Oldest boojum tree in US is dying, to be cut down
The University of Arizona plans to remove a boojum tree (Fouquieria columnaris, Foqueriaceae) from its arboretum after discovering that the tree is diseased and dying. The tree failed to leaf out this year and the stem was seriously decayed. The tree is not only the oldest boojum in the US, but the largest in Arizona. Boojum is a strange stem-succulent tree of the Baja California desert. The common name, given by its discoverer Godfrey Sikes, is a joking reference to the boojum of Lewis Carroll's The Hunting of the Snark.

Boojum is a bizarre plant, which barely meets the definition of a tree. It forms forests of scattered individuals in Baja California and adjacent Sonora. An interesting description with good pictures can be found at the Desert Ecology site. The University of Arizona has a good description if its specimens at its Arboretum site.
