Boraginales
Boraginales is an order of flowering plants in the asterid clade. It includes the Boraginaceae and a number of other families, with a total of about 125 genera and 2,700 species. Its herbs, shrubs, trees and lianas (vines) have a worldwide distribution. Taxonomy History The classification of plants now known as Boraginales dates to the ''Genera plantarum'' (1789) when Antoine Laurent de Jussieu named a group of plants Boragineae, to include the genus ''Borago'', now the type genus. However, since the first valid description was by Friedrich von Berchtold and Jan Svatopluk Presl (1820), the botanical authority is given as Juss. ex Bercht. & J.Presl, where the ''ex'' refers to the prior authority of Jussieu. Lindley (1853) changed the name to the modern Boraginaceae. Jussieu divided the Boragineae into five groups. Since then Boraginaceae has been treated either as a large family with several subfamilies, or as a smaller family with several closely related families. The famil ...

Hoplestigmataceae
''Hoplestigma'' is a genus of flowering plants in the family Hoplestigmataceae.Vernon H. Heywood, Richard K. Brummitt, Ole Seberg, and Alastair Culham. 2007. ''Flowering Plant Families of the World''. Firefly Books: Ontario, Canada. . One study of pollen suggested that ''Hoplestigma'' might be related to the family Ehretiaceae.Joan W. Nowicke and James S. Miller. 1989. "Pollen morphology and the relationships of Hoplestigmataceae". ''Taxon'' 38(1):12-16. In a comparison of chloroplast DNA sequences in 2014, ''Hoplestigma'' formed a strongly supported clade with ''Coldenia'' and genera that have always been placed in Cordiaceae.Maximilian Weigend, Federico Luebert, Marc Gottschling, Thomas L.P. Couvreur, Hartmut H. Hilger and James S. Miller. 2014. "From capsules to nutlets — phylogenetic relationships in the Boraginales". ''Cladistics'' 30(5):508-518. . The authors of that study recommended that ''Hoplestigma'' and ''Coldenia'' be included in Cordiaceae. However, it was traditi ...

Boraginaceae
Boraginaceae, the borage or forget-me-not family, includes about 2,000 species of shrubs, trees and herbs in 146, to 156 genera with a worldwide distribution. The APG IV system from 2016 classifies the Boraginaceae as single family of the order Boraginales within the asterids. Under the older Cronquist system it was included in Lamiales, but it is now clear that it is no more similar to the other families in this order than they are to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae in eleven distinct families: Boraginaceae ''sensu stricto'', Codonaceae, Coldeniaceae, Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some have petiol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heliotropiaceae
Heliotropiaceae is a cosmopolitan family of flowering plants with approximately 450 species worldwide, though it is concentrated especially in the tropics and subtropics. There are the following four genera in the family: * ''Heliotropium (''incl. ''Tournefortia'' L.) * ''Euploca'' Nutt. * ''Ixorhea'' Fenzl * '' Myriopus'' Small ''Ixorhea'' is sister to ''Euploca'' and ''Myriopus''. Together they form a clade sister to ''Heliotropium'', which comprises four major clades: ''Heliotropium'' sect. ''Heliothamnus'' I.M.Johnst., Old World ''Heliotropium'', ''Heliotropium'' sect. ''Cochranea'' (Miers) Post & Kuntze, and the ''Tournefortia''-clade, the latter comprising ''Tournefortia'' sect. ''Tournefortia'' and all remaining New World species of ''Heliotropium''. History Prior to a 2016 revision, Heliotropiaceae was considered a subfamily of the Boraginaceae: Heliotropioideae. Even before that, however, there was already some indication in the field that Heliotropiaceae deserved to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coldeniaceae
''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 Order, ORDER or Orders may refer to: * Categorization, the process in which ideas and objects are recognized, differentiated, and understood * Heterarchy, a system of organization wherein the elements have the potential to be ranked a number of d ..., by the Boraginales Working Group.

Asterid
In the APG IV system (2016) for the classification of flowering plants, the name asterids denotes a clade (a monophyletic group). Asterids is the largest group of flowering plants, with more than 80,000 species, about a third of the total flowering plant species. Well-known plants in this clade include the common daisy, forget-me-nots, nightshades (including potatoes, eggplants, tomatoes, chili peppers and tobacco), the common sunflower, petunias, yacon, morning glory, sweet potato, coffee, lavender, lilac, olive, jasmine, honeysuckle, ash tree, teak, snapdragon, sesame, psyllium, garden sage, table herbs such as mint, basil, and rosemary, and rainforest trees such as Brazil nut. Most of the taxa belonging to this clade had been referred to as Asteridae in the Cronquist system (1981) and as Sympetalae in earlier systems. The name asterids (not necessarily capitalised) resembles the earlier botanical name but is intended to be the name of a clade rather than a formal ranked name ...

Botanical Authority
In botanical nomenclature, author citation is the way of citing the person or group of people who validly published a botanical name, i.e. who first published the name while fulfilling the formal requirements as specified by the '' International Code of Nomenclature for algae, fungi, and plants'' (''ICN''). In cases where a species is no longer in its original generic placement (i.e. a new combination of genus and specific epithet), both the authority for the original genus placement and that for the new combination are given (the former in parentheses). In botany, it is customary (though not obligatory) to abbreviate author names according to a recognised list of standard abbreviations. There are differences between the botanical code and the normal practice in zoology. In zoology, the publication year is given following the author names and the authorship of a new combination is normally omitted. A small number of more specialized practices also vary between the recommendations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plant Taxonomy
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally not having any close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy. Background Classification systems serve the purpose of grouping organisms by characteristics common to each group. Plants are distinguished from animals by various trai ...

Echium Vulgare
''Echium vulgare'', known as viper's bugloss and blueweed,Dickinson, T.; Metsger, D.; Bull, J.; & Dickinson, R. (2004) ROM Field Guide to Wildflowers of Ontario. Toronto:Royal Ontario Museum, p. 203. is a species of flowering plant in the borage family Boraginaceae. It is native to most of Europe and western and central Asia''Flora Europaea''''Echium vulgare''/ref> and it occurs as an introduced species in north-eastern North America, south-western South America and the South and North Island of New Zealand. The plant root was used in ancient times as a treatment for snake or viper bites. If eaten, the plant is toxic to horses and cattle through the accumulation of pyrrolizidine alkaloids in the liver. Description It is a biennial or monocarpic perennial plant growing to tall, with rough, hairy, oblanceolate leaves. The flowers start pink and turn vivid blue, and are in a branched spike, with all the stamens protruding. The pollen is blue but the filaments of the stamens rema ...
