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

Description

[edit]

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 cm (12 in) is formed. The dark green shoots are divided into 30 to 60 cm (12 to 24 in) long segments with a diameter of 7 to 10 cm (2.8 to 3.9 in), which are tapered at both ends. There are six to nine ribs, separated by deep incisions, that are 1.5 to 2.5 cm (0.59 to 0.98 in) 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 cm (0.79 to 3.94 in). The 15 to 25 spread radial spines are 5 to 25 mm (0.20 to 0.98 in) long.

The white flowers stand out horizontally. They are 7 to 9 cm (2.8 to 3.5 in) long and have a diameter of 4 to 5 cm (1.6 to 2.0 in). The egg-shaped fruits are initially green and later turn red. They are 5 to 9 cm (2.0 to 3.5 in) long.[3]

Distribution

[edit]

Armatocereus cartwrightianus is distributed on dry coastal plains in southern Ecuador and northern Peru.

[edit]

The first description as Lemaireocereus cartwrightianus by Nathaniel Lord Britton and Joseph Nelson Rose was published in 1920.[4] Arthur William Hill placed the species in the genus Armatocereus in 1938. Other nomenclature synonyms include Cereus cartwrightianus (Britton & Rose) Werderm. (1931) and Armatocereus cartwrightianus Backeb. (1936)
