The crown is spread out like a wheel to bell-shaped. Their color is blue, pink, or white. The corolla tube is short to absent. The gullet scales are short, bare, and ragged, they protrude from the crown. The stamens clearly protrude above the pharyngeal scales and almost start at the base of the crown. The stamens have a long, narrow appendage at the tip. The stylus do not protrude over the gullet scales and have a heady scar .

The fruits of the Klausen fruit are obovate, straight and wrinkled. Your attachment point is concave and surrounded by an annular bead.

Flower and dispersal ecology

The flowers are bluebells , carry nectar and have a scattering cone. They are pollinated by bees.

The spread is carried out by ants ( myrmecochory ).

distribution

The genus is restricted to the southwest of the Mediterranean. Four of the five species occur only in Northwest Africa, Corsica, Sardinia and the Tuscan Archipelago . Only the borage ( Borago officinalis ) is cultivated very widely and is often found wild.
