Near Cuscuta chinensis LAM., but differs from it by the much broader sepals 

 and corolla-lobes, and in the much shorter corolla-tubes. Here is a plant called 

 Cuscuta Grasii DELPONTE in Hongkong, with which species our plant should 

 be compared. The original description of C. Grasii is not accessible to me.
