Buddleja jamesonii is a species endemic to southern Ecuador, where it grows in moist, protected ravines and borders of tussocks at elevations of 3,000 – 4,000m. The species, first named and described by Bentham in 1846, is now threatened by habitat loss. The specific name commemorates the Scottish botanist William Jameson (1796–1873) who collected in Ecuador.

The corolla is 3.5 – 4.5mm long.
