Characteristics:
Meadow death camas is a beautiful but deadly lily. It consists
of a single stem arising to 50 cm from a ovoid bulb (2-3 cm long). The leaves
are basal, linear in shape with parallel venation, and may range in length from
10 to 40 cm long. The leaves are keeled, and may be somewhat V-shaped in cross-section,
especially near the base.
The inflorescence is a primarily a short raceme, rarely longer
than 15 to 20 cm. The pedicels are strongly ascending. The flowers consist of
six unequal tepals, all of which are separate. These are no longer than 5 mm
long.
To identify this plant from the similar Zigadenus
paniculatus, meadow death camas has the shorter inflorescence, and where
the inflorescence may be of similar length, meadow death camas has single flowers
arising from the stem (see photos), while panicled death camas has clusters
of flowers arising from the stem, especially in its lower inflorescence.
As mentioned above, this plant is deadly to ingest. It is sometimes
found interspersed with the edible camas, and native tribes often removed it
from the camas beds while both were in bloom, as the bulbs of both are similar.
Habitat:
A widespread species, meadow death camas may be found on coastal
"prairies" and on the grassy bluffs above the sea to the more arid prairie hillsides,
sagebrush slopes and into montane forest openings.
Range:
Meadow death camas is found from southern British Columbia to
Alberta and southwestern Saskatchewan in the north, south along both sides of
the Cascades to Baja California, and east to the Great Plains of North and South
Dakota, Nebraska, and Colorado.
In the Columbia River Gorge, it may be found between the elevations
of 100'-2500' from adjacent to Crown Point in the west to near Horsethief Butte
in the east.
