Бурачникоцветные (Boraginales) 5/17/08—5/1/21
Boraginales is a valid taxonomic name at the rank of order for a group of flowering plants. When recognized, it includes Boraginaceae and closely related asterid families.
Boraginales is recognized in neither of two major classification systems, the Cronquist system and the APG III system, but has been recognized in some recent scientific papers. The circumscription of Boraginales is essentially identical to the circumscription of Boraginaceae sensu APG. The APG III system takes a broad view of Boraginaceae, including within it the traditionally recognized families Hydrophyllaceae and Lennoaceae based on recent molecular phylogenies that show that Boraginaceae, as traditionally defined, is paraphyletic over these two families. APG III includes Boraginaceae in the Euasterid I (lamiid) clade but this family is otherwise unplaced; its precise relationship to other families in the Euasterid I group remains unclear. In a phylogenetic study of DNA sequences of selected genes, Boraginales was resolved as sister to Lamiales sensu APG, but that result had only 65% maximum likelihood bootstrap support.
In the 2016 APG IV system Boraginales is an order with only one family Boraginaceae, which includes the former family Codonaceae.
In the Cronquist system, Boraginaceae (including Cordiaceae, Ehretiaceae, and Heliotropiaceae) and Lennoaceae were placed in Lamiales, and Hydrophyllaceae in Solanales.
