Description
Summary:•In North America, cattails are invasive where they hybridize extensively.•We used microsatellite data to genotype cattail species and hybrids in Europe.•Hybrids in Europe are rare, which may help explain why cattails are not invasive there.•We found multiple genetic lineages in T. angustifolia and T. laxmannii.•Managers should monitor future potential hybridization among lineages and species. Cattails (Typha spp.) are essential components of wetland around the world, although they can also be problematic invaders. In some regions of North America, T. latifolia and T. angustifolia hybridize to produce T. x glauca, which is invading and dominating wetlands around the Laurentian Great Lakes. However, in other regions such as China and the maritime provinces of Canada, hybrids are either non-existent or maintained at very low frequencies, and cattails are not considered invasive. Little is known about cattail hybrids in Europe. We used microsatellite markers to characterize T. latifolia, T. angustifolia, T. laxmannii, and T. domingensis sampled from 63 sites across nine European countries. Hybrids were very uncommon (
