Cactus

Cactus is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word cactus derives, through Latin, from the Ancient Greek word κάκτος, a name originally used by Theophrastus for a spiny plant whose identity is now not certain.
