And thus I have a special fondness for the Boojum Tree at the Desert House of the Garfield Park Conservatory in Chicago. It's a crazy-looking tree endemic to the Baja Peninsula and state of Sonora in Mexico. Fouquieria (or Idria) columnaris is related to the ocotillo, a spiny plant familiar to anyone who has spent time in Arizona. I wouldn't say the Boojum is attractive, exactly, but it's rare and interesting and dangerous-looking and through the magic of conservatories it's growing right here in Chicago.
What does our intrepid hero, the Baker, have to say about it?
"But if ever I meet with a Boojum, that day,
In a moment (of this I am sure),
I shall softly and suddenly vanish away--
And the notion I cannot endure!"
Luckily for us, this Boojum is entirely non-lethal and does not cause involuntary vanishification.
The Baker unfortunately met with a less friendly instance of Boojumness...
In the midst of the word he was trying to say,
In the midst of his laughter and glee,
He had softly and suddenly vanished away---
For the Snark *was* a Boojum, you see.
