Buddleja incana is a species of shrub or tree in the family Scrophulariaceae. It is native to the Andes.[1]
Buddleja incana is a dioecious tree or shrub, 4 - 15 m tall, the trunk < 50 cm at the base, the bark brownish and furrowed. The branches are subquadrangular and tomentose, and form a rounded crown. The coriaceous leaves are mostly oblong, 7 - 21 cm long by 1 - 5 cm wide, the upper surface glabrescent, often bullate or rugose, the lower white or yellowish tomentose. The yellow to orange paniculate inflorescences have 2 - 3 orders of leafy-bracted branches bearing heads 1 - 1.5 cm in diameter, each with 15 - 40 flowers, the corollas 3 - 4 mm long. Ploidy: 2n = 76.[1]
Buddleja incana is present in Bolivia, Peru, Ecuador and Colombia, growing in canyon bottoms along streams at elevations of 2,700 - 4,500 m.
Buddleja incana is called kiswar in Quechua,[2] [3] kiswara in Aymara,[4] quishuar in Spanish.[5]
The leaves are used in folk medicine against toothache and as diuretic.[1]
