|discussion=<p>D. Isely (1998) suggested that large-flowered individuals within the range of var. micranthiformis are intermediates with var. austrinus. Ranges of these varieties are discrete, however, and larger-flowered plants may be part of normal variation. Variety micranthiformis occurs in approximately one-fourth of each state around the Four Corners area.</p>
