Cacti form a single, closely related family, known as Cactaceae. It lies within the broader group of succulents, while maintaining its own distinct identity. Our list of cactus species covers the entire family.
Botanists estimate there are approximately 1,750 species, distributed across approximately 130 genera, and almost all of them are native to the Americas. The only odd exception is Rhipsalis baccifera, which also grows wild in parts of Africa and Sri Lanka. Its seeds were likely carried there by birds or old sailors, while all other cacti are firmly rooted in the Western Hemisphere.
A single structure distinguishes cacti from all other succulents. Areoles are tiny raised pads located throughout the plant from which spines, flowers, and new shoots emerge. No other plant family produces such small cushions. The spines themselves are actually leaves, cleverly disguised as regular ones, as regular, broad leaves would waste too much precious water. The stem turns green and quietly performs photosynthesis — a trick unique to the Cactaceae family.
Not every cactus is a desert survivor, despite popular belief. A whole group of cacti actually lives high among humid tropical trees, growing as epiphytes directly on the branches. Their appearance and habits are starkly different from the spiny desert species we all imagine. You can compare the two sides in the table below.
Type | Habitat | Morphology | Examples |
Arid, sunbaked ground | Thick stems, heavy spines | ||
Humid tropical canopy | Flat or trailing, few spines | Christmas cactus, Rhipsalis paradoxa |
