Lophocereus schottii, the senita cactus,[3] is a species of cactus from southern Arizona and north-western Mexico, particularly Baja California and Sonora. Ultramafic soils facilitate the endemism of plant species and are often associated with their distribution.[4]
Description
[edit]Lophocereus schottii grows tree-shaped to shrub-like with yellow-green, more or less upright shoots, which often develop into thickets with more than 100 shoots. It reaches heights of 1 to 3 meters and shoot diameters of 5 to 10 cm (2.0 to 3.9 in). A tribe is rarely formed. There are 4 to 13 clearly defined ribs. The 1 to 3 strong, gray central spines are 1 to 3 cm (0.39 to 1.18 in) long. The 3 to 5 marginal spines are gray and 0.5 to 1.5 cm (0.20 to 0.59 in) long. The terminal pseudocephalium consists of bristly, flexible, gray spines. It occasionally grows to be more than 100 cm (39 in) long.
The funnel-shaped flowers appear laterally from the pseudocephalium and open at night. They are white to deep pink, up to 5 cm (2.0 in) long and reach a diameter of 3 cm (1.2 in). Its pericarpel and flower tube are covered with scales and hairs. The spherical, red fruits contain red pulp and reach a diameter of 1 to 3 cm (0.39 to 1.18 in). They are edible, but are rarely used as food.[5]

Ecology
[edit]The senita cactus exhibits mutualism with the senita moth. The senita moth is the only nocturnal pollinator of the cactus, and the moth relies on the cactus as a host for reproduction.[6]
Taxonomy
[edit]The first description as Cereus schottii was made in 1856 by George Engelmann.[7] The specific epithet schottii honors the German naturalist and plant collector Arthur Schott, who was involved in surveying the border between the United States and Mexico. Nathaniel Lord Britton and Joseph Nelson Rose placed the species in the genus Lemaireocereus in 1909. Further nomenclature synonyms are Pilocereus schottii (Engelm.) Lem. (1862) and Pachycereus schottii (Engelm.) D.R.Hunt (1987).[7]
