Boraginaceae, the borage or forget-me-notfamily, includes about 2,000 species of shrubs, trees, and herbs in 146 to 156 genera with a worldwide distribution.
Mertensia is a genus of flowering plants in the family Boraginaceae. They are perennial herbaceous plants with blue or sometimes white flowers that open from pink-tinged buds. Such a change in flower color is common in Boraginaceae and is caused by an increase of pH in the flower tissue. Mertensia is one of several plants that are commonly called "bluebell". In spite of their common name, the flowers are usually salverform (trumpet-shaped) rather than campanulate (bell-shaped).
Phacelia is a genus of about 200 species of annual or perennial herbaceous plants in the borage family, native to North and South America. California is particularly rich in species with over 90 recorded in the region.
Boraginales is an order of flowering plants in the asterid clade, with a total of about 125 genera and 2,700 species. Different taxonomic treatments either include only a single family, the Boraginaceae, or divide it into up to eleven families. Its herbs, shrubs, trees and lianas (vines) have a worldwide distribution.
Nemophila parviflora, the smallflower nemophila, small-flowered nemophila or oak-leaved nemophila, is a dicot in the borage family, Boraginaceae, in the waterleaf subfamily, Hydrophylloideae.
Hoplestigma is a genus of flowering plants in the family Boraginaceae, although this is disputed, and it has been placed in its own family Hoplestigmataceae. Its two species are native to Cameroon, Gabon, Ivory Coast and Liberia in western tropical Africa.
Heliotropioideae was a subfamily of the flowering plant family Boraginaceae, comprising roughly 450 species. A 2016 revision of the Boraginales recognises it as a distinct family, Heliotropiaceae.
Boraginoideae is a subfamily of the plant family Boraginaceae s.s, with about 42 genera. That family is defined in a much broader sense in the Angiosperm Phylogeny Group (APG) system of classification for flowering plants. The APG has not specified any subfamilial structure within Boraginaceae s.l.
Wigandia is a genus of flowering plants within the waterleaf subfamily, Hydrophylloideae. They are found mainly in Central America and South America, though one or two species are found as far north as the United States. Some are grown as ornamental plants and will flourish in most Mediterranean or temperate regions. The genus is named for Johann Wigand, German Lutheran cleric and theologian, and Bishop of Pomesania.
Phacelia pedicellata is a species of flowering plant in the borage family, Boraginaceae. Its common names include specter phacelia and pedicellate phacelia. It is native to the southwestern United States and Baja California, where it can be found in several types of habitat, including creosote bush scrub and Joshua tree woodland.
Phacelia stellaris is a rare species of flowering plant in the borage family, Boraginaceae, known by the common names star phacelia and Brand's phacelia.
Heliotropiaceae are a cosmopolitan family of flowering plants with approximately 450 species worldwide, though it is concentrated especially in the tropics and subtropics.
A stinging plant or a plant with stinging hairs is a plant with hairs (trichomes) on its leaves or stems that are capable of injecting substances that cause pain or irritation.
Phacelia covillei is a North American species of annual forbs in the borage family. It is native to the eastern and central United States in scattered locations from Missouri to Maryland and North Carolina.
Phacelia dubia is an annual forb native to the eastern United States, that produces cream colored or light blue flowers in early spring.
Coldenia, named after C. Colden, is a monotypic genus of flowering plants traditionally included in the borage family, Boraginaceae sensu lato. It was assigned to the subfamily Ehretioideae, but molecular data revealed it to be more closely related to the genus Cordia, so that other authors placed in Cordioideae. Subsequently, it was placed in its own family, Coldeniaceae, within the Boraginales order, by the Boraginales Working Group.
Euploca is an almost cosmopolitan genus of plants with around 100 species. It was first described by Thomas Nuttall in 1837. While part of the broadly defined Boraginaceae in the APG IV system from 2016, a revision of the order Boraginales from the same year includes Euploca in the separate family Heliotropiaceae. Its species used to be classified in the genera Hilgeria and Schleidenia and in Heliotropium sect. Orthostachys, but were found to form an independent lineage in a molecular phylogenetic analysis, more closely related to Myriopus than to Heliotropium. While many species use the C4 photosynthetic pathway, there are also C3–C4 intermediate species. Species have leaves with a C4-typical Kranz anatomy.
Phacelia lyallii, common name Lyall's phacelia, is a species of plant in the family Boraginaceae. Classifications in older literature place it within the Hydrophyllaceae.
