Argentina
HillPerennial (in Australia), soft or semi-woody herbs, prostate to decumbent. Leaves cauline, pinnate; leaflets toothed to dissected; stipules ventrally attached and largely fused to petiole with free wings that meet at their bases. Inflorescence a cyme or flowers solitary. 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.
About 65 species, mainly Himalayan Asia, also New Guinea and New Zealand; 1 species in Australia. 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.
