Strophocactus sicariguensis, synonym Pseudoacanthocereus sicariguensis, is a species of plant in the family Cactaceae. It is native to Colombia and Venezuela. It has often sprawling thin stems and white funnel-shaped flowers that open at night.
Description
Strophocactus sicariguensis grows as a shrub, initially upright and later sprawling. It branches freely from the base. The thin stems are up to 2 m (6 ft 7 in) long and 3 cm (1.2 in) across and have 2–5 ribs bearing areoles with spines up to 2 cm (0.8 in) long. The white funnel-shaped flowers open at night and are up to 16 cm (6.3 in) long.[4]
Taxonomy
Strophocactus sicariguensis was first described, as Acanthocereus sicariguensis, in 1947.[1] It was transferred to the genus Pseudoacanthocereus as Pseudoacanthocereus sicariguensis by Nigel P. Taylor in 1992,[5] a placement still accepted by some sources (As of February 2021).[2] A molecular phylogenetic study of the Hylocereeae by Korotkova et al. published in 2017 showed that Pseudoacanthocereus sicariguensis formed a clade with Strophocactus wittii and Pseudoacanthocereus brasiliensis (the only other species placed in Pseudoacanthocereus):[3]

Accordingly, both species of Pseudoacanthocereus were transferred to Strophocactus.[3]
Distribution
Strophocactus sicariguensis is native to Colombia and Venezuela,[2] in particular around the Maracaibo Basin.[3]
