Paphiopedilum
     (primulinum x gardineri) [gardineri aka glanduliferum var. wilhelminae]
This is an interesting (and yet unregistered) hybrid. It’s a cross between primulinum (yellow flowers, sequential bloomer) and gardineri/glanduliferum var. wilhelminae (striking mahogany and white dorsal sepal and deep colored, twisting petals). They’ve been good bloomers.
