  INTRODUCTION
  Ortegocactus macdougallii is a highly appreciated 
  ornamental cactus, endemic to Mexico, and distributed 
  in a small area located in the municipality of San José 
  Lachiguiri in the State of Oaxaca (Alexander 1961, 
  Weightman 2004). It is the only species of the monotyp-
  ic genus Ortegocactus (Pilbeam and Weightman 2006, 
  Weightman 2004). Unfortunately, native populations 
  are threatened by extinction as a result of soil degra-
  dation and human over-collection of adult plants, their 
  fruits, seeds, and seedlings (Pilbeam and Weightman 
  2006). In addition to this, Ortegocactus macdougallii 
  has very slow growth rates, reduced sprout production, 
  low germination and self-incompatibility that results in 
  poor fruit and seed set, and low survival of seedlings 
  growing in natural habitats, which makes the future 
  of this plant species a critical issue. Therefore
