Sunny

Casting a spot of brightness on a bleak winter season.

Sallow

Closeup of Saguaro with unusual patches of yellow bark.

All Yellow

Continuing a series of cactus variants: The pigment of this young Saguaro appears to be a bit off, with large patches of yellow. Closeup tomorrow.

Ripple effect

Closeup of red hook cactus with strange bulges.

Misshapen

Something must have happened with water supply, insects or disease to cause the unusual rippling of this red hook cactus. Closeup tomorrow.

Burnt out

The remains of this barrel cactus are blackened as though burned. No flesh remains, but this may only be the way this cactus decays in the dry desert heat.

Fluffy

The "spines" of the Hairy Sentium cactus appear benign when compared to those of its cousins.
