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).

<i>Mertensia</i> Genus of flowering plants in the borage family Boraginaceae

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).

<i>Harpagonella</i> Genus of flowering plants in the borage family Boraginaceae

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.
