Comments
An
extremely interesting population of A. retusus growing in
Tamaulipas, The majority of the plants are of distinctive appearance with
a raised rounded edge to the tubercle and lacking an apical areole, other
specimens have a more A. trigonus like appearance, typical A.
retusus types are also present. These plants may represent what Josef
Halda has described as A. retusus subsp. panarottoi, whilst
an interesting variant, the plants appear to fall within the range of
A. retusus subsp. retusus
