  • Strombocactus disciformis (DC.) Britton & Rose: the stem is flattened or spherical, blue-green with greyish tinge 3 to 8 cm high and 3 to 9 cm across. It is composed of hard, spirally arranged rhomboid tubercles that are flattened and almost truncated above.
  • Strombocactus disciformis f. cristatus hort.: Crested form.
  • Strombocactus disciformis subs. esperanzae Glass & S.Arias: (= S. pulcherrimus) is very similar to S. disciformis the only noticeable difference is the colour of the flowers that are bright magenta.
  • Strombocactus disciformis subs. jarmilae (Halda) Halda: like S. disciformis but with a smaller body, small flowers, long thin spines and some other minor differences. Distribution: Northern Mexico (Querétaro and Nuevo León)
  • Strombocactus disciformis f. polytomicous hort.: Polytomy is a form of cristation, an apex divided in a lot of smaller apexes. It is very unusual to see such a Strombocactus.
  • Strombocactus disciformis cv. Cactus Art: odd monstrous plant forming crowded clumps or mounds, and most plants will crest readily. Areoles felt-like in relief 2-4 mm broad, greenish at the stems apex when young. Spines mumerous very short bristle-like.
  • Strombocactus disciformis cv. Cespitosa: This is a strange plant that forms lots of axillary shoots in a continuous series on almost each node starting from the base of the stem, while the typical Strombocactus disciformis is usually solitary.
