Two New Species of Coussarea and a New Combination in Faramea (Rubiaceae, Coussareeae) from the Guianas
During the preparation of the treatment of the family Rubiaceae for the Flora of the Guianas, two new species of Coussarea were discovered. One species, Coussarea longilaciniata, was collected in Guyana and is characterized by its long-lanceolate calyx lobes; the other,
C. spicata, is from French Guiana and is unique in the genus by its spicate inflorescences. In addition, Faramea sessiliflora var. pedunculata is here elevated to the species level, and a new description of F. sessiliflora is also provided in view of the re-delimitation
of this species.
