Characteristics:
Spotted coral root is a small flowered orchid which grows to
20-50 cm tall. The stems have 2-4 sheathing scales. The plant is purplish to
reddish in color, although it may be a somewhat yellow-tannish color as an albino
form.
The flowers number up to 30, and may be well spaced to crowded
on the upper stem. The sepals are from 8 to 10 mm long and narrowly oblong to
narrowly oblanceolate in shape. The spur found on Corallorhiza mertensiana
is absent or greatly reduced on this species. If present, the spur is yellowish
in color. The petals are slightly shorter than the sepals.
The lower petal lip is white, with red spots covering it. Corallorhiza
maculata may be identified from Corallorhiza mertensiana by its generally
lighter red coloration, white lower lip with red spots, and greatly reduced
or absent spur.
Habitat:
Spotted coral root is found in moist, coniferous to deciduous
forests.
Range:
Spotted coral root is found from British Columbia east to Quebec,
and south through Michigan through the western United States to Utah, New Mexico,
and northern Mexico.
