Coutarea

Abstract: Wood samples of a number of Cinchoneae and Naucleeae sensu Schumann were studied, and the results compared with data found in the literature. On the whole the representatives of the Cinchoneae appeared to show a rather high degree of similarity among each other with the exception, however, of the genera Coutarea, Exostemma, Corynanthe, Crossopteryx, and Hymenodictyon. The creation of the tribe Coptosapelteae and its inclusion in the Ixoroideae seem to be corroborated by the particular character of the wood anatomy. The restriction of the Naucleeae to Nauclea L. ( Sarcocephalus Afzel.) is not supported by the anatomy of the wood.

Abstract: 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...
