Taxonomy

Erythranthe nudata is a member of the Erythranthe guttata species complex, a group of closely related wildflower species that vary dramatically in mating system, life history and edaphic tolerance.^[7] Species in the E. guttata complex are largely inter-fertile, with some notable exceptions. In particular, E. nudata is reproductively isolated from other complex members via a postzygotic isolating barrier during seed development.^[8]
