Spotted Coralroot
Corallorhiza maculata
Orchid family (Orchidaceae)

Spotted Coralroot often grows in dense colonies. In the early spring look for clumps of dark red stalks of last year's plant, soon to be replaced by yellow-red stalks and new blossoms. These stalks can be confused with those of Pterospora andromedea (Woodland Pinedrops) but the latter are usually much stouter. The plant does not photosynthesize, but instead lives off fungi. Corallorhiza means "coralroot" in reference to a hard mass of that associate with fungi in the soil to absorb nutrients. "Maculata" is Latin for "spotted."

A herb is a plant whose stems die back to the ground in the winter.

A parasitic plant derives some or all of its nutritional requirements from another living plant.

Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom.

basal -- at the base, situated or attached at the base.

sheath -- a tubular or rolled part of an organ, e.g. the lower part of the leaf in most grasses.

A raceme is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along its axis.

rhizome -- root-like stems that may either grow horizontally at the soil surface or in other orientations underground.
