Genus: Geum — avens

To key species of Geum, use fresh material to assess petal color, since petals fade upon drying. Check sepal position before measuring petal length. Petals keep growing until sepals are fully reflexed, so measuring petal length on younger plants will result in an incorrect measurement. Species formerly placed in the genus Waldsteinia are placed in Geum in this key (Smedmark et al. 2003).
