Not sure how fruitful your search will be, especially if you're after
the Asian species. Outside of Australia and New Zealand, there aren't a
lot of people growing them (and Aussies and Kiwis only grow their
native species). It may be worth asking for sources over at the
terrestrial orchid forum: http://terrorchid.proboards27.com
