Buddleja brachystachya is a small shrub endemic to the Yunnan, Szechuan and Kansu provinces of China, where it grows on open, rocky, often dry, places at altitudes of between 2,000 and 2,400 m. It was first described and named by Diels in 1912. [1]
B. brachystachya grows to between 0.3 and 0.9 m in height, with subquadrangular to subterete, densely stellate - tomentose branchlets. The small, opposite leaves have elliptic blades, 1 - 3.5 cm long by 0.5 - 1.7 cm wide, acute or obtuse at the apex, cuneate or decurrent at the base, the margins entire. The lavender inflorescences are small, thyrsoid, and often few flowered, 1.5 - 3 cm long by 1.5 - 2.5 cm wide, the corollas 11 - 18 mm long. [2]
