Published on 24 December 1999

The African genus Barteria, most recently treated as monospecific, is revised to comprise four species, three of which (B. dewevrei, B. fistulosa, B. nigritana) are myrmecophytes. The fourth species, B. solida, is described as new and does not house ants. It is confined to higher altitudes. A key to the four species is given and their distributions are mapped. Illustrations are provided of the new species as well as the ants that inhabit B. fistulosa. A note concerning the stipules and the extra floral nectaries of Barteria is added.
