BRITISH WILD FLOWERS. 
GENUS XVI. 
WHITE HOREHOUND. (Marrubium, Lin.) 
Lin. Syst. DIDYNAMIA GYMNOSPERMIA. 
Generic Character.— Calyx-teeth ten, bristle-shaped, hooked backwards. Leaves roundish-ovate, unequally serrated. (Smith.) 
Description, &c. —The White Horehound (M. vulgare , Lin.) is well known as a remedy for coughs, and 
it is generally taken for that purpose, notwithstanding its very disagreeable taste. The flowers, which appear 
about September, are small, and of a yellowish-white; and the stem and leaves are covered with a thick white 
wool. The plant grows abundantly on rubbish by the road-sides, and in other dry places. The name of 
Marrubium is derived from a Hebrew word signifying a bitter juice. 
GENUS XVII. 
THE SKULLCAP. (Scutellaria, Lire.) 
Lin. Syst. DIDYNAMIA GYMNOSPERMIA. 
Generic Character. —Calyx short, with both lips entire ; a concave scale lying on the upper lip. Corolla longer, curved at the base ; 
limb bilabiate. ( Lindley.) 
Description, &c. —There are only two British species of this genus, and neither of them can be considered 
ornamental. The common Skullcap (S. galericulata, Lin.) has small blue flowers, and grows on the banks of 
rivers, and other moist places, preferring a gravelly soil. The other species (S. minor , Lin.) is less common, 
and the flowers are pink. Both species flower in July and August, and both are perennials. 
GENUS XVIII. 
SELF-HEAL. (Prunella, Lin.) 
Lin. Syst. DIDYNAMIA GYMNOSPERMIA. 
Generic Character, —Calyx bi-labiate ; the upper lip flat, some- j being larger than the rest and emarginate. Filaments bearing a naked 
what truncate, with three very short teeth ; the lower bifid. Corolla tooth below the anther. (Lindley.) 
with the upper lip concave; the lower three lobed ; the middle lobe 
Description, &c. —There is only one British species of this genus, viz., the common Self-heal (P. vulgaris, 
Lin.), which is abundant in meadows. It is a plant of no beauty, with purple flowers, which appear in June 
and July. It was formerly much esteemed as a remedy for sore throats, and hence, it is said, arises its generic 
name ; which was originally Brunella, and derived from the German word braiine, signifying the Quinsy. The 
plant is a perennial. 
The flowers of all the plants hitherto described have had a distinct calyx and corolla, and have belonged to the 
Dichlamydese, a word which signifies two coverings; those plants which remain to be described have only one 
covering to the stamens and pistil, and are therefore called Monoclilamydeae. Many of the orders in this division 
contain no plants having ornamental flowers, and will therefore bo omitted. Among these may be mentioned
