The roughly eight to 12 (-17) low, straight down ribs are rounded and humped. The one to three white or brownish central spines , which can occasionally be missing, are protruding. The twelve to 14 (up to 26) (rarely from seven) thin, bristle-like, glassy white radial spines are bent back and 2 to 6 millimeters long.

The delicate purple-pink to white often unisexual flowers are usually 3.5 to 5 centimeters long and have the same diameter. The pericarpel is short, dark brown-green and shows some light-edged scales. Stamens , styles and stigmas are white, the pollen is yellowish. The blue-green to whitish green fruits are spherical, pear-shaped or spindle-shaped. They are up to 1.5 centimeters long and 1.2 centimeters in diameter. The seeds are 1.2 to 1.4 mm long and more or less spherical.
