species - Taiwan
These plants are mounted on virgin cork pieces (OK, "virgin" cork is cork harvested before the cork oak tree is mature enough to produce cork suitable for wine bottles) and can best be treated like a mounted Phalaenopsis. That is, keep the roots moist, fertilize regularly, give the plant bright indirect light and night temperatures of 60 degrees or so.
Flower are about 3/8" across, produced few to many on semi-pendant stems, mostly in Winter and have a very nice floral fragrance. Our plants are about 5" across and are near flowering size.
