Mammillaria pennispinosa

  • First description by Krainz, Sukkulentenk. 2: 20 (1948)

  • Body: Plants solitary, eventually forming clusters. Stems globose, 3 – 4 cm (1.2 – 1.6 in) high and in diameter.
  • Roots: Tick taproots.
  • Sap: Without latex.
  • Tubercule arrangement:
  • Tubercule: Flabby, cylindrical.
  • Axil: Woolly at first, later naked.
  • Radial spine: 16 – 20, slender, straight, plumose, grayish white to yellow to orange to reddish, 5 – 8 mm (0.2 – 0.3 in) long.
  • Central spine: 1 – 3, pubescent, brownish red with yellow bases, 10 – 12 mm (0.4 – 0.5 in) long, one hooked.
  • Flower: White with pink midveins, to 15 mm (0.6 in) long and in diameter.
  • Fruit: Red, 15 – 20 mm (0.6 – 0.8 in) long.
  • Seed: Black.
  • Flowering period in Cultivation (Europe):
  • Minimum temperature: -6? C.
  • Habitat Substrate:
  • Geographic Distribution: Coahuila and Durango, Mexico. Altitude 1.200 – 1.350 m.
  • Comments: One of the hooked spined miniature, this species is difficult to keep growing in cultivation. Very prone to root rot, it needs a very open potting soil and a very careful application of water. Additionally, water should not be applied overhead, as the feathery spines will retain water and add to rotting problems. Full light short of the direct sun and high temperatures are helpful, and needed to encourage flowering.
