cactus

This tag should used when a cactus is visible in the image, regardless of it being planted on the ground or on a plant pot.

Cacti (cactaceae) are plants often found in arid environments, usually deserts. Cacti occur in a wide range of shapes and sizes. Most cacti live in habitats subject to at least some drought.

Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. In the absence of leaves, enlarged stems carry out photosynthesis.
