This African species is newly described 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, http://www.ingentaconnect.com/content/nhn/blumea/2016/00000061/00000003/art00010)
Costus aureus is characterized by flowers that are completely yellow and arranged in an inflorescence terminating a leafy shoot and composed of green and generally appendaged bracts. Vegetatively it looks very similar to C. lucanusianus by having a rim at the base of the ligule. However, this rim is hairless in C. aureus, while it is distinctly hairy in C. lucanusianus. â€” Type: Berg 186 (holo U 4 sheets [U0123675, U0123676, U0123677, U0123678]; iso B, MO, NY), Ivory Coast, near AkoupÃ© (NW of Abidjan), 31 July 1972.
