Have either of you tried floating a leaf or keeping the base of the petiole submerged?

Using the african violet analogy, you can either root them in a substrate after dusting them with rooting powder, or just stick the petiole in a glass of water and plantlets form at the base either way.

Cheers.

When you think about it, C. ciliata does it. New plantlets grow out of the leaf axils to a certain size and then stop. Don't know if they're attached to the petiole. I've snapped them off, potted them up, and they merrily grew away.

Ironically, Jan showed me a ciliata he has that produces runners instead of plantlets in the axils.

Cheers.
