Neoraimondia is a genus of plants from the cactus family(Cactaceae). The botanical name of the genus honors the Italian naturalist Antonio Raimondi (1826–1890). The addition "Neo" was necessary because the name Raimondia was already given to a genus of the Annonaceae .

description

The shrubby to tree-like, candelabra-like species of the genus Neoraimondia are branched and reach a height of up to 15 meters. The upright, usually gray-green shoots reach a diameter of up to 40 centimeters. Their 4 to 8  ribs are far apart. The large, round to elongated areoles are cone-like short shoots . They are tomentose brown, thorny and continue to grow over many years. The up to 12 (or more) thorns are flexible and up to 25 centimeters long.

The funnel-shaped flowers are pink or cream-colored, arise from elongated short shoots and open during the day. Your flower cup and the flower tube have scales, felty areoles and sometimes bristles.

The spherical fruits have brown felted areoles with short thorns. The black seeds are finely dotted and surrounded by a slimy shell.

Systematics and distribution

The genus Neoraimondia is common in the arid regions along the Peruvian coast and in the Andes of Peru and Bolivia . The genus was first described in 1920 by Nathaniel Lord Britton and Joseph Nelson Rose . They assigned her as the only species the species Pilocereus macrostibas described by Karl Moritz Schumann in 1903 . Curt Backeberg was able to show that the plant was described as Cereus arequipensis by Franz Julius Ferdinand Meyen as early as 1834 . Its correct name is therefore Neoraimondia arequipensis .

The genus includes the two species:

• Neoraimondia arequipensis (Meyen) Backeb.
  • Neoraimondia arequipensis subsp. arequipensis
  • Neoraimondia arequipensis subsp. roseiflora
• Neoraimondia herzogiana (Backeb.) Buxb.

A synonym of the genus is Neocardenasia Backeb.
