Mammillaria erythra

Mammillaria erythra
Reported from Veracruz, on the border with Puebla, at Puerto del Aire, 1850m altitude on limestone conglomerate, this species seems to be merely a short spined form of the variably spined M.mystax from this general area.
Hunt has recently maintained it as provisionally accepted, althought previously he was more positive in his  ascertion that it "is simply a distinctive form with reduced spination".
I favour his earlier opinion
