gland-tipped hairs ; tube wide, sub-campanulate, regularly curved ; 
the upper lip scarcely notched, with the margins spreading ; the 
lower 3-lobed, with the middle lobe twice as large as the others ; 
all the lobes waved, indistinctly denticulate. Stamens inserted at 
the base of the corolla ; filaments glabrous towards the base, their 
upper part and the style glandular-pubescent. Stigma of 2 diva- 
ricate lobes, pale-yellow. 
Parasitic on the roots of furze and broom and other shrubby

times considerably exceeding the flowers, at other times only slightly 
longer. Plant pubescent with gland-tipped hairs, yellowish, often 
tinged with purple, soon fading to purple.

but it is suggested by some writers as possible that the colour and configuration of 
the parasite are affected by the peculiar sap of the plant on which it feeds ; that the 
influence of this stolen nourishment is considerable, and that the number of species 
therefore appears very much larger than it really is.
