Armatocereus matucanensis is a species of Armatocereus from Ecuador and Peru.[2]

Description

[edit]

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 cm (12 to 20 in) long segments with a diameter of 7 to 13 cm (2.8 to 5.1 in). 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 mm (0.20 to 0.59 in) long.

The narrow, funnel-shaped, white flowers stand out horizontally or are erect. They are up to 10 cm (3.9 in) long and have a diameter of 6 cm (2.4 in). The ovoid fruits are green. They are 8 to 13 cm (3.1 to 5.1 in) long.[3]
