Although Appunia Hook. f. has been synonymized by some recent authors with Morinda L., it is here provisionally recognized as a Neotropical genus, with the new species A. megalantha C. M. Taylor & Lorence found in wet lowland forests of northwestern Colombia, northern Peru, and perhaps Ecuador and easily separated from other species of Appunia by its climbing habit and relatively large corollas with six lobes. Two new species of Coutarea Aubl. with actinomorphic corollas expand its known diversity in seasonal and dry inter-Andean valleys, with C. coutaportloides C. M. Taylor of southwestern Ecuador and C. fuchsioides C. M. Taylor of northeastern Peru both similar to C. andrei Standl. A second species of Patima Aubl., P. minor C. M. Taylor (Hamelieae) from Guyana, doubles the number of species known and expands the morphological variation in the genus to include 4-merous flowers. A fourth species of Rosenbergiodendron Fagerl., R. reflexum C. M. Taylor & Lorence from Peru, has subglobose fruits and relatively large corollas, ca. 34.5 cm long.
