Euploca is an almost cosmopolitan genus of plants with 168 species. [2] [4] It was first described by Thomas Nuttall in 1837. [1] [5] While part of the broadly defined Boraginaceae in the APG IV system from 2016, [6] a revision of the order Boraginales from the same year includes Euploca in the separate family Heliotropiaceae. [4] 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. [3] While many species use the C4 photosynthetic pathway, [7] there are also C3–C4 intermediate species. [8] [9] Species have leaves with a C4-typical Kranz anatomy. [3]
168 species are accepted. [2]
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.
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.
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.
Aerva is a genus of plants in the family Amaranthaceae. Its species are native to the palaeotropics, throughout continental Africa, Madagascar and smaller islands, through parts of the Middle East, India, and southeast Asia. Aerva javanica is an alien in northern Australia.
Heliotropium arboreum is a species of flowering plant in the borage family, Boraginaceae. It is native to tropical Asia including southern China, Madagascar, northern Australia, and most of the atolls and high islands of Micronesia and Polynesia. Common names include velvetleaf soldierbush, tree heliotrope, veloutier, and octopus bush. It is a shrub or small tree typical of littoral zones reaching a height of 3.6 m (12 ft), with a spread of about 5 m (16 ft).
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.
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.
Pycnanthemum is a genus of herbaceous plants in the mint family (Lamiaceae). Species in this genus are often referred to as "mountain mints" and they often have a minty or thyme-like aroma when crushed. All species of Pycnanthemum are native to the United States and Canada. The center of diversity for the genus is North Carolina with 13 of the 20 species having been collected therein. Nineteen of the 20 species of Pycnanthemum occur in the Eastern US and Canada, and one disjunct species occurs in California and Oregon.
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.
Bienertia is a flowering plant genus that currently is classified in the family Amaranthaceae s.l.. For long time, the genus was considered to consist only of one species, Bienertia cycloptera, but in 2005 and 2012, two new species have been separated.
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.
Myriopus is a genus of flowering plants in the borage and forget-me-not family Boraginaceae. Species in the genus are native to Latin America, the Caribbean, and Florida.
Euploca humilis, the dwarf tournefortia, is a species of flowering plant in the family Boraginaceae. It is native to Mexico, Central America, the Caribbean, Colombia, Venezuela, Guyana, and most of Brazil. Originally described by Linnaeus in 1753, molecular and morphological evidence led to its transfer from Tournefortia to Euploca in 2016.
Heliotropium hirsutissimum, the hairy heliotrope, is a species of flowering plant in the family Boraginaceae, native to the eastern Mediterranean; Greece, Turkey, Cyprus, the Levant, Egypt, and Libya. It contains a number of pyrrolizidine alkaloids. Grauer is listed as the authority by some sources.
