The yellow to yellowish green flowers are up to 3 centimeters long. The top-shaped to club-shaped, red fruits are fleshy and usually not thorny. They are usually sterile and have conspicuous humps.
Distribution, systematics and endangerment
Cylindropuntia tunicata is distributed in northern to central Mexico and possibly in the United States in the state of Texas in the vegetation of the Chihuahua Desert at altitudes of 100 to 1900 meters. Its distribution area also extends over the states of Ecuador , Peru , Argentina and Chile . These occurrences in South America are possibly due to the carry-over of shoot sections by humans or cattle.
