Description

Armatocereus matucanensis grows like a tree, branches out from the base in particular and reaches heights of growth of up to 6 metres. A strong trunk is usually formed. The upright, often lump-forming, grey-green, bluish-tinted shoots are divided into 30 to 50 centimeter long segments with a diameter of 7 to 13 centimeters. There are five to eight ribs separated by shallow furrows. The primrose, angular, flattened and slightly twisted brown spines later turn gray and have a darker tip. The one to four central spines have a length of three to seven centimeters. The 8 to 14 spread radial spines are 5 to 15 millimeters long.

The narrow, funnel-shaped, white flowers stand out horizontally or are erect. They are up to 10 centimeters long and have a diameter of 6 centimeters. The ovoid fruits are green. They are 8 to 13 centimeters long.[3]

Distribution

Armatocereus matucanensis is found in Ecuador in the province of Loja and the Peruvian region of Lima.
