General: Fleshy root parasites, the stems short, 1-5 cm. long, much shorter than the 1-3 pedicles, which are 3-10 cm. long; plants strongly glandular-villous. Leaves: Leaves none; flowers without bractlets. Flowers: Flowers 1-3 on elongate pedicles; calyx 4-12 mm. long, the 5 narrow, sub-equal lobes longer than the tube; corolla brownish-yellow to violet, 2-lipped, 15-35 mm. long, the 5 lobes finely fringed; anthers glabrous or hairy. Fruit: Capsule 2-celled

Seed sample from 2011
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
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.
