The species was first named and described by Kunth in 1818.[1][2] DescriptionBuddleja perfoliata is a small dioecious shrub 0.8 – 2 m tall in the wild, much branched, and with a greyish-black shredding bark.

The yellow inflorescences, redolent of sage, are 5 – 25 cm long, comprising 5 – 26 pairs of heads borne in the axils of the leaves, each head about 1 cm in diameter with 30 – 40 flowers. Ploidy: 2n = 38.[2]CultivationThe species is not known to be in cultivation. References1. ^Kunth, in Humboldt, Bonpland, and Kunth. (1818).
