Several changes are proposed in the taxonomy and nomenclature of some Mexican members of the Polemoniaceae. Bonplandia linearis Rob. is considered only as a minor variant of B. geminiflora Cav. Cobaea biaurita Standl. proves also to be a taxonomic synonym of C. stipularis Benth. Loeselia greggii S. Wats. is the correct name of the species most often named L. scariosa (Mart. & Gal.) Walp. and the name L. pumila (Mart. & Gal.) is recognized for the plant erroneousely identified as L. ramosissima (Mart. & Gal.) Walp. Polemonium melindae is described as a new species on the basis of specimens collected in Chihuahua, Durango, Guanajuato and Querétaro. It differs from P. pauciflorum S. Wats. in its wider, longer and lemmon-colored corolla and in its wider calyx lobes.
