John, those are nice looking Pinanga's, good size too.
Here are a few pics of P. maculate, at least that was what I acquired them as. Good growers and really colorful. I think mine get a tad too much sun, but
none the less are still pretty nice. The leaf is a dark green with visible mottling. Would probably be more pronounced if they were in more shade.
A few adventitious, but no stilt roots. The larger one has been in the ground almost 3 years and the other about 2.
