Abstract:
Some important species of Ocimum are typified to avoid further confusion in the literature. O. x citriodorum Vis. is show to be correct name for the allohexaploid O. americanum sensu Pushpangadan and Sobti. O. americanum L. is the correct name for the widespread diploid species sometimes referred to as O. canum Sims. An interpretive epitype is provided. The relationships between the economically important varieties of O. basilicum L., and O. x citriodorum, O. minimum L. and O. tenuiflorun L. and the resultant taxonomic problems are explored with reference to crossability studies and chromosome numbers. O. tenuiflorum is reproductively isolated from all other taxa in this study. No viable seed was produced in crosses involving O. minimum, although nutlets were formed in some cases. O. minimum is recognized as a species here in order to reflect the morphological differences and the observed reproductive isolation. O. x citriodorum crosses with some varieties of O. basilicum but not others. All crosses between varieties of O. basilicum produced viable seed. This has important consequences which limit the usefulness of varietal names within the complex. It is suggested that a system of standardized descriptions is needed to allow accurate identification and unambiguous communication of forms within this economically and medicinally important group.
