Dear Peter, 24 years ago I looked into this question and wrote a piece for the South African Orchid Journal - my first article published. I have scanned it and put it up on my website at http://www.geocities.com/pennypoint9/dendrob.html Have a look and pull it to bits. regards, greig russell "Valhalla", Osborne Lane, 7975 KOMMETJIE, Western Cape.
