations of 3,000–4,350 m,〔Norman, E. M. (2000). Buddlejaceae. ''Flora Neotropica 81''. New York Botanical Garden, USA〕 where temperatures range from -3° to 15° C. and the winds are both strong and persistent.〔Jøker, D., Cruz, N., Morales, M., & Rojas, E. (2002).

''Algunas Especies Forestales nativas Para la Zona Altoandina.'' (''Some native forest species for the High Andes''). CONDESAN (Consorcio para el Desarrollo Sostenible de la Ecorregion Andina), Lima, Peru.〕() The species was first named and described by Rémy in 1847.〔 ==Description== ''B. coriacea'' typically makes a densely crowned, sprawling trioecious shrub or tree, branching almost at ground level. Usually growing to less than 4 m in height in the wild, it can occasionally reach 12 m, with stems up to 40 cm in diameter; the bark is fissured.〔〔 The species is chiefly distinguished by its small, thick, leathery leaves, 1–4 cm long by 0.5–1.5 cm wide, with 3–4 mm petioles. The upper surfaces of the leaves are dark-green and glabrous, contrasting with the undersides which are covered in a cinnamon-brown indumentum. The scented inflorescences comprise 3–8 pairs of head-like cymes, 0.9–1.2 cm in diameter, of 8–12 flowers, the corollas 4.5–6 mm in length, deep yellow to orange-yellow, becoming orange-red with age. Flowering occurs throughout the year, but most commonly between December and June. Ploidy: ''2n'' = 76 (tetraploid). 〔
