[Wikipedia] Taxonomy: Previous treatments of the species divided it into three varieties. In 2009, two of them were combined into a separate species called Cuscuta pacifica.[1] The two species can easily be differentiated by habitat geography: the varieties of Cuscuta pacifica grow solely in coastal habitats while Cuscuta salina sensu stricto grows inland in alkaline or saline seasonally wet habitats such as vernal pools and salt flats, such as the margins of the Great Salt Lake.
