Camptocarpus acuminatus is a species of plant in the Apocynaceae family. It is endemic to the Madagascar.[4] Pierre Choux,[5] the botanist who first formally described the species, named it after the tapering (acuminatus in Latin) tips of its leaves, using the synonymous name Tanulepis acuminata.[6][7]

Description

It is a woody climbing plant. The oval to disc-shaped leaves are 27–41 by 13–19 millimeters. Its leaves taper to a distinctive tip. Its petioles are 3–5 millimeters long. It has small flowers that are 2.4–2.5 millimeters long. Its 5 petals are fused at the base forming a tube. The flowers have a structure between the petals and the stamen called a corona. The base of the corona forms a ring that is fused with the base of the petals and the stamen. Its corona has 5 thread-like lobes that are radially aligned with the stamen. Its flowers have 5 stamen.[7]

Reproductive biology

The pollen of Camptocarpus acuminatus is shed as permanent tetrads.[8]

Distribution and habitat

It has been observed growing in humid forests at elevations of 600 to 1200 meters.[2]
