Summary. Three new species of Barleria L. (Acanthaceae) are described from the Antsiranana region of northern Madagascar: B. speciosa I. Darbysh., B. glandulostamina I. Darbysh. and B. microcalyx I. Darbysh. Two subspecies are recognised in the second of these, subsp. glandulostamina and subsp. pseudohumilis I. Darbysh. The sectional placement and species affinities of each of the new species are discussed and the conservation status of each taxon is assessed: all are considered to be globally threatened.
