Ecuador – short-spined Trichocereus pachanoi

Image

  Three images shared by Michael Smith of  short-spined Trichocereus pachanoi growing in Ecuador.
  Spine length can be extremely variable so it surprisingly can often be a feature that does not help much with species assignment in this area. (Trichocereus peruvianus similarly expresses a range of spination from short to long.)
