Crested Cactuses

The tall, columnar shape of the saguaro cactus is familiar to any desert traveler. But very rarely (perhaps only one plant in 100,000), a saguaro will grow with a fan-shaped crest of uncontrolled growth at the tip. These oddities of the plant kingdom are known as cristate (or crested) saguaros. The deformity also occurs in other species of cactus, such as the organ pipe. Science has not yet fully explained why this mutation occurs; perhaps it is caused by frost damage, although many other explanations have been offered. Whatever the cause, I find the swirling shapes strangely beautiful; here are photos of some of the crested cactuses I have come across in my desert travels.
