A synopsis of Salvia sect. Gardoquiiflorae (Lamiaceae), with a note on the origins of Caribbean Salvia species

Abstract

Salvia subg. Calosphace sect. Gardoquiiflorae is re-examined, and three species, all endemic to Hispaniola (Greater Antilles), are recognized. The names S. brachyloba, S. buchii and S. selleana are here lectotypified. Detailed morphological descriptions, distribution maps, information about habitat, and an identification key to the species are provided. In addition, preliminary results of a phylogeographical study of West Indian endemic species identified two colonization events. A group of high-elevation Hispaniolian endemic species is closely related to species of Salvia from the Andes.
