[3] Julien Noël Costantin and Ernest-Isidore Gallaud, the botanists who first formally described the species, named it after its resemblance to, but distinctiveness from, plants in the genus Camptocarpus.

Its pendulous, branched Inflorescences occur in axillary and terminal positions and are 2-10 centimeters long.

Its flowers have 5 oblong to oval sepals that are 1.3–1.6 by 1.2–1.6 millimeters, with rounded tips and smooth margins.

Its 5 dull-red to purple petals are fused at the base forming a 1.8–2.7 millimeter long tube.

The connective tissue between the compartments forms and extended cap half again as long as the anther.

The hairless, long, thin, curved fruit are 20–28 by 0.2–0.3 centimeters that are recurved 45–90 degrees at their base.
