Characteristics:

The striped coral root is a striking and attractive perennial wildflower when seen in nature. The stout flower scapes are flesh colored to red-purple tinged and from 15-40 cm high. Three to four lighter colored sheathing scales are found on the scape (See photo at right.).

From 7-30 flowers are found in a spike up to 20 cm long atop the scape. Individual flowers are flesh-colored or light pink with 3-4 narrow, longitudinal, reddish-brown or purple stripes. The oblong-lanceolate sepals range from 10-17 mm long and from 2-4 mm wide. The lateral pair of sepals are not joined and thus a spur is lacking. The petals are shorter but wider than the sepals, measuring up to 6-8 mm wide. The lip is broadly oblong-elliptic, measuring 8-15 mm long and 6-8 mm wide. Its margins are not lobed, but are upturned and thickened.

Habitat:

The striped coral root may be found in shady coniferous to deciduous forests.

Range:

The striped coral root may be found from British Columbia south to Sierran California and east to Quebec or as far east as Michigan. In the Rocky Mts it can be found south through Utah and New Mexico and into northern Mexico.

In the Columbia River Gorge, it may be found between the elevations of 100'-2500' from west of Eagle Creek eastward to the Columbia Hills, north of The Dalles, OR.
