Cortesia is a halophytic and monotypic genus endemic to Argentina that belongs to Ehretiaceae (Boraginales). It is morphologically distinct from the other members of the family in having cuneate leaves with a 3-dentate apex, an involucrum of fused bracts, spatulate calyx lobes, and white drupes with a two-parted endocarp. Its single species, Cortesia cuneifolia, is here treated and illustrated based on the study of numerous herbarium collections. Additionally, a lectotype is designated for the name to assure its reliable application. Furthermore, the species is recorded for the first time in Tucumán province.
