Whatever it is, it's absolutely gorgeous!
Sorry, this is kind of sidebar, but it looks like this is a Philodendron with a geniculum on the petiole? I'd read on Exotic Rainforest in the past that Philodendron (as a genus) doesn't have a geniculum, but was informed in another discussion that some Philos do have a geniculum and that the presence or absence of that feature can't be used to automatically include or eliminate Philo when trying to ID a mystery plant.
It's not always easy to know if one is seeing a geniculum or not, in pics. I'm trying to learn more about recognizing them, and what plants might have that. What are folks' thoughts about whether or not the reddish and slightly swollen area on the petioles of the plant shown here is a geniculum? TIA!
