Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Parasitic, herb which is symbiotic with fungus, having a simple stalk, reddish-brown in color, whole plant densely glandular-hairy, can produce several stems from a ball-like root mass, up to 1 m tall. Leaves: This plant lacks chlorophyll and has no true leaves, however, sometimes scales growing on the stalk can protrude outward and have the appearance of leaves. Flowers: Small, bell-shaped, white, cream, or pink flowers, nodding, the inflorescence forming a dense, overlapping cluster at the terminal portion of the stalk. Each flower is supported on a slender pedicel, with 5 triangular sepals, also reddish. The flowers have 5 reflexed lobes at the tips, forming a narrow opening. Stamens 10, anthers having 2 recurved awns the length of the sacs. Fruits: Small, rounded capsules, nodding, 5 locular, seeds are small, round, and red when young, having a translucent, rounded wing protruding from one side. Ecology: Found on calcareous substrates in mixed deciduous and coniferous (pine) forests, from 6,000-9,500 ft (1829-2896 m); flowers June-August. Notes: This interesting, parasitic plant enjoys the cooler temps found in coniferous forests, especially pine forests. Look for its red stalks sprouting in unlikely places, especially in damp areas or areas with well-composted duff. The tiny seeds are especially cool with their transparent wings, reminiscent of fly wings. The stalks can sometimes be sticky to the touch. Ethnobotany: An infusion of the plant was taken to treat lung hemorrhages, and used as an emetic, externally, an infusion was used as an astringent, and snorted to treat nosebleeds, an infusion of the roots were taken to treat gonorrhea. The plant was was roasted and eaten, and the leaves were smoked in the kiva. Etymology: Pterospora is from the Greek pteron for wing and sporos for seed, while andromedea means resembling Andromeda (the genus of bog-rosemary). Synonyms: None Editor: LCrumbacher, 2011
