This species is close to Cuscuta europaea, from which it is differentiated by having purple stems, sessile stamens and sepal lobes with reticulate venation and style 2.5-3 mm long. Different forms of this species described by Yuncker are not recognized here both because only a limited number of collections are available, and the characters used by Yuncker for the separation of different forms intergrade.
