Cuscuta campestris—host plant relationship. a Cuscuta campestris (yellow) infecting Pelargonium zonale. b Close-up of a parasitic vine entwining and infecting a host shoot. c Cross section through an infection site. The right half of the micrograph was overlayed with color to emphasize the border between C. campestris (yellow) and the P. zonale stem (green). d Simplified phylogenetic tree of reported host plant species of C. campestris, showing the variety of angiosperm orders (named on the right) that contain host species (according to refs. 1,2,3). The gray background highlights the single described monocot host. The asterisk indicates the closest phylogenetic relative of C. campestris (Convolvulaceae) within the host groups
