Cirrhopetalum frostii

I do not grow a lot of Cirrhopetalums or Bulbophyllums, but this is one I have had for many years and it  finally bloomed for me this spring.  It is an attractive plant with fat 2 cm oval pseudobulbs closely spaced along a thick rhizome and  4 cm oval leaves.  The short flower spike comes from the base of the pseudobulb and has two or three flowers, 3 cm in size, that are often compared to a Dutch wooden shoe or a slipper.
