Resumen
Se realiza un listado de la flora endémica de las bioregiones de la costa de Ecuador, las especies son categorizadas según los criterios UICN con la finalidad de que sean parte de los programas de conservación. Se registra un total de 109 especies endémicas de ambas bioregiones que se encuentran presentes en Ecuador: 96 spp. del Chocó y 31 spp. del BSDPE. De estas, se categorizaron 121 spp., debido a que 6 spp. habían sido previamente categorizadas. La diversidad a nivel de familias y especies de plantas endémicas del Chocó presentes en Ecuador es distintivamente superior (3:1) en comparación con las endémicas del BSDPE. Entre las categorías asignadas, preocupación menor (LC) comprende la mayor parte de flora endémica encontrada en las dos bioregiones, seguido de vulnerable (VU B2 abiii), CR y EN apenas están representadas por una especie cada una. Los hábitos de las plantas en las dos bioregiones son similares, los más abundantes tanto para el CHOCÓ y el BSDPE son árboles (A) con 30 y 12 spp, sin embargo, hay una diferencia contrastante entre las epifitas de cada bioregión, Chocó 33 spp. versus BSDPE 0 spp.
A checklist of the bioregional endemic flora on the coast of Ecuador is achieved. The recorded species are categorized according to the IUCN criteria to be included on conservation programs. A total of 109 species endemic to the Choco and EPDDF that are also present in Ecuador have been found: Choco 96 spp., EPDDF 31 spp. One hundred and five spp. have been categorized herein, only additional four spp. have been previously categorized. The diversity at family and genera ranks of plants endemic to Choco that are also present in Ecuador is distinctively higher (3:1) in contrast to the endemic to EPDDF. Among assigned categories, Least Concern (LC) encompasses most of endemic flora that occur in both bioregions, that is followed by Vulnerable (VU B2 abiii), meanwhile CR and EN are represented by one species each. On both bioregions the plant habits are similar, trees (A) is the most diverse habit in Choco and EPDDF, those represented by 30 and 12 spp., respectively. A conspicuous difference on epiphytic endemic flora has been observed, Choco 33 spp. against EPDDF 0 spp.
