In clover fields, thickets, and bushy hilly places, on a gravelly soil, 

 not uncommon ; but never on the roots of Broom or Furze. 

 Rev. Dr. Sutton. 



Perennial. July, August. 



Taller, and of a more yellowish hue than the former, with flowers 

 of a lighter purple, more wavy in their margins ; their upper lip 

 lobed. They are commonly three times more numerous in the 

 spike than in that species, and of a smaller size. But their clear- 

 est and most essential difference, first remarked by Dr. Sutton, 

 consists in the stamens being downy in their lower half, within - 

 side, and smooth at the top ; while the germen and style are all 

 over perfectly smooth. The stamens proceed from a higher part 

 of the tube than in O. major. 



3. O. minor. Lesser Broom-rape. 



Stem simple. Corolla nearly cylindrical ; lower lip with 

 curled segments, the middle one largest and lobed. Sta- 

 mens fringed. Style smooth.

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 fewerflowers than O. major. The whole plant is ge- 

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

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

 the others, in decay. Stem often wavy. Calyx-leaves unequally 

 lobed, sometimes undivided. Cor. not at all tumid ; 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
