Yetman IV


Here’s the 4th and final picture “borrowed” from the Arizona Daily Star‘s article about David Yetman’s new book, “The Great Cacti: Ethnobotany and Biogeography.”

“This is probably the easiest of all columnar cacti to identify just because it has this extraordinary cephalium (a brightly colored structure of wool and bristle at the growing tip of certain cacti). . . . It only grows in one small area, not even as big as Pima County, in Mexico. . . . What’s extraordinary about this, not just the appearance, those cephalia look as though they’re layered (coffee) drinks. . . . They have been wildly exploited because cactus collectors like them.”
