Discussion

Species 6 or 7 (4 in the flora).

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.
