According to the ovary, entire or lobed, genera of the Boraginaceae has been divided into four subfamilies. These subfamilies have been faced with many taxonomic opinions since long time ago.

70 species and exhibits a wide range of nutlet variation. Currently, the evolutionary relationships among species of Lappula have not been examined; therefore, to elucidate phylogenetic relationships and morphological evolution within Lappula and related genera, we conducted phylogenetic analyses with matrices that include 48 species as well as four DNA regions .
