Stenocereus heptagonus is a species of cactus. [2]

Description

Stenocereus heptagonus grows as a tree-like cactus with numerous candelabra-like branches, reaching heights of 8 to 12 meters. It forms a distinct trunk, and its upright to slightly spreading shoots can reach up to 30 centimeters in diameter. The cactus has 9–12 sharply defined ribs, each up to 1.5 centimeters high. Its spines include three gray central spines, one longer than the others, up to 4 centimeters long, and about ten grayish peripheral spines.

Contents

The flowers, which open at night, are 7–9 centimeters long, greenish to slightly purple on the outside, and white on the inside. Its spherical, red fruits are 5–6 centimeters in diameter, covered with spines that fall off when ripe. The pulp is red, and the seeds are black. [3]

Distribution

Stenocereus heptagonus is endemic to the West Indies, including the Greater Antilles, Virgin Islands, Jamaica, Cuba, Hispaniola (Dominican Republic and Haiti), Puerto Rico (Caja de Muertos, Culebra, Desecheo, Magueyes, Mona), and St. John's in the Virgin Islands. Its flowers are pollinated by bats such as Brachyphylla nana , Monophyllus redmani , and Phyllonycteris poeyi . Plants are found growing along with Bonellia stenophylla , Bourreria succulenta , Guaiacum officinale , and Maytenus loeseneri . [4]

Taxonomy

The species was first described as Cactus fimbriatus by Jean-Baptiste de Lamarck in 1785 and reclassified into the genus Stenocereus by Alicia Lourteig in 1991. [5]
