Everybody knows saguaro cactuses have arms. The classic cartoon version has two symmetrical ones; real ones typically sport up to a half-dozen or so. But occasionally, some kind of genetic defect causes a cactus to sprout arms like crazy! Here are a few especially odd ones that I have come across in my travels in the Arizona desert.
Thanks to Rick Scott for giving me directions to this giant; he counted at least 62 arms.  Rick also estimated the height at 39 feet -- very tall but not a record-holder (see my mountain bike for scale).
Directions: Near Florence Junction, within the Desert Wells Multiuse Area; just off of Route # 26, approximately 1/4 mile southwest of the intersection of Routes # 1 and 2.  GPS coordinates for the saguaro: 33d 15.282m, 111d 26.576m.  Warning: The cactus is several miles away from the paved road; do not attempt to locate it unless you have a well-equipped, high-clearance four-wheel-drive vehicle, the Desert Wells Multiuse Area map, a State Trust Land permit (required), and good route-finding skills or a GPS unit.

I didn't notice this cactus at the time I took the photo; I discovered it later while looking at the telephoto image of hundreds of saguaros on a distant hillside.
Directions: Hog Canyon is a rough off-trail hike in the Superstition Wilderness; the trailhead is one mile west of the Hieroglyphic Spring Trailhead.  The hillside with the cactus is on the left as the wash enters the canyon.

I'm not sure if this is a saguaro or a related variety of cactus, but its tightly-clustered multiple arms caught my eye as I was driving by.
Directions: In the front yard of a private residence.

Likewise, I'm not sure if this is technically a saguaro, but it's sprouting countless ball-shaped arms.

This is not a saguaro, but a cardón, a close relative of the saguaro that is native to Mexico.
Directions: In the front yard of a private residence.
