Plant Description: Spotted Coralroot is a  reddish brown, perennial saprophyte, but can also be yellowish brown.  The stem is 7 to 22 inches tall.  It has a few clasping, purplish bracts in place of leaves.  There are 10 to 30 flowers on the upper half of the stem.

Flower Description: The 5 upper tepals are very much alike, purplish and narrow and less than 1-inch long. They flare out and curve over the lower lip. The lower lip is white with distinctive magenta spots.  It is shorter and broader than the others, has two very short lobes and is roughly toothed at the tip. The two upper petals may also have spots. There may or may not be a very short spur. The stamen and style are united to form a column which curves out over the lip. All-white specimens also occur.

Ecology: Spotted Coralroot grows in dense forests at low to middle elevations.

Notes:

  • Spotted Coralroot is a saprophyte, feeding off decomposing forest litter and hence needs no chlorophyll or sunlight.  It is dependant on a complex group of fungi present in the soil.
  • It gets its name from the spreading, coral-like rhizomes.
