Anticlea glauca Kunth. Phen: Jul-Aug; Sep-Oct. Hab: Limestone and dolostone woodlands, glades, cliffs, and outcrops. Dist: NB west to ND, south to w. NC, TN, and MO.
Origin/Endemic status: Native
Taxonomy 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 inflorescences, 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.
