• Discussion

  This species is related to Coussarea longiflora Mull.-Arg. and C. brevicaulis Krause. It differs from C. longiflora in the absence of elongate calyx-lobes and nearly edentulate subtruncate calyx margin, from C. brevicaulis and C. longiflora in the longer corolla-lobes, from C. brevicaulis in the longer and broader calyx and hypanthium, and from all these in the longer pedicels, anthers, and corolla-lobes longer than the corolla-tube.
