Armatocereus cartwrightianus is a species of Armatocereus from Ecuador and Peru. [2]
Armatocereus cartwrightianus grows as a shrub or tree and reaches heights of up to 12 meters. Usually a well-developed trunk of up to 2 meters in height and a diameter of 30 centimeters is formed. The dark green shoots are divided into 30 to 60 centimeter long segments with a diameter of 7 to 10 centimeters, which are tapered at both ends. There are six to nine ribs, separated by deep incisions, that are 1.5 to 2.5 centimeters high. The needle-like, brown thorns later turn white and have a darker tip. The one to four central spines have a length of 2 to 10 centimeters. The 15 to 25 spread radial spines are 5 to 25 millimeters long.
The white flowers stand out horizontally. They are 7 to 9 centimeters long and have a diameter of 4 to 5 centimeters. The egg-shaped fruits are initially green and later turn red. They are 5 to 9 centimeters long. [3]
Armatocereus cartwrightianus is distributed on dry coastal plains in southern Ecuador and northern Peru.
