Joe here again with another tiny orchid, Adenoncos parviflora. This little thing comes from South East Asia and Malaysia where it grows in low montane and hill forest and so we grow it in Warm Asia.
The flower is tiny but very attractive as long as you have good eye sight or a macro lens. We guess it must be pollinated by a gnat or a tiny ant as it is close to the stem.
We grow this species on a small piece of cork bark as you can see in the photo. This shows the plant off in a natural way and stops it getting smothered by moss. We spray it with water once a day.
