Boraginaceae
Boraginaceae, the Borago, borage or forget-me-not family, includes about 2,000 species of shrubs, trees, and herbs in 146 to 154 genus, 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 the Lamiales, but clearly is no more similar to the other families in this order than it is to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae into 11 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 petiole (bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echium
''Echium'' is a genus of flowering plants in the family Boraginaceae that contains about 70 species and several subspecies. Species of ''Echium'' are native to North Africa, mainland Europe to Central Asia, and the Macaronesian islands where the genus reaches its maximum diversity. Twenty-nine species of ''Echium'' are endemic to the Canary, Madeira, and Cape Verde archipelagos. The continental species are herbaceous, whereas many of the endemic species of the Macaronesian islands are woody perennial shrubs. Etymology The Latin genus name ''Echium'' comes from the Greek ''echion'', referring to '' Echium plantagineum'' and itself deriving from ''echis'' (viper); the Greek term dates to Dioscorides, who noted a resemblance between the shape of the nutlets and a viper's head. The genus ''Echium'' was published by Carl Linnaeus in 1753. Cultivation and uses Many species are used as ornamental and garden plants and may be found in suitable climates throughout the world.

Endemic Flora Of The Canary Islands
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...
