The two new species described here have been confused mainly with C. lanata, C. mexicana and C. salvadorensis.  Question:  Are foliar trichomes useful to distinguish species?  Taxon:  Species of Clethra.  Study site:  Central and southern mountain ranges of Honduras.  Methods:  Relevant literature on Clethra was reviewed and specimens from six herbaria were examined. Type material from all morphologically similar species, as well as those taxa with which the two new species have previously been confused were compared.  Results: Clethra albertinae and C. standleyana are described and illustrated as new and endemic species from Honduras, both belong to ser. Tomentosae. Clethra albertinae is most closely related to C. licanioides, a species endemic to Guatemala, and C. standleyana is most closely related to C. nicaraguensis, a widespread species that occurs from Mexico (Chiapas) to Nicaragua. Based on the IUCN Red List a conservation assessment of Vulnerable and Endangered is recommended for both new species. An updated list and key to the nine species of Clethra for the flora of Honduras is proposed.  Conclusions:  The foliar trichomes turned out to be diagnostic and in combination with characters of the inflorescences can used to separate of all Honduran species of Clethra. In Central America, Honduras is the third country with most species rich of this genus after Guatemala and Costa Rica.]]></p></abstract>

Las dos especies nuevas se han confundido en el pasado principalmente con C. lanata, C. mexicana y C. salvadorensis.  Pregunta:  ¿Son útiles los tricomas foliares para distinguir especies?  Taxón:  Especies of Clethra.  Sitio de estudio:  Cordilleras del centro y sur de Honduras.  Métodos:  Se revisó literatura relevante sobre Clethra y examinaron especímenes de seis herbarios. Se comparó con material tipo de las especies morfológicamente similares, así como aquellos taxones con los que las dos especies nuevas se habían confundido.  Resultados: Clethra albertinae y C. standleyana se describen e ilustran como especies nuevas y endémicas de Honduras, ambas pertenecen a la ser. Tomentosae. Clethra albertinae está más estrechamente relacionada con C. licanioides, una especie endémica de Guatemala, y C. standleyana está más estrechamente relacionada con C. nicaraguensis, una especie muy extendida que se encuentra desde México (Chiapas) hasta Nicaragua. Con base en la Lista Roja de la UICN se recomienda una evaluación de conservación de Vulnerable y en Peligro para ambas especies nuevas. Se propone una lista actualizada y clave de las nueve especies de Clethra para la flora de Honduras.  Conclusiones:  Los tricomas foliares resultaron ser diagnósticos y en combinación con caracteres de las inflorescencias pueden usarse para separar todas las especies hondureñas de Clethra. En Centroamérica, Honduras es el tercer país con mayor riqueza de especies de este género después de Guatemala y Costa Rica.]]></p></abstract>
