The authors have not seen any specimen of this species. Stewart (in Ann. Cat. Vasc. Pl. W. Pak. Kashm.) and Yuncker (in Flora Iran.) have cited Kent. 2079, a specimen from Chitral, Kalash as Cuscuta lupuliformis var. osiatica Engeim. The circumscription of the species is based mainly on Yuncker’s description.
