From the Wikipedia:
The Saguaro, pronounced "sah-wah-roh", (Carnegiea gigantea) is a large, tree-sized cactus species in the monotypic genus Carnegiea. It is native to the Sonoran Desert in Arizona and California, United States and northern Mexico.

The common name of the cactus, saguaro, is a Spanish-language adaptation of a word used by a local aboriginal American nation, the Tohono O'odham, for the plant. Local English speakers pronounce it /səˈwɑɹo/.

Saguaros are slow growing, taking up to 75 years to develop a side arm. The arms themselves are grown to increase the plants reproductive capacity (more apices equal more flowers and fruit). The growth rate of saguaros is strongly dependent on local precipitation patterns ...

Ocotillo, photos of ...

February 2008, KOFA National Wildlife Refuge - there seemed to be more downed Ocotillos lying around on this visit to the KOFA.

From the Wikipedia: The ocotillo (Fouquieria splendens - also called the coachwhip, Jacob's staff, and the vine cactus) is a curious, and unique desert plant of the southwestern United States and northern Mexico. For much of the year, the plant appears to be an arrangement of large spiny dead sticks, although closer examination reveals that the stems are partly green. With rainfall the plant quickly becomes lush with small (2-4 cm) ovate leaves, which may remain for weeks or even months.

Desert varnish ...

The dark color of the rocks in the following picture is caused by desert varnish. The light color that looks like someone swiped a paint brush across the rock is the actual color of the rock (or at least closer to it). The lighter color was hidden until the rock was repositioned by human, animal or weather.
