There are about 100 species of Dichptera Juss. in the world, distnbuted in tropical, subtropical regions of Asia and Afnca. This genus has many morphological charactenstics closing with Penstrophe Nees, but differs by the characteristics of anthers, inflorescences, bracts, and bracts. The present work is a taxonomic revision of the genus Diciiptera in Vietnam. Efforts have been made to describe the detailed morphological charactenstics of Diciiptera species found in Vietnam. The study is an effort to understand the morphological delimitation of Vietnamese Diciiptera species in a better way, and to clear up the confusions associated with their identification. A taxonomic key to the species along with updated nomenclature, distribution details, ecological notes, and three line-drawings are provided. All names of the species are typified. Morphological characteristics of the pollen grains of Diciiptera bupleuroides and Diciiptera chinensis d.ve presented for the first Ume.
Keywords: Acanthaceae, Diciiptera, morphology, taxonomy, Vietnam.
