There were several excellent examples of barrel cacti near the Saguaro National Park visitor center. Compare this one's variations across the spectrum with some of the other native cactus species.

A barrel cactus in bloom. The flowers' variation in UVA reflectivity (a simple bulls-eye pattern) is one of the most common in flowers of all types.

Large trees can grow in the desert, as long as they're provided with water :). Even so, it's interesting to see how in at least this case, the tree has created cloud-like webs of spindly branches to collect sunlight instead of large individual leaves or small, dense needles.

A close-up shot of the flowers on a barrel cactus. At this distance, the middle ring of the ultraviolet "bulls-eye" is revealed to be a vast number of dark stalks with bright tips, waving about in the wind to attract bees.
