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 West, where York and Hereford 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 f 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.

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 Eiyngium 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 O. 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 O. arnethystea, 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. German, Amethyslfarlene Sommerwurz.
