Saguaro cactus

Of course, anyone who is allergic to bee or insect stings should consult a doctor for treatment if stung. Hikers subject to severe reactions should carry antihistamines and an anti-sting kit.

CACTUS AND OTHER INTERESTING PLANTS

Cactus is found throughout the state, though only the Sonoran Desert of southwestern Arizona has the well-known giant saguaro cactus. Most cacti grow in isolated patches and are easily avoided. The cholla cactus propagates itself by growing easily dislodged joints. The long, sharp spines have invisible barbs, so the joints cling tenaciously and are difficult to remove. Use a comb, or a pair of sticks, to pop them off the skin or clothing. Carry a pair of needlepoint tweezers to remove hard to see spines. Cactus spines are a serious hazard to air-filled sleeping pads, and they’re often sharp enough to go right through a tent floor or groundsheet. Look the ground over very carefully before setting up your shelter. In poor light, it helps to sweep the ground with a light beam parallel to the ground.
