Abstract

We report three rare dodders (Cuscuta L.) from Quebec: Buttonbush Dodder (Cuscuta cephalanthi Engelmann), Hazel Dodder (Cuscuta coryli Engelmann), and Smartweed Dodder (Cuscuta polygonorum Engelmann). Detailed descriptions of their morphological characteristics, ecology, and host range are discussed. The genus Cuscuta is severely under-collected in Quebec and elsewhere, and targetted fieldwork is needed to better assess the distribution and conservation status of the three rare (or overlooked) species reported here. An identification key to all Cuscuta species from Quebec is provided to aid botanists in accurately identifying these challenging species.
