Family Code: BORAGI Genus Code: LITHO3 Genus CN: stoneseed Genus Authority: L. Genus Summary: A genus of about 60 species, herbs (mostly perennials), nearly cosmopolitan. Recent studies strongly suggest that Onosmodium is better included in a broadened Lithospermum (Cohen & Davis 2009; Weigend et al. 2009), as Onosmodium is embedded within Lithospermum in a subclade also including L. tuberosum; morphologically, Onosmodium shows a subset of the characteristics in a broader and more diverse Lithospermum.
