OROBANCHACEiE. 107 



generally tinged with brownish-purple, with the corolla narrower 

 and more curved than in any of the preceding species ; the lobes 

 of the upper lip connivent, making tlie upper lip keeled above so 

 as to form two, sides of a triangular prism. The stamens and style 

 nearly glabrous towards the apex, are siiflicicnt to distinguish it 

 from the preceding. 



I have been favoured with fresh specimens by Mr. G. S. Gibson, 

 of Saffron Walden. 



A plant which has been referred by some to this species, and by 

 others to O. lucorum (Koch), has been found near Epsom, Surrey. 

 Mr. Williamson, of the Royal Gardens, Kew, according to the 

 " Cybele Britannica," gives the following directions for finding the 

 plant : — " Erom the back of the grand-stand on Epsom race-course, 

 proceed through the fields to the town of Epsom, and the plant 

 will be found amongst clover, rarely among wheat, on the right- 

 hand side on the back of the hill. July, 184G."— (Cyb. Brit. Vol'. II. 

 p. 226.) I am unacquainted with O. lucorum (Koch), and do not 

 venture to pass an opinion upon the dried specimens of the Epsom 

 plant. The upper segment of the sepals is much broader and more 

 acuminated than in 0. elatior, with which it agrees in the stamens 

 being inserted a little way above the base, and by their upper por- 

 tion and the style being sub-glabrous. It is mucli to be desired that 

 some botanist would examine recent specimens of this plant, if it is 

 still to be found near Epsom. 



Tall Broom-rape.

This species has hitherto only been noticed on the roots of Centaurea scabiosa, and 

 is very rare.

Elowers spreading. Bracts shorter than the flowers, or only 

 slightly exceeding them. Sepals longer than the corolla-tube, 

 entire or (more rarely) 2-cleft ; the upper segment with 1 con- 

 spicuous nerve, sometimes with an indistinct one on each side. 

 Corolla sparingly pubescent with gland-tipped hairs ; tube rather 

 narrowly cylindrical, slightly curved, with the curvature greatest 

 towards the base ; upper lip scarcely notched, with the margins 

 erect ; lower lip 3-lobed, with the lobes nearly equal ; all crimped 

 and sharply denticulate. Stamens inserted a little below the 

 middle of the corolla-tube ; filaments hairy on the inner side
