It is a squat solitary plant that often in culture produces offsets.

White, scented, slender, funnel-shaped , 2 to 9 cm long that open at night. The position of the stigma is at the top of the stamens. Each flowering lasts only one night, but that night it produces many flowers.

Stem
Green to pale green, approx 12 cm in diameter and 7-8 cm tall.
Radial Spines
9 to 11 interlacing, densely covering the plant, to 3 to 5 cm cm long, slightly recurved backwards and sitting on the plant like spiders.
Fruits
Club-shaped red 2,5 cm long. The plant produces seed-pods twice a year, when it flowers.
Areoles
Oval, sunken. Number of areoles per rib is 5 to 6 on plants with cephalium.
