Very common among heather and in grassland.

Flower diameter c 7-12 mm

Skye ID: Most of its flowers have 4 petals.  Other Potentilla species have 5.  Tormentil flowers with 5 petals are frequently found but seem to be random and any given plant will normally have 4 on most flowers.

Other features: A low-growing plant.  Most leaves have three leaflets plus two large stipules at base looking like leaflets.  Basal leaves long-stalked, occasionally with 5 leaflets but most have 3.  Alpine Cinquefoil and Creeping Cinquefoil have 5 leaflets as the norm for base leaves.  Flower stems do not root.  Stem-leaves almost unstalked, which is why the stipules look like part of the leaf.  This does not occur with the other two species.
