[edit | edit source]It has a globular body about 4 inches (10 cm) high and up to 18 inches (46 cm) wide, with typically in maturity 13 to 21 vertical ridges or ribs, based on its adherence to the primary Fibonacci series. Areoles are 5 to 10 mm long with 1-4 central spines that are 3.5 cm long and 6-8 radial spines that are 2-3 cm long. Spines range from yellow to red, and curved. The plant blooms from early spring to summer. It is most noteworthy for its pink, approx. two inch (5 cm) wide flowers, which have approximately 200 tepals arranged in a continuous spiral series from perfect sepals on the outside gradually morphing into perfect petals near the center. Fruits are red and spherical 4 x 3 cm with 2 mm long dark brown seeds. [3]

Taxonomy
[edit | edit source]Carl Friedrich Philipp von Martius first described Echinocactus macrodiscus in 1832. The name "macrodiscus" comes from the Greek words "makros" meaning 'large' and "diskos" meaning 'disc,' referring to the species' large, flat, disc-shaped shoots. In 1922, Nathaniel Lord Britton and Joseph Nelson Rose classified it under the genus Ferocactus.
