Coldenia, named after C. Colden, is a monotypic genus of flowering plants traditionally included in the borage family, Boraginaceae sensu lato . [2] 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. [3] Subsequently, it was placed in its own family, Coldeniaceae, within the Boraginales order, by the Boraginales Working Group. [4]
The sole species is Coldenia procumbens.
Boraginaceae, the borage or forget-me-notfamily, includes about 2,000 species of shrubs, trees, and herbs in 146 to 154 genera with a worldwide distribution.
Cordia is a genus of flowering plants in the borage family, Boraginaceae. It contains 228 species of shrubs and trees, that are found in tropical and subtropical regions worldwide. Many of the species are commonly called manjack, while bocote may refer to several Central American species in Spanish.
Geraniales is a small order of flowering plants, included within the rosid subclade of eudicots. The largest family in the order is Geraniaceae with over 800 species. In addition, the order includes the smaller Francoaceae with about 40 species. Most Geraniales are herbaceous, but there are also shrubs and small trees.
Geraniaceae is a family of flowering plants placed in the order Geraniales. The family name is derived from the genus Geranium. The family includes both the genus Geranium and the garden plants called geraniums, which modern botany classifies as genus Pelargonium, along with other related genera.
Pulmonaria (lungwort) is a genus of flowering plants in the family Boraginaceae, native to Europe and western Asia, with one species east to central Asia. According to various estimates there may be between 10 and 18 species found in the wild.
Heliotropium is a genus of flowering plants traditionally included in the family Boraginaceae s.l., but placed in the family Heliotropiaceae within the Boraginales order, by the Boraginales Working Group.. There are around 325 species in this almost cosmopolitan genus, which are commonly known as heliotropes. They are highly toxic to dogs and cats, as well as to humans.
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.
Bourreria is a genus of flowering plants in the borage family, Boraginaceae. Members of the genus are commonly known as strongbark or strongback. The generic name was chosen by Patrick Browne to honour German pharmacist Johann Ambrosius Beurer. The genus is native to the tropical Americas and to eastern Africa and Madagascar. American species are distributed from Mexico to northern South America, and in the Caribbean and Florida in the United States. The center of diversity is in the Caribbean, Central America, and Mexico. The eastern African species range from Ethiopia to Mozambique and to Madagascar, the Comoro Islands, and Mauritius.
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.
Wellstedia is a genus of flowering plants traditionally included in the family Boraginaceae s.l., but placed in its own family, Wellstediaceae within the Boraginales order, by the Boraginales Working Group.
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.
When the APG II system of plant classification was published in April 2003, fifteen genera and three families were placed incertae sedis in the angiosperms, and were listed in a section of the appendix entitled "Taxa of uncertain position".
Codon is a small genus of plants from South Africa in the family Codonaceae in the order Boraginales. The genus Codon comprises two species.
Heliotropiaceae are a cosmopolitan family of flowering plants with approximately 450 species worldwide, though it is concentrated especially in the tropics and subtropics.
Pseudomertensia is a genus of flowering plants in the family Boraginaceae. They are perennial herbs with blue or bluish purple flowers. Their natural range is from Iran to the Himalayas. None have been found in China or Russia. P. echioides, and the type species for the genus, P. elongata, are occasionally cultivated as ornamentals.
Cordia lutea, known as yellow cordia or in Spanish muyuyo, is a shrubby plant in the borage family (Boraginaceae), native to the Galápagos Islands, mainland Ecuador, Peru, and the Marquesas Islands in Polynesia. Common in the arid lowlands of the Galápagos, its relatively large yellow flowers make it easy to identify.
Selkirkia is a genus of flowering plants in the family Boraginaceae. Three species occur on the South American mainland and one, Selkirkia berteroi, the first of the genus to be reported, is an endemic on Robinson Crusoe Island off the coast of Chile. It was previously considered a monotypic genus.
Euploca is an almost cosmopolitan genus of plants with 168 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.
Huynhia is a genus of flowering plants belonging to the family Boraginaceae, from Asia.
