|discussion=<p><i>Sclerocactus parviflorus</i> has an extensive range and great morphologic variation. Many named segregates have been proposed (L. D. Benson 1982; K. D. Heil and J. M. Porter 1994; F. Hochstätter 1995b) and some of these clearly merit recognition at the subspecific or varietal level. However, we are not attempting to subdivide this very complex group. Considerable work remains in understanding morphologic diversification within this species.</p>
