Baculellum articulatum, formerly known as Curio articulatus or Senecio articulatus, is an intriguing succulent with segmented, sausage-shaped stems. It can reach a height of 2 feet (60 cm) and spread slowly by underground stems. The stem segments are thick and fleshy and can grow up to 4 inches (10 cm) long and 0.8 inches (2 cm) in diameter. They are grey-green with darker green or purple markings just below the petioles. The leaves are green, flushed purple when exposed to intense light, usually divided into leaflets, and can measure up to 3.2 inches (8 cm) long. The plant loses its leaves and goes dormant in summer.

The white flowers usually appear in winter in small corymbs that can reach a diameter of about 0.5 inches (1.3 cm).
