Buddleja cuspidata is a species endemic to Madagascar, where it grows along river banks. The species was first named and described by Baker in 1895.[1]
Buddleja cuspidata is a shrub 3–4 m in height, with brown tomentose branchlets, obscurely quadrangular. The opposite, thinly - coriaceous leaves blades are ovate or elliptic, 9–20 cm long by 4–9 cm wide, acuminate at the apex, decurrent into the petiole, sparsely pubescent above, brown tomentose beneath; the margins serrate - dentate to crenate - dentate. The narrow yellow inflorescences are axillary and spicate, 3–15 cm long by 1–1.5 cm wide; the corollas 7.5–8.5 mm long.
Buddleja cuspidata is considered closely allied to B. axillaris and B. sphaerocalyx.[2]
Buddleja cuspidata is not known to be in cultivation.
