Of this relationship are flowers collected by A. 
Dominguez from the Cerro de Macha, Cordoba, Argentina; in these specimens the scales 
are long, linear, chartaceous, and erect; the flowers are 5 to 6 cm. long; the outer perianth- 
segments and often the inner have acuminate or mucronate chartaceous tips. (For 
further discussion see Echinocactus spiniflorus, page 178.)
