Thorns, Spines and Prickles

If you’ve ever hiked in the desert, discount viagra  you know that you have to watch where you walk.  Our desert is beautiful but it comes with some hazards.  Most desert plants and trees protect themselves with thorns, spines or prickles.  They’ve developed these as a way to survive in our oftentimes harsh environment.

I love the desert and I spend a lot of my time outdoors for my business and for my leisure time.  And, even when I’m very careful, I’ve been stuck by tree thorns or cactus spines.  Sometimes, you just can’t get out of their way.  This is why I usually wear long sleeved shirts, pants, and boots.  The more you’re covered, the less likely you are to get hurt.

Did you know there is a difference between thorns,spines and prickles? Thorns are modified branches and  stems. Spines are modified leaves. And, prickles are extensions a plant’s epidermis – like hairs.

You find thorns on trees such as the ones on mesquite trees.  Spines or glochids are the small hairy fuzz found on some cactus.  And, prickles are what you find on roses.  Thorns and prickles are much easier to remove from your skin than spines.  Spines are hard to see and often embed themselves in your skin to a point where you know they’re there but can’t remove them.  They eventually work their way out of your skin but it can take awhile.  Your best line of defense is to keep far enough away from thorny, spiny, and prickly plants that you don’t get stuck by them.  Next would be to keep hand sanitizer and tweezers with you when you hike.
