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 

 Leguminiferae. Rather rare, but generally distributed over England. 

 In Scotland known only to occur in Dumfriesshire. In Ireland it 

 appears to be confined to the South-east of the island. 



England, Scotland, Ireland. Perennial. Summer. 



Stem very stout, 1 to 2 feet high, enlarged below the ground, 

 clothed with curved glandular hairs. Elowers about 1 inch long, 

 pale-yellow tinged with purple. Bracts variable in length, some- 

 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. 



Greater Broom-rape. 



French, Orobanche du Spartum. German, Biibenslengelige Sommerumrz. 



This species infests the rape or turnip plants, and has its peculiar characteristics ; 

 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.

Flowers ascending. Bracts shorter than the flowers. Sepals 

 entire, as long as the tube of the corolla or a little longer, with a 

 strong mid-vein, and usually inconspicuous ones on each side of it. 

 Corolla sparingly pubescent with gland-tipped hairs ; tube widely 

 cylindrical, regularly curved ; the upper lip notched, with the 

 margins slightly spreading ; lower lip 3-lobed, with the lobes 

 nearly equal; all crimped, distinctly denticulate. Stamens inserted 

 near the base of the corolla ; filaments hairy on the inner side 

 towards the base, their apex and upper part of the style sparingly 

 clothed with gland-tipped hairs ; stigma of 2 contiguous lobes, 

 pale-pink. 



Parasitical upon wild thyme on trap rocks. Rare. It occurs
