P. Stoffelen et al., COFFEA (RUBIACEAE) IN CAMEROON - A NEW SPECIES AND A NOMEN RECOGNIZEDAS SPECIES, Belgian journal of botany, 129(1), 1996, pp. 71-76
A formal treatment of two taxonomic novelties in Coffea from southern
Cameroon is given. In their habit the two species resemble the widespr
ead C. brevipes in having mostly uniflorous inflorescences. The new sp
ecies C. leonimontana is striking by its spathulate-acuminate leaf-tip
s. C. heterocalyx (C. brevipes var. heterocalyx, nomen) is unique in C
offea as the flowers possess a distinct calyx with unequal lobes which
apparently develop postflorally.
