This is Raphia regalis, a Central African tree which has the world's largest leaves.
It's a type of palm tree (which makes it a monocot), with pinnate leaves growing up to 26 metres long. The leaf blade makes up 16 metres of that length.
@InvaderXan This is amazing—they're like bushes that have been scaled up!
@ErikaAlpert
That is *exactly* what I thought when I first saw them!
@InvaderXan They're so big and precious, I love them.
