Ehretiaceae
Clades: Boraginales; Lamiidae; Asteranae; Angiospermae; Plants.
Taxonomy
In the Apg3 classification Ehretiaceae is treated as Subfamily Ehretioideae of Boraginaceae, the only family in the Order Boraginales. The Apg4 classification does the same.
The genus Cordia has been analysed. Cordia can be split in 4 subgenera:
Varronia, type Cordia varronia.
Collococcus, type Cordia collococca, with Pilicordia, Physoclada, Superbiflorae.
Myxa subclade, type Cordia myxa.
Sebestena, type Cordia sebestena, including Gerascanthus, Rhabdocalyx, Auxemma, Patagonula, and Saccellium.
Plant theory
Ehretiaceae is tretated as a Family in the Order Boraginales. The clades Heliotropioideae and Cordiodeae are included in Ehretiaceae.
In the first version of the Pant theory Cordiaceae was in Subphase 5 and Heliotropiaceae was in Subphase 4. Further studies, cases and provings show that both belong in Subphase 6. This fits the recent phylogenetic studies.
Genera
Heliotropioideae: Heliotropium, Tournefortia.
Cordioideae: Helio, Cordia, Saccellium
Ehretioideae: Bourreria, including Hilsenbergia, Cortesia, Ehretia, including Carmona and Rotula, Halgania, Lepidocordia, Menais, Patagonula, Rochefortia, Tiquilia, Americas
