I find it a very nice sublaeve, you have there - nice, harmonious form, well proportioned, good stance and good colours! The plant itself looks great, too, and really thriving. Keep up the good growing - and you will soon have a gorgeous specimen plant at hand!

What differentiates 'var sublaeve' from other forms of callosum? I think mine that is in bud, and is also bi-floral, is the same as this but it is just labeled as Paph. callosum. Nice flat dorsal, by the way.
they are overall smaller plants with smaller flowers. To me, the patterns on the leaves are also different but that can be highly variable from plants to plants. The same goes for the flower shape. Also, it tends to form a clump readily compared to typical callosum.
