A new species of Argyreia (Convolvulaceae) from Thailand is described and illustrated: A. albiflora. The morphological distinctions of this new species and its relationships with allied species are discussed. Micromorphological evidence is presented using scanning electron microscopy (SEM) and light microscopy (LM) demonstrating that microscopic features of the upper leaf surface are useful in separating species that are similar on a macromorphological level.Mahidol UniversityAgricultural and Biological SciencesArticleSCOPUS10.11646/phytotaxa.204.3.5
