Buddleja sphaerocalyx is a species endemic to Madagascar, where it grows in moist forests, principally along river banks, at altitudes of 300 - 2,200 m. [1]. The species was named and described in 1887 by Baker.[2]
B. sphaerocalyx is a sarmentose shrub 2 - 3 m in height, the branchlets obscurely quadrangular, bearing opposite, connate-perfoliate leaves, 10- 21 cm long by 3.0 - 11 cm wide, narrowly ovate, acuminate at the apex, and narrowing abruptly at the base; the margins irregularly crenate - dentate. The white inflorescences comprise solitary axillary flowers 4 - 10 cm long by 1.5 - 6 cm wide; the corollas 8.5 - 20 mm long.
B. sphaerocalyx is closely allied to B. axillaris and B. cuspidata. [1]
B. sphaerocalyx is not known to be in cultivation. [1]
