The genus Glandularia (Verbenaceae) in Brazil

Abstract

Glandularia J. F. Gmel. (Verbenaceae) is the largest genus in the tribe Verbeneae, with ca. 84 species distributed mainly in temperate North and South America. A complete taxonomic revision of Glandularia in Brazil is provided. Thirty-one species and one variety are present in Brazil, 11 of these being endemic, principally in the southern area of the country. A detailed morphological description is given for each taxon as well as a key for their identification, illustrations, synonymy, distribution, lists of selected specimens, and discussions about the relationships among closely related taxa. A new combination, G. tomophylla (Briq.) N. O'Leary & V. Thode, is here proposed, six new synonyms are suggested, and two lectotypes are designated for Verbena chamaedryfolia Juss. f. strigosa Chodat and V. humifusa Cham.
