Very interesting species, the flowers have white lips and creamy petals and sepals. The floral stem produces a profusion of keikis. If you let them on the plant, the keikis produce new keikis and the new keikis more keikis and so on! The keikis weight end up bending the floral stem over and eventually the keikis attach to a branch or rock becoming independent plants. It is an interesting multiplication strategy also seen in other orchid species.
