Discussion:This subspecies is identical to subspecies glaucescens except for the thick corky bark which occurs from the young branches to the trunk. The interior of the receptacle is glabrous, not filled with hairs as in subsp paraensis whose geographical range comes closer to that of subsp cerradoana than to subsp glaucescens. Subspecies cerradoana grows on the northermost limits of the cerrado whilst the other subspecies are confined to the Amazonian forest regions. This subspecies and C. grandiflora are the only species of Couepia with a thick, corky bark. Subspecies cerradoana differs from C. grandiflora in the smaller flowers with glabrous petals (except for the ciliate margins), and in the sparsely puberulous exterior of the receptacle.
