Boojum Tree

The boojum or (Spanish) cirio (Fouquieria columnaris, syn. Idria columnaris) is a tree in the family Fouquieriaceae, whose other members include the ocotillos. It is nearly endemic to the Baja California Peninsula, with only a small population in the Sierra Bacha of Sonora.

The plant's English name was given by Godfrey Sykes of the Desert Botanical Laboratory in Tucson, Arizona and is taken from Lewis Carroll's poem "The Hunting of the Snark".[1]

The trunk of boojum tree is up to 24 cm thick, with branches sticking out at right angles, all covered with small leaves 1.5-4 cm long. They can grow to a height of 20 m. The flowers bloom in summer and autumn; they occur in short racemes, and are creamy yellow with a honey scent.
