Description
Etymology: For Andrew Carnegie, an American industrialist.
The single species in this monotypic genus is certainly the most widely recognized and stereotypical cactus of all. The large Saguaro is a symbol of the desert Southwest and has symbolized the west in general in cartoons, on post cards, book covers, paintings, sculptures, etc. Because of this, many people associate the large, branched cacti with the west, however, in reality these quintessential cacti occur in the U.S. only in central/southern Arizona and a tiny bit into California on the Arizona border. This is quite the opposite of the widespread occurence many people romatically incorporate with thier impression of the Wild West. None-the-less, anyone who has stood beneath these magnificent giants can easily see the reason for their popularity. Cacti are foreign enough to the majority of the world with their leafless, succulent, spiny bodies; but add to that heights in excess of 50 feet and monstrous branches and the result is quite awe-inspiring and more than enough to fuel endless fokelore and tall tales.
