Flowers numerous, drooping, arranged in 2 rows in a secund 
spikelike raceme. Seeds rather numerous, affixed to 4 broad pla- 
centai approximating in pairs. 
Parasitical on the roots of trees, especially hazel, in damp 
shady places. Rather rare. Besides the hazel, it grows on the oak, 
beech, ash, elm, walnut, ivy, vine, and laurel. 
England, Scotland, Ireland. Perennial. Spring and 
early Summer. 
Rootstock branched, giving off slender fibres which attach them- 
selves by minute tubercles to the roots of the plant on which it is 
parasitic. Whole plant white, with a somewhat translucent appear- 
ance, frequently tinged with purple, clothed below with thick fleshy 
brittle scales. Branches short, thick, cylindrical, conical at the apex, 
with scales like the rootstock. Flowering-stem erect, fleshy, 3 inches 
to 1 foot high, white and glabrous at the base, tinged with purple or 
rose, and slightly pubescent towards the top, with a few scales in 
the lower part, terminated by a dense unilateral raceme, at first bent 
over like that of Monotropa, but straightening as the flowers expand. 
Flowers white, more or less tinged with purplish-pink, drooping or 
horizontal, each with a broadly ovate bract set obliquely on the stem 
at the base of the pedicel. Pedicels shorter than the calyx, clothed 
with jointed hairs. Calyx bilabiate, somewhat inflated, each lip 
cleft into 2 deltoid connivent segments, clothed with a few hairs. 
Corolla longer than the calyx ; upper lip entire or slightly notched, 
concave ; lower lip 3-lobed, with the lobes crimped at the margins; 
filaments hairy. Anthers cohering, fringed with woolly hairs. Style
