A new species of the genus Carica, found in forests in southeast Ecuador, is described. Carica palandensis Badillo, Van den Eynden & Van Damme is clearly distinguished from all other Carica species by its always compound leaves with 5to 9-petiolulate leaflets. RESUMEN. Se describe una nueva especie del g6nero Carica encontrada en los bosques del sureste del Ecuador. Carica palandensis Badillo, Van den Eynden & Van Damme se distingue claramente de las demds especies de Carica por sus hojas siempre compuestas con 5 a 9 folfolos petiolulados. In the course of an ethnobotanical inventory of wild edible plants in southern Ecuador, a new species of Carica was collected in Palanda in the Amazonian province of Zamora-Chinchipe. After the initial collection of a female plant in December 1995, a second visit was paid to the same area in June 1997, and as a result more material was collected of both male and female plants. The area where this species was discovered is under great pressure from land clearance for timber production, to the extent that the site of the December 1995 collection was completely cleared by June 1997 and the species no longer existed at this site.
