🌵 Type | Echinocactus spiniflorus |
Greek akantha ‘spine’ + Greek kalyx ‘calyx’. For the sharp-tipped scales on the floral tubes. Compare the name of the type species, Echinocactus spiniflorus (= Acanthocalycium spiniflorum). Perhaps inspired by Spinicalycium, an earlier but invalid name for the same genus.
