Additional new combinations in Sesamum L. (Pedaliaceae: Sesameae)

Background: Ongoing systematic studies in the African flora necessitate periodic nomenclatural adjustments and corrections. Objectives: To effect requisite nomenclatural changes. Method: Relevant literature was surveyed and requisite nomenclatural transfers provided. Results: The new combination Sesamum byngianum Christenh. proposed for Josephinia africana Vatke is superfluous as an available synonym exists. Conclusions: The new combination Sesamum rosaceum (Engl.) J.C. Manning & Magee is also provided for Josephinia africana Vatke. Three new sectional combinations are provided to accommodate the species previously placed in Ceratotheca Endl., Josephinia Vent. and Dicerocaryum Bojer in the current infrageneric classification of Sesamum.
