--><p>Plants of Waldsteinia are distinctive, small, rhizomatous, and often mat-forming herbs of woodlands with ternate or three- to five-lobed leaves, differing from Geum by their long, straight, deciduous styles. J. E. E. Smedmark (2006) showed that the type species of Waldsteinia is nested in Geum.</p>
