Draining the swamp dodders: Systematics of Cuscuta gronovii s.l. (subgenus Grammica, sect. Oxycarpae)

Cuscuta gronovii species complex (sensu lato, s.l.) is a North American group of species that belong to sect. Oxycarpae of subgenus Grammica. Members of C. gronovii s.l. are often associated with riparian or wet habitats, and their delimitation has been problematic historically. DNA sequences from multiple plastid and nuclear ribosomal non-coding regions were used to reconstruct evolutionary relationships among taxa. Molecular phylogeny supported the resurrection of C. saururi, a taxon that has been treated either as C. gronovii var. latiflora or a nomenclatural synonym of C. gronovii var. gronovii. Cuscuta saururi was inferred to be sister to C. cephalanthi, but the relationships among the rest of taxa, although forming a clade with a moderate support, remained largely unresolved. Thus, the species limits of C. gronovii s.l. aggregate were also comprehensively investigated through a morphometric study. Plants with 4-merous flowers from New Brunswick and Nova Scotia, Canada, which were ..., The dataset consists of 47 characters measured or scored from rehydrated and dissected flowers, fruits and seeds of seven Cuscuta taxa. 200 herbarium specimens deposited in different herbaria from North America were used for this purpose (For full details of the specimens see Appendix 1 in the article).
