You have a rare orchid there. Been looking for one for a long time but unsuccessful so far. It used to be classifidied as an Ascocentrum and although it is supposed to originate from our region it is a lucky hobbyist who can find one here in the nurseries. It is a vandaceous so culture for vandas apply. Your colour form seems to be darker than the norm.Thanks for posting.Is it possible to take clearer pictures of it?
