摘要
Circumscription of the tribe Cinchoneae (Rubiaceae) is reconsidered on the basis of a cladistic analysis of structural data comprising 48 characters (164 states). It is concluded that the tribe Cinchoneae, in order to be monophyletic, should be restricted to comprise Capirona, Cephalodendron, Cinchona, Cosmibuena, Dolicholobium, Ferdinandusa, Joosia, Ladenbergia, Macrocnemum, and Remijia. It is also suspected, on insufficient evidence, that Maguireocharis, Pimentelia, and Stilpnophyllum belong here. Alseis, Calycophyllum, Schizocalyx, and Wittmackanthus form a monophyletic group possibly related to the Cinchoneae. A new tribe, Calycophylleae, is proposed to accommodate them. Hillia, which is possibly the sister group of the Cinchoneae, is retained in a separate tribe. Coptosapelta, Corynanthe, Crossopteryx, Hymenodictyon, Luculia, Mitragyna, Mussaendopsis, Paracorynanthe, Pausinystalia, and Uncaria are referred to the same tribe, for which the name Coptosapelteae has to be adopted. Probably also Greeniopsis belongs here. The genera Cigarilla, Coutarea, and Exostema, and possibly Syringantha and Wernhamia, seem to be most closely related to Portlandia and should be transferred to the tribe Condamineeae. Bouvardia, Coursiana, Danais, Duidiana, Dunnia, Heterophyllaea, Hindsia, Lecanosperma, Manettia, Merumea, Neohymenopogon, and Schismatoclada should be provisionally transferred to the tribe Hedyotideae, which is suspected to be polyphyletic, however. No conclusive results were reached concerning the position of Balmea, Blepharidium, Emmenopterys, and Suberanthus, the position of them remaining uncertain.
