Mountain Deathcamas - Zigadenus elegans
MNPS Threat Rank
Stems 10–60 cm. Leaves glaucous, 8–30 cm × 2–10 mm. Inflorescence a raceme or branched panicle; flowers well-separated below; pedicels 5–40 mm long. Flowers: tepals 6–11 mm long, the inner longer with a claw 0.5–1 mm long; stamens as long as the tepals. Capsule 12–20 mm long (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX)
Gleason and Cronquist (1991) made the distinction between the subspecies as Z. elegans subspecies glaucus being the plant occurring in the eastern portion of North America grading into subspecies elegans, the mainly cordilleran and western subspecies.
Fernald (1950) separated the plants into two species, however, the descriptions given can be applied to the plants now considered subspecies of Zigadenus elegans.
Considered collectively, Zigadenus elegans is distributed across much of the United States and Canada, ranging from Eastern Quebec to New York, disjunct in the southern Appalachian region, west to Arizona and New Mexico, north to Alaska. When broken down according to Gleason and Cronquist (1991) and Kartesz (1994) the subspecies have the following distributions:
Zigadenus elegans ssp. elegans: Alaska south to Arizona and New Mexico, eastward to Manitoba, Minnesota, Iowa, and Missouri (Gleason and Cronquist 1991, Gleason and Cronquist 1963, Fernald 1935).
Zigadenus elegans subspecies glaucus: Eastern Quebec to New York, west across the northern U.S. and adjacent Canada, occasionally in southern Ohio and northern Illinois, to the cordilleran region (grading into Z. elegans subspecies elegans in Minnesota and Iowa); disjunct in the southern Appalachian region (Virginia to North Carolina) and in the Ozarks (Missouri and Arkansas) (Gleason and Cronquist 1991, Gleason and Cronquist 1963, Fernald 1935).
