In clover fields abundantly. 



Very frequent in Norfolk. Mr. Rayer observed it in Kent, and the 

 Bishop of Carlisle near Crickhowel, Brecknockshire. 



Annual ? July, August. 



Of much more humble growth than the last, and smaller in every 

 part, with fewer powers than O. major. The whole plant is ge- 

 nerally of a light, but dingy, purplish hue, though occasionally 

 of a uniform pale yellow j always turning brown and dry, like 

 the others, in decay. Sto?! often wavy. Ca/2/:c-Zeaj;es unequally 

 lobed, sometimes undivided. Cor. not at all tumid j upper lip 

 unequally notched, not cloven, except from age or accident. 

 Stam. thickly fringed in their lower part. Germ, and style 

 smooth. Stigm. purple. 



4. O. rubra. Red Fragrant Broom-rape. 



Stem simple. Corolla somewhat tumid ; upper lip cloven ; 

 lower in three nearly equal segments. Stamens fringed 

 at the base. Style partially hairy. Calyx-leaves lanceo- 

 late, undivided.

On basaltic rocks in Ireland and Scotland. 



Plentifully at Cave hill, near Belfast. Mr. Templeton. At StafFa, 

 and near Kirkakly ; also on the Giants' Causeway, where Mr. 

 Templeton had previously found it. Dr. Hooker. 



Perennial. July. 



Root of numerous rather woody fibres, creeping along the unequal 

 surface of the basaltic rocks, under a superincumbent soil of 

 about five inches of decayed rock and zeolite. Mr. Templeton 

 could never perceive the roots to be parasitical. Dr. Hooker 

 observes that this species is entirely confined to basaltic rocks, 

 covered with a very thin coat of earth. The whole plant is of a 

 rusty purplish red, the bracteas rather browner. Stem a foot 

 high, tumid and densely scaly at the base, clothed above with 

 glandular viscid hairs. Fl. about 20, not very densely spiked,
