The genus is represented by plants with cylindrical, often solitary or branching stems covered with areoles bearing spines. Leaves are reduced to small tubercles. Stems can reach various sizes depending on the species.
Flowering occurs in spring and summer. Flowers are funnel-shaped, symmetrical, up to 7 cm (2.8 in) long and up to 3 cm (1.2 in) in diameter, located at the top of the stem. Flower coloration varies from bright pink to red. After flowering, berry-like fruits containing small black seeds are formed.

The coloration of the stem is green or grayish-green.
