Dig deeper at SERNEC, a consortium of southeastern herbaria.

Nesom (2021) described several new species of Tiarella, and thus redefined the range and characters of this original Tiarella species. Read more at Vascular Plants of North Carolina.

Nesom's (2021a) analysis demonstrates that the typic component of Tiarella cordifolia must represent the non-stoloniferous taxon present in eastern Virginia, contrary to the misapplication by previous authors. Read more in Weakley's Flora.

Five species of Tiarella are present in the eastern United States! The main features distinguishing them are presence/absence of stolons, shape of the basal leaves, and presence/absence of leaves on the flowering stem. When the plants are sorted by these physical characters, the five entities are remarkably consistent in geography, showing sharp boundaries with very little overlap. Each of the five tiarellas fits the generally understood definition of “species” – a population system distinct in appearance from others and genetically discrete, forming few or no hybrids with other population systems.
