Hypanthium shallow, weakly concave; epicalyx lobes 5, similar to and alternating with the 5 sepals; petals usually 5; stamens 10–30; ovary superior, carpels 10–80, ovules 1 per carpel, styles surrounded by hypanthium rim. Fruit a head of 4-many achenes on surface of dry or spongy hypanthium.

Very closely related to Potentilla with only the stipular character offering reliable morphological separation, although genetic studies show it to form a distinct group distinct from Potentilla sens. str.
