A formal treatment of two taxonomic novelties in Coffea from southern Cameroon is given. In their habit the two species resemble the widespread C. brevipes in having mostly uniflorous inflorescences. The new species C. leonimontana is striking by its spathulate-acuminate leaf-tips. C. heterocalyx (C. brevipes var. heterocalyx, nomen) is unique in Coffea as the flowers possess a distinct calyx with unequal lobes which apparently develop postflorally.
