So is your question about how to grow Tolumnias in general, or specifically these? You have been given some great advice about the general nature of Tolumnias and one post about the sylvestris (sp?). Just curious. If you are looking for specifics, then I would look to the Baker's website, orchidculture.com, and buy their species sheets for them (if they are indeed species). They have the best information on culture available for the species that were known at that time. They do not do hybrid information though.
