• DESCRIPTION
A monotypic genus of columnar plants branching from the base, with erect stems reaching 5 m high and 10 cm in diameter, with numerous ribs (up to 27) weakly tuberculate. Areoles very close, woolly, spines relatively short (ca. 2 – 3 cm). When stems are mature, they develop a longitudinal dense cephalium consisting of spines and red wool, becoming grey with age.
Flowers nocturnal remaining open in the morning, self-sterile, appearing near the apex, widely bell-shaped, white yellowish, pale to intense pink, with the floral tube covered with numerous bristles and with pinkish wool, pollinated by bats. Fruits scaly, deeply sunken in the cephalium. Seeds roughly egg-shaped, dark brown, shiny, slightly tuberculate and striate, dispersal myrmecophilous.
• HABITAT

• DISTRIBUTION
Bolivia (Chuquisaca, Cochabamba, Santa Cruz).
