Otanthus is a genus of flowering plants in the chamomile tribe (Anthemideae) within the daisy family (Asteraceae or Compositae).

[2] Otanthus maritimus is a small pioneering perennial with a thick white down that covers both the stems and the small oval, slightly saw-toothed alternate leaves.

[7] The generic name is derived from the Greek words otos (ear) and anthos (flower).

This refers to the form of the corolla, which is composed of three membranous bracts that create a profile similar to that of a human ear.

The plant grows in the dune areas throughout the Mediterranean and exerts a stabilizing action on the sandy soils.
