The Boraginales are now universally accepted as monophyletic and firmly placed in Lamiidae. However, a consensus about familial classification has remained elusive, with some advocating recognition of a single, widely variable family, and others proposing recognition of several distinct families. A consensus classification is proposed here, based on recent molecular phylogenetic studies, morphological characters, and taking nomenclatural stability into consideration. We suggest the recognition of eleven, morphologically well-defined and clearly monophyletic families, namely the Boraginaceae s.str., Codonaceae, Coldeniaceae fam. nov., Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. Descriptions, synonomy, a taxonomic key, and a list of genera for these eleven families are provided, including the new family Coldeniaceae (monogeneric) and Namaceae (segregated from Hydrophyllaceae and comprising Nama, Eriodictyon, Turricula, and Wigandia), the latter necessitating a revised circumscription of a more morphologically coherent Hydrophyllaceae.

In pre-molecular times most scientists accepted this circumscription of Boraginaceae (e.g., Chadefaud & Emberger, 1960;Melchior, 1964b;Takhtajan, 1980Takhtajan, , 1997 Cronquist, 1981 Cronquist, , 1988Thorne, 1992), although some authors recognized one or the other subfamily at the family level. For example, Svensson (1925) andDi Fulvio (1978) removed Cordioideae, Heliotropioideae and Ehretioideae to Heliotropi aceae based on embryological studies, while Merxmüller (1960), Dahlgren (1980), and Takhtajan (1987) treated Wellstedioideae at the family level as Wellstediaceae. Conversely, Hoplestigmataceae, Hydrophyllaceae, and Lennoaceae were generally accepted as distinct families. However, the close relationships of these taxa to traditional Boraginaceae has been widely acknowledged by several authors (e.g., Jussieu, 1789; Baillon, 1891;Peter, 1893;Svensson, 1925; Chadefaud & Emberger, 1960; Melchior, 1964a, c;Takhtajan, 1980; Cronquist, 1981 Cronquist, , 1988. For example, Baillon (1891) defined the Boraginaceae as comprising nine series, which included both Boraginaceae and Hydrophyllaceae in their traditional circumscriptions. Chadefaud & Emberger (1960) considered Boraginaceae, Hoplestigmataceae, Hydrophyllaceae, and Lennoaceae to form a natural group within the order Tubiflorales. Takhtajan (1980) included these same families in the suborder Boraginineae.On the other hand, three groups historically associated to Boraginaceae have been clearly sho...

“…Currently, a concept of six sub‐families (Codonoideae, Wellstedioideae, Cordioideae, Ehretioideae, Heliotropioideae and Boraginoideae) is still widely accepted. However, a taxon of ordinal rank (Boraginales), comprising six smaller families (Boraginaceae s.s., Hydrophyllaceae, Heliotropiaceae, Cordiaceae, Ehretiaceae, Codonaceae and Wellstediaceae) is increasingly being used instead of Boraginaceae s.l (Böhle and Hilger , Ferguson , Smith et al , Gottschling et al , , Stevens , Hilger et al , Cohen , Refulio‐Rodriguez and Olmstead , Weigend et al ).…”

Taxonomic revision of the genus Heliotropium (Boraginaceae s.l.) in south Yemen

The flora and fauna of Arabia, particularly southern Yemen, has recently attracted the interest of many authors. In this study, the genus Heliotropium L. (Boraginaceae) is taxonomically revised in southern Yemen. Ten species are recognized. Nomenclature, typification, representative specimens and a diagnostic key to all species are provided, along with their distribution in southern Yemen. The taxonomically most valuable characters in the genus are those of flowers (calyx, corolla, androecium and gynoecium) and nutlets, and those characters are thoroughly investigated and discussed. Both light and scanning microscopy are used in the investigation. Papillate anther apices (brush-like) were recognized in some species. Connate anthers and deep or shallow ventral circular depressions on the nutlets were found to be useful in distinguishing members of H. sect. Orthostachys (viz. H. strigosum, H. rariflorum and H. ovalifolium), while winged nutlets were found only in H. pterocarpum. The length and hairiness of the style and stigma also proved to be taxonomically useful.

Phylogenetic relationships of the monotypic genera Halacsya and Paramoltkia and the origins of serpentine adaptation in circum‐mediterranean Lithospermeae (Boraginaceae): insights from ITS and matK DNA sequences

Halacsya and Paramoltkia are monotypic and partially sympatric genera in the Balkans, with no clear relationships among extant Lithospermeae due to striking morphological autapomorphies and scarcity of phylogenetic analyses in this group. The two species H. sendtneri and P. doerfleri show a strict selectivity for serpentine soils, posing the question whether this edaphic specialization reflects a common ancestry or a parallel process of adaptive evolution in unrelated lineages. DNA sequences from the nuclear ITS and chloroplast matK regions were generated from multiple accessions of Halacsya and Paramoltkia, and from representatives of 16 other genera of Mediterranean Lithospermeae. SEM analyses of pollen morphology were also conducted to test relationships indicated by molecular phylogenies. Parsimony analyses retrieved a clade of morphologically well differentiated monotypic Lithospermeae including Halacsya and Paramoltkia. ITS provided a better resolution of relationships and showed the two genera to be sistergroups close to Mairetis and Moltkiopsis, and no affinity to Moltkia as supposed by past authors. Pollen characters corroborated the phylogenetic link between the two Balkan genera. Five further monophyletic clades were recognised: Onosma‐Echium, Moltkia, Lithospermum s.l., Arnebia‐Macrotomia, and Alkanna‐Podonosma. Mapping the edaphic preferences of Lithospermeae onto molecular cladograms showed that serpentinophytism as an obligate condition originated separately in the clade of monotypic genera and in that of Onosma‐Echium. In Halacsya and Paramoltkia it represents an early ecological synapomorphy which probably originated in situ from non‐serpentine ancestors related to Moltkiopsis and Mairetis.
