Dasynotus is a monotypic genus of flowering plants belonging to the family Boraginaceae, it only contains one known species, Dasynotus daubenmireiI.M.Johnst.. [1]
Its native range is north-western USA and it is only found in Idaho. [1]
The genus and species were circumscribed by Ivan Murray Johnston in J. Arnold Arbor. vol.29 on page 233 in 1948. [1]
It has the common name of 'Daubenmire's Dasynotus'. [2]
The Latin specific epithet of daubenmirei is in honour of Dr Rexford Daubenmire (1909- ), [3] an American ecologist that went to the University of Minnesota, where he was taught by William Skinner Cooper (1884–1978), among his fellow students at Minnesota were Henry J. Oosting, Murray Fife Buell and Frank Edwin Egler. [4]
Dasynotus has a unique morphology, when compared to other species of the Boraginaceae family, as it has large white salverform (composed of united petals forming a tube that spreads at the open end) corollas with long horn-like faucal appendages and large nutlets covered with sparse trichomes (hairs). [5]
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).
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.
Euplassa is a genus of flowering plants in the protea family. It is native to tropical South America, including Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela.

Harpagonella is a genus of flowering plants in the borage family. They are known as the grappling-hooks, because of the appearance and function of their fruits. The strange fruits are two small nutlets enclosed in a burlike calyx, which is armed with numerous spines covered in minute, hooked barbs. These diminutive, annual plants are found in sandy, clayey, and gravelly soils, and have small white flowers. This genus is native to North America, and is found in southern California, southern Arizona, northern Sonora, and the Baja California peninsula.
Boraginoideae is a subfamily of the flowering 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.
