Greeneocharis circumscissa is a species of flowering plant in the borage family,[2] known by the common name cushion cryptantha. It is native to western North America from Washington to Baja California to Colorado and it is also found in Argentina .[3] It grows in sandy or gravelly types of habitat, from mountains to desert, below 9,500 m (31,200 ft) above sea level.[4]
This is an annual herb producing a short, bristly, multi-branched stem tangled into a mat no more than 10 centimeters tall. It grows from a red taproot which dries purple. The leaves are up to 1.5 centimeters long, linear to widely lance-shaped, and densely hairy to bristly. The inflorescence is a length of developing fruits with a dense cluster of up to 5 flowers at the tip. The flower has a five-lobed white corolla with yellow appendages at the top of its tube. It flowers between April and August.[4]
It was first published in Bull. Torrey Bot. Club vol.36 on page 677 in 1909.[2]
The Latin specific epithet circumscissa is derived from the Latin for "cut around" because the upper half of the fruiting calyx falls away when the nutlets are ripe.[5]
It has 3 known variants;[2]
