OP ORNAMENTAL PERENNIALS. 5 
It is a native of North America, where it is generally found on the banks of rivers. It was introduced in 1767. 
It is hardy in British gardens, but is very seldom seen, as it does not ripen seeds in this country, and it is 
generally killed by any attempt to divide the root. The flowers are without fragrance. 
C. ERECTA All. 
This species has white, sweet-scented flowers, and pinnate leaves. The flowers are produced in dense 
corymbs, and the plant grows two or three feet high. There are several varieties, which do not, however, difiFer 
greatly from the species. This species is sometimes called the Spanish Virgin's Bower, and it is found wild in 
Spain, and throughout the south of Europe. It was introduced before 1597, but it is seldom seen in British 
pardens. It flowers from June till August. 
C. MARITIMA Lin. 
This species differs from the preceding one, chiefly in the corymbs of flowers being loose instead of dense. It 
is a native of the south of Europe, where it is generally found on the sea-coast. 
C. ANGUSTIFOLIA Jacq.; Wat. Dend. Brit. t.\\2; 
has white flowers, with very blunt sepals. The leaves are pinnate, and the leaflets lanceolate. It is a native of 
Siberia, and was introduced in 1787. 
There are two or three other species which may be called herbaceous when young, but they most of them 
take a half shrubby character with time. 
GENUS II. 
THALICTRUM Ltn. THE MEADOW RUE, OR FEATHERY COLUMBINE. 
Lin. Syst. POLYANDRIA POLYGYNIA. 
GuNEaic Character. — Involucre none. Calyx of four or five de- | terminated by a point. Seeds pendulous. Stems never climbiug. 
eiduous sepals. Carpels I-seeded, indohisceut, frequently stalked, | Leaves alternate. 
Description, &c. — The flowers of plants of this genus have no petals; and, though they have a calyx of 
four or five petal-like sepals, it is generally so small and inconspicuous, and falls so soon, that the flowers appear 
to be all stamens. The carpels are caryopsides, terminating in a point ; the roots are perennial ; but the stems 
die down to the ground every winter.' The roots have an unpleasant smell, and resemble those of rhubarb, both 
in appearance and qualities. The British species are called Meadow Eue, from their leaves having the taste of 
rue ; but their flowers can hardly be called ornamental. Only two or three species are cultivated in British 
gardens. The name of Thalktrum is derived from a Greek word, to grow green, from tlie bright green of the 
young shoots ; or from two Greek words, signifying the " cradle of affluence," from the abundance of its flowers.
