This African species is recognized in Paul Maas' monograph on African Costaceae, published on 16 December 2016. (Monograph of African Costaceae, H. Maas-van de Kamer, P.J.M. Maas, J.J. Wieringa, C.D. Specht, Blumea 61, 2016: 280 - 318,

Paul Maas has determined three species that he considers "epiphytic African species": Costus lateriflorus, Costus lilaceus, and Costus talbotii. He distinguishes the three from each other based upon the flower color and the shape and texture of the bracts. Costus talbotii he says "is distinct from the two other epiphytic African species of Costus by its much broader (to c. 2 cm wide) coriaceous bracts vs the chartaceous bracts (to 1.1 cm wide) in C. lateriflorus and C. lilaceus." Costus talbotii produces two flowers per bract with dark pink corolla lobes, and with a labellum that has pink dots in the throat with a yellow nectar guide.

Chelsea Specht studied the molecular phylogeny of this species and found it to be in a clade with Costus lateriflorus (Molecular Phylogenetics and Evolution 21:3, 333-345) which supports its grouping as an epiphytic Costus.

The African Plant Database lists this species as accepted. Epiphytic herb with ramose wiry stem covered with very long cylindrical ligules, reaching nearly to the next leaf.

Flora of West Tropical Africa, (1936) - remarkable for very long ligule from one leaf right to the base of the next leaf and in having axillary inflos. S. Nigeria, mentions one in Camaroon that is "not the same species".

This species is common in cultivation.
