Mibora minima, the early sandgrass,[2] is a small (between 2 and 15 cm high) annual species of grass that is native in western and southwestern Europe.

It is an invasive species on both sides of the Canada–United States border from Lake Huron east to Maine.

It grows on moist sand in open vegetations.[3]
