I think that this is a form of carnea, with the documented 4 central spines, upper and lowest the longest, and pink flowers. I can see no radial spines on this plant.
Meseta (or possible Mesita) means a small high plateau from the Spanish for table, and many flat topped hills and mountains in Spain and Mexico are called Mesa.Perhaps the best known Mesa de San Lorenzo is just north west of Tehuacan. The Mamms that grow there are M. haageana (sensu lato), M. mystax and M. carnea, together with some rarer species reported such as napina and pectinifera.
