The amazon lily Eucharis sanderi is a rare species endemic to western Colombia, with few locality records known. We documented the occurrence of the species for the first time on Isla Gorgona, near the Pacific coast of Colombia, based on a specimen collected in May, 2011. Isla Gorgona is an important protected area for the conservation of threatened species such as E. sanderi. We recommend that research be conducted to determine the conservation status of the population of this species on the island.
