It is usually somewhat hairy in texture, with glabrous, linear to lance-shaped leaves a few centimeters long.

The flower has five white, glabrous petals, each with two lobes, and five hairy sepals at the base.

This species is quite similar to Cerastium arvense, but it may be distinguished by the erect peduncles bearing the ripe fruits.

It is limited to northwestern Italy, where it can be found in the Apennines of Liguria and Piedmont.

This is a serpentine endemic,[2] growing in ultramafic outcrops and mountain scrublands.
