VEGA, Michael S.; CERONI, Aldo  y  REYNEL, Carlos. Ecological observations and taxonomy of the genus Codonanthe (Mart.) Hanst. (GESNERIACEAE) at the Los Amigos River Basin (Madre de Dios - Peru). Ecol. apl. [online]. 2006, vol.5, n.1-2, pp.37-43. ISSN 1726-2216.

We present observations and collections of specimens of the genus Codonanthe (Mart.) Hanst. from the three main types of forests at Los Amigos River: aguajal, plain low forest or "bajío" and high terrace forest. We found two species: C. uleana and C. crassifolia; both of epiphytic habit; C. uleana was usually found associated with ants ("ant gardens"): Azteca sp., Camponotus femoratus and Crematogaster cf limata parabiotica. According to the type of habitat and to the amount of light received, we observed variations in the abundance and morphology of these epiphytic species. C. crassifolia is a new report to the flora of Madre de Dios.

Palabras clave : Codonanthe; epiphyts; ant gardens; parabiotic interactions; epiphytism.
