How accurate are cactus pictures?

Cactus pictures are usually accurate when it comes to displaying the plant and its various structures; however, pictures can be mislabeled as cacti when in reality the subject of the picture is classified as a succulent and not a cactus.

When viewing a picture that claims to be of a cactus, examine the visible plant structures in the picture and consider any extra information provided, such as the origin of the plant. Structures such as the flowers, the leaves and the spine can help determine whether or not the plant is a cactus or a succulent. Many succulents can share characteristics with cacti, so consult an expert if an image is vague.
