Tulip but not a poplar, it actually has no relation to the poplar family. If I remember right it’s closest relationship is to the cucumber tree which includes magnolias.
true. but it has been "poplar" in common usage for a LOOOONG time.
and one source has Liriodendron as meaning "lily tree".
another source has it as "lyre-tree".
so; it's either "lily tree, tulip-bearing", or "lyre-tree, tulip-bearing".
