Discussion | Cuscuta coryli is closely related to C. indecora, from which it differs by often relatively small, four-merous flowers, bifid infrastaminal scales with one to three fimbriae on each side of filament attachment or with denticulate wings, and depressed capsules (M. Costea et al. 2006). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
