PHENOLOGY: Jul-Aug; Sep-Oct.
HABITAT: Limestone and dolostone woodlands, glades, cliffs, and outcrops.
COMMENTS: A. glauca is the more eastern component of a complex variously treated as two species or a single variable species, with or without recognized varieties or subspecies. A. elegans (in the broadest sense) ranges from QC and NY west to AK, south to n. OH, n. IN, n. IL, MO, IA, NM, AZ, and n. Mexico; disjunct in the mountains of w. VA, e. WV, and w. NC. Two taxa have often been recognized, at the specific, subspecific, or varietal level. The more eastern taxon (epithet glauca – see synonymy below) ranges from NB west to ND, south to w. NC, TN, and MO, and is distinguished by glaucous foliage, paniculate inflorescence, and tepals often purplish or brownish basally. The more western taxon (epithet elegans), occurring east to the MN and MO, has the foliage greener, the inflorescence often only racemose, and the tepals yellow.

ABOUT FAMILY (Weakley Flora)
Melanthiaceae Batsch 1802 (Bunchflower Family)
SUMMARY: A family of about 8 genera and 80 species, mostly temperate and northern hemisphere, but extending into South America (Peru).
REFERENCE: Dahlgren, Clifford, & Yeo (1985); Zomlefer (1997a)=Z; Zomlefer (1996, 2003); Tamura in Kubitzki (1998a); Tamura et al. (2004); Zomlefer et al. (2001).
ABOUT GENUS (Weakley Flora)
Zigadenus Michaux 1803 (Death-camas)
SUMMARY: As redefined, a monotypic genus of se. North America. A molecular systematics study by Zomlefer et al. (2001) gives strong support to a treatment recognizing Zigadenus as monotypic (Zigadenus glaberrimus), Anticlea (including for our area the former Zigadenus elegans ssp. glaucus), Stenanthium (including for our area Stenanthium spp. and the former Zigadenus densus and Z. leimanthoides). Zigadenus (as redefined) has a chromosome number of 2n=54 (Zomlefer, McKain, & Rentsch 2014), unique in the family.
