Top Voted Definition for #cactus
A cactus is a member of the plant family Cactaceae (order Caryophyllales). The word "cactus" derives from the Ancient Greek kaktos, a name originally used for a spiny plant whose identity is not certain. Cacti are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north—except for Rhipsalis baccifera, which also grows in Africa and Sri Lanka.
