Plants unbranched (very rarely branched), appearing pure white or slightly yellowish, smooth, and shiny in general aspect. Stems flat-topped, disk-shaped, short cylindric, or cylindric, 2–5 cm diam. Spines (40–)50–90 per areole, in more than 3 superimposed series; mature lateral spine clusters uniformly white to creamy yellow, 2–2.5(–4) mm diam.; longest intact spines 4.5–7 mm; worn spines 0.1–2 mm. Flowers conspicuously exserted beyond longer spines at stem apex, 1–1.7 × 1–1.7 cm; inner tepals 13–21 per flower, 5–6(–9) × 1.5–2.3(–3) mm; stamens 20–40. 2n = 22.
Phenology: Flowering spring–early summer (May–Jun); fruiting summer–fall.
Habitat: Chihuahuan Desert on rocky, barren hills of sedimentary substrates
Elevation: 700[-1400] m
Distribution
Tex., Mexico (Coahuila).
