原生地・分布（英語）:

説明（英語）: Genus of 17 species of deciduous shrubs occurring in hillside scrub in temperate South America. The modified branches form succulent, cylindrical or flat, triangular, mid- to blue-green or grey-green spines, which point outwards from the shoots, with one terminal spine to each branch. The opposite leaves are sparse or wholly absent, particularly on mature plants; both the stems and leaves photosynthesize. Small, tubular or bell-shaped flowers, with tiny petals and conspicuous calyces, are produced singly or in many-flowered clusters, either on or below the spines. Grow in a sheltered shrub border or against a warm, sunny wall. In areas prone to severe frosts, grow in a cool greenhouse.

耐寒性（英語）: Frost hardy.
