The 52 species (including the weed species Heliotropium curassavicum and H. indicum) of the Boranginaceae known from Panama are described and information on their distribution and keys for their identification are given. Eight of these species are described as new, 5 in the genus Cordia and 3 in Tournefortia. Most genera of Panamanian Boranginaceae are South American in origin. More than half of the species are widespread in the Neotropics, but the remainder show stronger affinities with the rest of Central America than with South America or the West Indies.<new para>ADDITIONAL ABSTRACT:<new para>Notes are given on the phytogeographic relations of Panamanian Boraginaceae and a systematic treatment is given for the family which includes 3 genera of trees or shrubs (Cordia, Bourreria and Ehretia).
