USDA Native Status: L48 (N), CAN (N)

A monotypic genus, Pterospora is achlorophyllous and mycoheterotrophic; that is, it utilizes ectomycorrhizal fungi of the genus, Rhizopogon to obtain carbon from the roots of coniferous trees.

The stiffly erect, leafless stems of this reddish-brown plant often grow in clusters, and are covered with glandular hairs. Pale yellowish-brown egg-shaped flowers hang in a long raceme.

Stems grow for only one year, but remain as dried stalks for several years. The genus name, from Greek words for "winged seeds," refers to the net-like wing at one end of each minute seed that carries it to a new site as it is sprinkled from the capsule.
