SEDUM SALVADORENSE (CRASSULACEAE), A RARE ENDEMIC SPECIES AND FLORA REDISCOVERED FOR EL SALVADORFT SEDUM SALVADORENSE (CRASSULACEAE), UNA ESPECIE ENDEMICA Y RARA REDESCUBIERTA PARA LA FLORA DE EL SALVADOR

摘要

Sedum salvadorense is described from its native habitat and locality and photographs of live plants are presented for the first time, 90 years after the published discovery of collections by Paul C. Standley in the Apaneca, Ahuachapan (western El Salvador) in an expedition from January 1922. The absence of reports from either the original collection locality or anywhere else suggested that the species was extinct. We present two new collection localities, representing a rediscovery for the Flora of El Salvador. This species occurs in very specific habitats in undisturbed areas, and grows on cliff rocks. S. salvadorense is very rare and poorly studied from ecological, phenological and geological perspectives and represents the only species of the genus occurring in El Salvador.
