Notes on the nomenclature of Lithospermum (Boraginaceae)


  • James I. Cohen Weber State University



Boraginaceae, Lithospermum, Macromeria, Onosmodium


Two taxonomic and nomenclatural issues in Lithospermum are addressed. The new combination L. thurberi based on Onosmodium thurberi is made, and L. macromeria (Macromeria viridiflora) is included as a heterotypic synonym. Lithospermum bejariense and Onosmodium bejariense are treated here as two distinct taxonomic entities.
