According to the database this is a synonym of Canistrum fragans. I could not find this connection in the CoL. As far as I could find the synonym for E. Lindenii is Canistrum lindenii (and others), but not C. fragans. C. fragans is now Hohenbergia augusta. So, I think, these two should be separated into E. lindenii and H. augusta.
To what I could find all pictures are E. lindenii, not Hohenbergia augusta.
