[2] William Burck, the Dutch botanist who first formally described the species using the synonym Meiogyne macrocarpa, named it after its large fruit (Latinized forms of Greek μακρoς, macros and καρπoς, karpos).
The young, gray to dark brown branches are sparsely hairy, but become hairless when mature.
Its sparsely to densely hairy petioles are 6-15 by 1.5-3.5 millimeters with a broad groove on their upper side.
Its Inflorescences occur in clusters of 5–8 on branches, and are organized on indistinct peduncles.
The inner petals have a solitary, butterfly-shaped, smooth, raised gland on their upper surfact.
Each fruit has 4-7 hemi-spherical to lens-shaped seeds that are 10–14.5 by 7-10 by 4-8 millimeters and are arranged in two rows.
[6] It has been observed growing in low-nutrient and clay soils in lowland or submontane forests at elevations of 30–2400 meters.
