  • Seed: Black, 0,8 – 0,9 mm long and 0,6 mm wide
  • Flowering period in Cultivation (Europe): Mai – june.

  • Habitat Substrate: In humus soil on granitic rocks and in brushwood in open plains.
  • Geographic Distribution: Mexico, Baja California, Sierra de la Laguna , east of Todos Santos. Altitude to 450 m.
  • Comments: In spite of the very little diffrences ( in spination), Hunt refuses to accept this M. verhaertiana, because B?deker has not properly typified the distribution area. In fact, B?dekers description was the first (1912) and the description of phitauiana came much later (1931) and was a redescription of verhaertiana. Phitauiana is accepted as name in English speaking countries, but rejected by some Europeans, who prefer verhaertiana.
