This dramatic and unusual species was shown as a foliage plant at the 1998 AGGS Convention, under the name P. duclouxii. The species is quite small, producing mature plants on the order of 4 inches across.
It does produce large well-formed flowers, held well above the foliage, as can be seen by clicking here or here. A close-up of the flower can be seen here. This whole foliage plant can be seen by clicking here.
Note the pronounced spiral pattern produced by the leaf placement, and the very flat tiled effect of the leaves.
