Opuntia robusta, Wheel Cactus or Camuesa, is a species of cactus in the Cactaceae family.[1] It is native and endemic to Mexico, North America.


Plants are commonly around 1 metre high, though they may grow to over 3 metres-9 feet high when supported.[2]

The flattened stem segments are fleshy, round and blue-grey in colour.[2] These are up to 30 cm in diameter and have sharp spines up to 5 cm in length.[2] Yellow, sessile flowers with a fleshy base are produced on the edges of the upper stem segments.[2] These are followed by barrel-shaped fleshy fruits which are pink or purple and up to 8 cm long.[2]


The species was first formally described in 1837 in Enumeratio Diagnostica Cactearum hucusque Cognitarum.[1] It has naturalised in the states of South Australia, New South Wales and Victoria in Australia.[1]
