Taxonomic Notes on <i>Rhynchosia meeboldii</i> : A New Synonym for <i>R. harae</i> (Fabaceae)

ABSTRACT A detailed study of the key characters employed in distinguishing Rhynchosia meeboldii from R. harae has led to the conclusion that the two taxa are conspecific and the two names are to be considered as heterotypic synonyms, the binomial R. harae having nomenclatural priority. This new synonym is supported by a detailed comparison of taxonomic features and other morphological evidence, as well as the distribution areas of the putative taxa. Furthermore, the study confirms that morphological traits of size and thickness of leaflets, apex of calyx lobes and hairs are critical for the identification of this species complex.
