Editorial Note
All of the species treated by Bean under the name Lithospermum have since been referred to other genera – either Lithodora and Glandora, though species included in the current concept of Lithospermum are cultivated in our study area. The brief text below is supplied pending a full, revised account of the genus, to be provided when funds are available.
