We believe this character can be variable, and a clear overlap suggests it may not be possible to differentiate the Gabonese material from the Cameroonian based on this feature. In addition, the ovary was mentioned as sessile on the Gabonese material by the authors of the monograph, but close observation shows that this material has a distinct gynophore, with the filament not inserted at the base of the ovary.
