A late friend went to Kirstenbosch about 6-8 years ago and bought seeds there. She gave several of us seedlings and the first has just flowered with a friend but she can’t identifiy it. She says: "It didn't have a label so guessing from caulescens, gardenii or nobilis groups, Possibly a cross." Hard to tell anything about the mouth of the flower other than pinched.Wonder if maybe you can help?
