Paphiopedilum Marmorophyllum is (hookerae x barbatum). The plant stays quite small, but puts up a pretty tall spike with an impressive flower. The flowers are more burgundy/purple than the one shown, which is hookerae. We have been very impressed with the ones we have bloomed out so far, although I never got around to taking a photograph!
These are vigorous and easy to grow. Great for limited space and growing under lights.
