PLANT FAMILY: Costaceae
BOTANICAL NAME: Costus albus
FORMAL SCIENTIFIC NAME:
This African species is placed in synonymy with Costus dubius (PID#3597) 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)
It was included in J. Koechlin's Flore du Gabon (1964) and also in his Flore du Cameroun (1965). He described as basal flowering, one flower per bract. Dr. Paul Maas has been working on a new monograph for the African Costus, and it will be interesting to find out if he keeps this species name or includes it in C. dubius as Locke did in the Flora of East Africa.
The African Plant Database lists this species as a syn. For C. dubius.
