1. According to E. Walther Echeveria runyonii has been found in a garden at Matamoras, Tamaulipas, Mexico, as a cultivated plant, and no habitat was known. The indication in IHSP of Nuevo León as distribution region is wrong.
As a footnote M. Kimnach adds that “it has recently been found wild in Nuevo León” – this is also not correct, it has recently been collected wild in Tamaulipas.
This means that most likely there is no E. runyonii in Nuevo León.
Also the former var. macabeana is only known from cultivation.
2. Several cultivars of this species has been named, e.g. ‘Texas Rose’, ‘Dr. Butterfield’, ‘Lucita’, ‘Tom Allen’ (Australia). These plants are not conspicuously different from E. runyonii and the names may well be just nursery names for plants either not recognized as the species or renamed for the sake of listing a new name in a catalogue. To our knowledge none of these cultivars has been described or defined, so it is not even clear whether the above mentioned names are applied properly. Moreover from leaf you can get any of those forms, even 2 leaf shapes growing off one leaf, and at any time they can turn into ‘Topsy Turvy’.
Therefore these names are not taken into account here.
