Hedgehog cactus has eight to twelve spines per areole, with central spines being difficult to distinguish from radial spines. Plants may vary from densely spiny to no spines at all.
The several varieties are so different looking that the only uniting factor is the bright red bloom and rounded petals. Some authorities recognize the following varieties:
E. triglochidiatus var. triglochidiatus
E. t. var. arizonicus (Rose) L. Benson Arizona hedgehog cactus (endangered): oak woodland
E. t. var. gurneyi L. Benson : Chihuahuan desert, desert grassland
E. t. var. inermis Rowley spineless hedgehog cactus
E. t. var. melanacanthus (Engelm.) L. Benson :Rocky Mountain montane forest, pinyon-juniper woodland
E. t. var. mojavensis (Engelm. & Bigel.) L. Benson : Mojave desert, chaparral
E. t. var. neomexicanus (Standl.) Standl. ex W. T. Marshall : oak, pinyon-juniper woodland
E. t. var. paucispinus (Engelm.) Engelm. ex W. T. Marshall
The variety E. t. variety toroweapensis Fischer has been proposed.
A spineless form of E. t. var. mojavensis occurs in the mountains and mesas of western Colorado and eastern Utah.
Echinocereus coccineus is now considered a distinct species.
