Description
Fleshy root parasites, 1-5 cm. stems, which are much shorter than pedicels, which are 3-10 cm. long. Plants glandular-hairy above.
Leaves lacking, flowers without bractlets.
Corolla pale to deep purple, occasionally ochroleucous or yellow, pedicels yellowish to dull reddish. Corolla lobes about 2 times as long as corolla tube.
Fruit is a 2-celled capsules.[2][3]
Bloom Period
April to August[4]
Distribution
Southern BC and southern Alaska south, on both sides of Cascades, to California, East to Alberta and Rocky Mountain States.[2]
Habitat
Moist to dry meadows and forest openings in the lowland, steppe and montane zones.[3]
Mostly parasitic on the roots of herbaceous Asteraceae, Saxifragaceae and Sedum.[2]
Uses
The whole plant is edible raw or cooked. Medicinally, A. purpureum is laxative and sedative.[5]
Seed
Aphyllon purpureum
Seed sample from 2011
Features
Average Measurement: 0.2 x 0.1 x 0.1
Measurement Range: L: 0.1 – 0.3, W: 0.1 – 0.2, D: 0.1 – 0.2
Latitudinal Cross Section: elliptical 
Longitudinal Cross Section: elliptical 
Shape: Seed very small, slightly narrower at hilum and opposite apex. Seed generally egg shaped, some specimens more slender than others.
Color: Most seeds brown, some tan.
Surface: Seed coat deeply honeycombed, and somewhat iridescent.
Basic Explanations and Assumptions:
The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.
Measurements included are the mean average for each measurement of ten separate seeds.
All measurements in millimeters unless otherwise noted.
