Xiquexique is genus of cactus from Brazil .[1]
Description
The Xiquexique genus comprises cacti that range from columnar to shrubby in shape. Their main stems grow upright, often with arched branches that run parallel to the ground. These stems typically have 4-15 ribs, and their fruits commonly display floral remnants that stand erect rather than being sunken into the apex of the pericarp. This morphological distinction from Pilosocereus is characterized by Xiquexique's candelabra-like branching stems, sinuated ribs, and the absence of sunken floral remnants on the fruit pericarp.[2]

Taxonomy
The genus Pilosocereus into two subgenera in 1994 by Zappi, one of them being Pilosocereus subg. Gounellea based on its candelabra-like branching stems. In 2020, a phylogenetic analysis by Lavor, Calvente, and Versieux led to the elevation of the subgenus to its own genus, named Xiquexique. This new genus was named after the common name of Pilosocereus gounellei, which is known as the xique-xique in Brazil.[2]
