Plants recognized as var. scribneri are smaller but otherwise essentially similar to typical plants, except for a tendency to produce bluish rays. They occur mostly at higher elevations than more typical plants. P. Lesica (2005) maintained var. scribneri and mapped the two varietites as essentially congruent in geographic range.
