When I purchased my plant years ago it was Stephanotis floribunda but apparently the scientists changed it to genus Marsdenia.
The Catalogue of Life (last updated May, 2016) is showing Stephanotis floribunda as a synonym for Marsdenia floribunda as our database currently lists it.
Stephanotis floribunda Brongn. Species synonym for Marsdenia floribunda (Brongn.) Schltr.
