Cacti - No Succulents

Brief

In this contest, I would like to see your photos of cacti. Flowering cacti are welcome, but please also include some of the plant. Please submit photos of individual plants only, no garden or desert scenes with cacti. Please no photos of succulents, only cacti. Remember, cacti have areoles at the base of their spines which are discs with tiny spines; succulents do not. Other plants including succulents may be background plants but the main focus of the photo must be a cactus plant.
