Abstract
A new lithophytic species of Gesneria was discovered during a recent research expedition to the Dominican Republic. Gesneria clasei J.L.Clark is a locally endemic species known from a single population in the Sierra de Bahoruco in the southwestern province of Barahona in the Dominican Republic. Images and a discussion are provided to differentiate Gesneria clasei from congeners that share tubular red corollas. Based on IUCN guidelines, a preliminary conservation status of Critically Endangered (CR) is assigned to G. clasei.
Resumen
Una nueva especie litófita de Gesneria fue descubierta durante una reciente expedición de investigación a la República Dominicana. Gesneria clasei J.L.Clark es una especie localmente endémica conocida de una sola población en la Sierra de Bahoruco, lado suroeste de la provincia de Barahona, República Dominicana. Se proporcionan imágenes y una discusión para diferenciar a Gesneria clasei de otras especies similares que comparten corolas rojas tubulares alargadas. Con base en las directrices de la UICN, se le asigna a G. clasei la categoría preliminar En Peligro Crítico (CR).
