I just ran a search again at C.O.T.W. I kept my search very simple. I only told it to search for white tepals in July. Clematis recta & a lot of others were on the long list. http://www.clematis.hull.ac.uk/new-clemlist.cfm You can make your searches very specific or keep them general to open up the possibility of various varieties.

Be very glad that 'Sweet Autumn Clematis' didn't return on its own! I can't seem to kill all the seedlings that keep popping up all over my garden, year after year! Believe me when I say, I don't baby it (never have), don't water it (except what it gets from Mother Nature), never gave it any winter protection and no full direct sun. It grows (or grew) along the North side of my split rail fence at least 15-20ft. Then it proceeded to climb the 'Sky Rocket' Junipers and my Holly tree. Talk about invasive! It's a THUG! Gardeners BEWARE especially in the warm growing zones!!!
