Buddleja corrugata is a species endemic to north-western Mexico including the Baja California Sur, growing on limestone at altitudes of 200 - 1900 m; it was first described and named by Jones in 1933.[1] [2]
Buddleja corrugata is a small, dioecious, multi-branched shrub 0.1 - 1 m high, with grey-black rimose bark. The young branches are terete and tomentose, bearing small, sessile, subcoriaceous ovate, ovate-oblong, or linear, leaves 1 - 4 cm long by 0.2 - 3 cm wide. The yellow or orange inflorescences comprise 3 - 8 pairs of globose heads 0.5 - 1 cm in diameter, each with 6 - 20 flowers, subtended by short bracts; the corolla tubes are 2 - 4 mm long.[2]
The species is considered closely related to Buddleja utahensis and Buddleja marrubiifolia.[2]
Jones identified three subspecies, distinguished by differences in the leaves:
The species is not known to be in cultivation.
