An examination of the type collection of Psychotria necopinata proves it to be conspecific with P. pacimonica. Although the inflorescence of P. necopinata is in a poor state of preservation, the calyx margin shows the subtruncate character of P. pacimonica. Other basic features in common are the corniculate appendaged corolla lobes, the profusion of yellowish brown mats of pubescence between the bases of the flowers, glabrous interior of the corolla tube, and eight bracts of varying length subtending the inflorescence. In the type collection of P. necopinata, six bracts are to be seen in their entirety, while two others are broken off above their bases. The 3-parted or tricephalous inflorescence of P. necopinata departs somewhat in character from the generally more or less monocephalous type shown in P. pacimonica, as variation in other monocephalous types of inflorescence, as aging of the inflorescence develops, occurs in P. lourteigiana, P. barbiflora, P. hoffmannseggiana, and others.
