I'm preparing a new entry in my blog with a short text about Phragmipedium Sedenii (Cypripedium Sedenii), a plant I got recently as a surprise birthday present. I've always known - don't ask me where I read it some 30 years ago! - that Sedenii is also a natural hybrid (x sedenii); now I've been researching and I just don't find a prove of this, though many pages repeat that it is a natural hybrid, there are no references to the original description (Reichenbach fil, Rolfe, Schlechter)! There is also little info about John Seden besides wiki and Hortus Veitchii; does anybody know where I can find a photograph and some further details about the 'father' of Phrag. Sedenii? Thanks!
