Genus of cacti From Wikipedia, the free encyclopedia
Acanthocereus is a genus of cacti. Its species take the form of shrubs with arching or climbing stems up to several meters in height. The generic name is derived from the Greek word άκανθα (acantha), meaning spine,[3] and the Latin word cereus, meaning candle.[4] The genus is native to the mostly tropical Americas from Texas and the southern tip of Florida to the northern part of South America (Colombia and Venezuela), including islands of the Caribbean.[5]

The plants form bushes which later usually overhanging or spreading and are rarely tree-shaped. Stems have 3 to 5 ribs, typically thin, with stout spines. The large, white, funnel-shaped flowers are night-opening, 12–25 cm (4.7–9.8 in) long and 6–12 cm (2.4–4.7 in) in diameter and open at night. The little scaly pericarpel and the long, stiff, upright flower tube are covered with a few thorns that soon decay and little wool. The fruits are spherical to ovoid or pear-shaped red or green, bare or thorny, tear-open or non-tear-open and contain broadly oval, shiny black seeds of up to 4.8 millimeter.[citation needed]
The name was first used by George Engelmann in 1863, although he did not describe its characters, leaving it to Alwin Berger in 1905 to define it as a subsection of Cereus. In 1909, Nathaniel Britton and Joseph Nelson Rose elevated Acanthocereus to a genus.[6]
