Van Dieman Quality Bulbs put on a commercial display, featuring another example of L. lankongense, and Lankon, among others:

Not the greatest pics, but a couple of the darker Lankon stand out. I didn't see the lighter variant, but apparantly Van Dieman have them, and they're a better flower than the others.
Completing the display, three orientals from Van Dieman (colour representation doesn't do the first one any justice - it's much cleaner than portrayed):
