Discussion

Zigadenus elegans has been treated previously as comprising two varieties, or two subspecies (W. B. Zomlefer 1997b). The western var. or subsp. elegans tends to be a smaller plant with a raceme or a 1–2-branched panicle and glabrous, sometimes glaucous leaves and stems; while the eastern var. or subsp. glaucus tends to be a larger plant with a paniculate inflorescence and glaucous leaves and stems. Because there is considerable evidence of intergradation between the two entities toward the middle of the range, including overlapping flowering times, they have not been formally distinguished here.
