Mammillaria parkinsonii

  • First description by Ehrenberg, linnaea 14: 375 (1840)

  • Body: Plants solitary at first, later branching dichotomously. Stems depressed globose to cylindrical, blue-green, to 15 cm (5.9 in) high, 10 – 15 cm (3.9 – 5.9 in) in diameter.
  • Roots:
  • Sap: With latex.
  • Tubercule arrangement:
  • Tubercule: Pyramidal.
  • Axil: With wool and bristles.
  • Radial spine: 30 or more, fine, white, slightly curved, 4 – 6 mm (0.2 in) long.
  • Central spine: 2 – 5, usually curved slightly downwards, stiff, whitish with dark tips, upper ones 6 – 8 mm (0.2 – 0.3 in) long, lower ones to 38 mm (1.5 in) long.
  • Flower: Pale yellow with red midveins, 12 – 15 mm (0.5 – 0.6 in) long and in diameter.
  • Fruit: Club shaped, reddish orange, to 10 mm (0.4 in) long.
  • Seed: Brown.
  • Flowering period in Cultivation (Europe):
  • Minimum temperature: -4? C.
  • Habitat Substrate:
  • Geographic Distribution: Queretaro, Mexico. Altitude 1.200 – 2.400 m.
  • Comments: One of the species with the capability of forming very large clumps. In order to keep the clumps tightly formed, high light levels and steady growth are needed; otherwise there is the danger of having a number of elongated heads that are somewhat separated from one another. This species is especially variable in spine length. Grows by dichotomous division.
