200 ENGLISH BOTANY. 



Corolla slightly curved throughout ; lower lip with the segments 

 nearly equal. 



Parasitical on clover and many other plants. Common, and 

 generally distributed in the South of England ; rare in the 

 North and AVest, where York and Ilereford are respectively its 

 boundaries. In Ireland only where introduced with clover-seed. 

 England, [Ireland]. Perennial. Summer and Autumn. 



Stem 4 to 20 inches high. Elowers f to J inch long, white or 

 yellowish, generally stained and striped with dull-purple. 



This is usually said to be an annual, but I have seen it come up 

 in successive years in a flowerpot on Pelargonium, although the 

 spike did not ripen seed.

Corolla bent into a quadrant in the lower third, the upper 

 two-thirds of the back nearly straight ; lower lip with the middle 

 segment conspicuously larger than the others. 



Parasitical on Daucus in Whitesand Bay, Cornwall ; near Ply- 

 mouth, Devon ; on the under-cliff, south-east of St. Margaret's Bay, 

 South Kent. On Eryngium maritimum, near Cobo, Guernsey ; and 

 St. Ouen's Bay, Jersey. 



England. Perennial. Summer. 



Stem 6 to 20 inches high. Elowers f inch long, usually more 

 purple than in O. minor, of which it is perhaps only a variety. 



There are several other forms of 0. minor which possibly deserve 

 to be considered as sub-species ; one occurs near Grand Havre, 

 Guernsey, on Leontodon autumnale, which has the corolla curved 

 like 0. amethystea, but a much shorter and denser spike, and the 

 whole plant, including the flowers, is yellow. 



Another form, which occurs about Epsom and Leatherhead, at 

 Sowerby, near Thirsk, Yorkshire, and near Pangbourne, Berks, is 

 a much larger plant than the ordinary O. minor, often 2 feet high, 

 with the corolla more curved, the curvature greatest near the 

 middle ; the lips much longer in proportion, and the middle seg- 

 ment of the lower lip conspicuously larger than the others. 



Bluish Broom-rape. 

 French, Orobanche du Panicaut. Germau, Amethystfarbene Soinmerwurz.
