Taxonomy

edit

First described as Echinocactus alamosanus in 1913 by Nathaniel Lord Britton and Joseph Nelson Rose. The specific epithet, alamosanus, refers to the plant's occurrence at Álamos in the Mexican state of Sonora, in northwestern Mexico.[5] Ferocactus alamosanus was later placed in the newly created genus Ferocactus by the same authors in 1922.[6]
