Etymology

Latin ĕchīnus ‘sea-urchin, hedgehog’ + Latin –ŏīdĕus ‘-like’. For the similarity to Mammillaria echinus (= Coryphantha echinus). Quehl: “The species is superficially very similar to Mam[millaria] echinus and has therefore been named Mam[millaria] echinoidea.” Compare Coryphantha pseudechinus.
