INFORMATION ABOUT THE OCOTILLO FROM Adventuring in the California Desert by Lynne Foster.
This 10-ft shrub with its bright red flowers does most of its branching from its base, which gives it a characteristic shape. The ocotillo we see in the California desert (Fouquieria splendens) has somewhat translucent, scaly bark and produces a fruit that at maturity opens into a three-valved capsule and releases its seeds. When the shrub is growing and elongating at each node, it has normal-looking leaves. These leaves are relatively short-lived; they fall as the soil dries out and water becomes unavailable. Surprisingly, though, the leaf stem and part of the midrib do not drop, but take on the appearance of a large, rigid, slightly curved spine.
When the ocotillo is not growing, soaking rains prompt the production of delicate, bright green leaves in just a few days, particularly in warm weather. These leaves fall from the plant when the earth again dries out. This cycle of leaf production and falling can be as short as a month. Unlike the primary leaves, all that is left after these secondary leaves fall is a minute scar.
This ocotillo is a Colorado Desert species that ranges into Baja California. There are several related species in Baja that, although somewhat different from the species found in the California desert, are readily recognizable as being of the ocotillo family (Fouquieriaceae).

The Ocotillo (oh-koh-TEE-yo) is a NOTHIN'. You'll hear it called a "Monkey Tail Cactus" but it's not a cactus. And it's not a lily. It's not closely related to any other plant of the Southwest desert. South of California, in old Mexico, it has one kin, the Boogum Tree, which is an even stranger plant. These two belong to a scanty family which the botany boys (in desperation) named "Fouquieriaceae"-- whatever that means. To ordinary folks the Ocotillo has more aliases than a check artist. Besides "monkey tail" it is known as "candlewood", "coach whip", "Jacob's staff", etc.
