Hybrid Avens - Geum rivale x urbanum = G. x intermedium

    Description

    Hybrid Avens is a hybrid of Wood Avens (Geum urbanum) with Water Avens (Geum rivale). This fully fertile hybrid can be plentiful where the parents meet, and the resulting hybrids can exhibit a full spectrum of intermediate forms between the two parents covering every aspect. It usually has drooping yellow flowers and five sepals with a shorter, narrower bract between the sepals. A ring of stamens with yellow anthers surrounds a bunch of green stigmas.
