Lithospermeae

Viper's bugloss Echium vulgare, copyright Emily Kloosterman.


Belongs within: Boraginaceae.

The Lithospermeae are a clade of plants in the Boraginaceae which have the style usually divided, and nutlets with a broad basal attachment scar (Långström & Chase 2002). This group includes the viper's buglosses of the genus Echium, some of which are widely grown as ornamentals though a few have become invasive species in some parts of the world.

Characters (from Långström & Chase 2002): Style usually divided at apex, with two to four stigmas; pollen colporate, heteropolar or prolate; nutlets with broad basal attachment scar, flat gynobase.
