[1] Friedrich Anton Wilhelm Miquel, the Dutch botanist who first formally described the species using the basionym Orophea macrocarpa, named it after its large fruit (Latinized forms of Greek μακρoς, macros and καρπoς, karpos).

The upper side of the leaves are glossy and hairless, while the undersides are covered in sparse, fine hairs.

The 3 or more flowers occur on woody rachises positioned opposite leaves.

Flowers are attached to the rachis by fleshy, densely hairy pedicels that are 5–12.5 by 0.6-1 millimeters.

The outer petals are initially pale chartreuse with orange lines, turning pinkish at maturity.

Its fruit occur in clusters of up to 8–12 on woody pedicels that are 25 by 4.5-6 millimeters and covered in sparse, fine hairs.
