*According to Kimnach(2005) and Pilbeam(2008), this clone was reputedely collected ca. 15km of Ciudad Victoria, near Reja, Cerro de la Reforma, 2000m, on granite rocks, Tamaulipas state of Mexico, August 1971, by Alfred Bernhard Lau 036.
As far as I studied there has been no record of this species in Tamaulipas state… rather in Coahuila and Nuevo León. Maybe the locality data has erroneously been suggested? 🤔
