Cactaceae

Description

Cereus hildmannianus is a species of cactus from southern South America. Its distribution is uncertain but probably includes Brazil, Paraguay, Uruguay and Argentina. Cereus hildmannianus has a tree-like growth habit with a distinct trunk after which it branches freely up to 10 m (33 ft) high. Its stems are up to 15 cm (6 in) across, have 4�6 ribs and are divided into segments. They are blue-green in colour when young, becoming duller green with age. Stems are usually spineless (except in subspecies uruguayensis). The white flowers are very large, up to 25�30 cm (10�12 in) long, and are followed by fruits which are red when ripe.
