I was shocked to learn that the autumn crocus isn't a crocus.
It reminds me of when I was in Patagonia. There's a tree/shrub which looks like a beech tree (fagus), so it was included in the fagaceae family. When it was discovered that it was genetically distinct from other trees of that family, a new family was created whose members are called nothafagus (not-a-fagus), Nothofagus antarctica being the one you'll most likely come across in southern Chile. The most southerly tree on earth is a nothafagus.
