Description edit

Cereus hexagonus grows like a tree with erect shoots that branch out from near the base and can reach heights of growth of up to 15 metres. The cylindrical, segmented, glaucous light green shoots have a diameter of up to 12 centimeters and more. There are four to seven thin, wavy ribs that are 3 to 5 centimeters high. The areoles on it are small. The thorns are missing on young shoots or there are only a few. Older shoots have 8 to 10 or more unequal spines per areole. The initially brown thorns become lighter later. They are 5 to 6 centimeters long.

The white flowers are 20 to 25 centimeters long. The 5.5 to 13 centimeters long, egg-shaped fruits are light red. They contain white or pink flesh.

Distribution edit

Cereus hexagonus is distributed in Guyana, French Guiana, Suriname and Venezuela.

The species is classified as Least Concern (LC) in the IUCN Red List of Threatened Species.[1]

Taxonomy edit

The first description as Cactus hexagonus was published in 1753 by Linnaeus in his work Species Plantarum.[3] Philip Miller placed the species in the genus Cereus in 1768.
