Description

The sand Cinquefoil differs from Spring cinquefoil ( Potentilla neumanniana ), which it is very similar otherwise. Due to the dense pubescence with many-rayed stellate hairs The lower leaf surface is very densely tomentose stellate hairs and thus colored light gray green on top of the hair is a little less dense. Can not always be strictly separated from each other but both types, because there something called Intermediärformen. In addition, it is not uncommon to x subarenaria Bastardisierungen of Potentilla Potentilla arenaria and neumanniana = Potentilla.

The sand cinquefoil is a perennial herbaceous plant that reaches the stature heights of 5 to 15 cm. There are gebildendt lawn like stocks, but without stolon -like rhizomes extended. The stems and especially the underside of the leaves are more or less densely covered with 15 to 25 (6 to 35) - rayed stellate hairs and also with small, bright glands.
