Mammillaria luethyi

  • First description by George S. Hinton, Phytologia (1996)

  • Body: stems single or branched with up to 7 heads, apex rounded to flattened. 1.5 to 2 cm diameter.
  • Roots: taproot
  • Sap: aqueous.
  • Tubercule arrangement:
  • Tubercule: slender cylindric, 5.5mm long for 1.3mm large.
  • Axil: naked.
  • Radial spine: more than 80, 0.4 to 0.6 mm long, forming a dense cluster of 1.3 to 1.8mm.
  • Central spine: none.
  • Flower: Up to 3cm long and wide, light magenta coloured at the top and white at the base
  • Fruit: globular, 4.5mm in diameter, nearly completely sunken in the stem, yellowish green to reddish green.
  • Seed: globular, 1 mm x 1 mm, testa black and finely pitted
  • Flowering period in Cultivation (Europe): April
  • Minimum temperature:
  • Habitat Substrate: limestone slabs.
  • Geographic Distribution: MEXICO in the state of COAHUILA in the Sierra Paila.
  • Comments: In culture, mineral substrate. Normally found as a grafted plant, but growers are reporting that it is easily grown on its own roots. Grafted plants are prone to more rapid growth, and therefore are sometimes not as tightly spined as they should be. Bright light will encourage the very dark green color that is possible with this plant, while dimmer light will produce plants of a much lighter green.
