THE CLOVE-SCENTED BROOM-RAPE. (O. caryophyllacea, Smith.) 
This is a more ornamental plant than the common species, as its flowers, which appear in August, are of a 
pale purple, with very distinct dark veins. It has only been found in Kent, Sussex, and Devonshire, and it was 
first discovered growing on the roots of the Larger Bed-straw. 
THE TALL BROOM-RAPE. (O. elatior, Sutton.) 
This species is generally found on Centaurea Scabiosa. The flowers are of a pale pink, and the stem, which 
is very thick, is of a brownish yellow. The flowers appear in July and August. 
THE LESSER BROOM-RAPE. (O. minor, Smith.) 
This is a very elegant plant, though it is a very destructive one, as it generally attacks the roots of the 
common red Clover, and will sometimes destroy nearly a whole field. Both the flowers and stem are of a 
lavender colour. 
THE RED FRAGRANT BROOM-RAPE. (O. rubra, Smith.) 
This species is a dark brownish red, and the flowers, which have a fragrance like that of the Honeysuckle, 
appear in July. It is generally found on the roots of the Wild Thyme. 
** Bracteas three to each flower.

v Description, &c. —This is a rare species, which is seldom found except in Norfolk. It generally attaches 
itself to the roots of the common Wormwood, or to the Sea Southernwood. It flowers in July. 
THE BRANCHED BROOM-RAPE. (O. ramosa, Lin.) 
This is the most curious plant of the genus, as it is the only one which has a branched stem. It is generally 
found attached to the roots of hemp in moist rich soil, and it is most common in Norfolk and Suffolk. The stem 
is yellowish, with a conspicuous brown bulb at the base. The flowers are of a pale purple, or yellowish, and 
they appear in August and September. 
GENUS II. 
THE TOOTH-WORT. (Latkulea, Lin.) 
Lin. Syst. DIDYNAMIA ANGIOSPERMIA. 
Generic Character. —Calyx campanulate, four-cleft. Corolla tubular, two-lipped ; the upper lip galeate. Stamens four, didynamous. 
Ovarium surrounded by a disk at the base. Style one. Stigma two-lobed. ( Lindley .) 
Description, &c. —This genus contains only one British plant. The name of Lathrcea is derived from a 
Greek word signifying hid or concealed, because the plant is generally found almost buried in decayed leaves.
