are slightly fragrant ; the stem grows from one foot to two feet high. It was supposed at first to be a native of 
China, but it is now said to be from Siberia. It waa introduced in 1789. It is generally propagated by 
dividing the roots. 
2.— SENECIO VENUSTUS Willd. THE HANDSOME SENECIO. 
Engraviko. — Bot. Reg. t. 901. 
Specific Character. — Flowers radiant. The whole plant glabrous. Leaves pinnatiiid ; segments linear, acute. 
Description, &c. — This very handsome species, though generally called a perennial, seldom lives more than 
three or four years, and frequently dies as soon as it has flowered, and ripened its seed. It is nearly related to 
the purple Jacoboea of the gardens, but the leaves are much more finely cut. It is a native of the Cape of Good 
Hope, whence it was introduced in 177-4. 
THE FLASK-FLOWERED AMERICAN GROUNDSEL. 
Panicle of flowers corymbose. Involucre flask-shaped, naked. Flowers 
of the ray few, spreading. Achenium cylindrical, attenuated towards 
the apex, furnished with a long, silky-pubescent pappus. 
3 SENECIO AMPULLACEUS, Lindl. 
Engraving Bot. Reg. t, 3487. 
Specific Character.— Herbaceous, erect, very smooth, striated. 
Leaves oblong, obtuse, fleshy, somewhat stem-clasping at the base. 
Description, &c. — A very handsome plant, with showy golden-yellow flowers ; the leaves are peculiarly thick 
and fleshy, with a pinkish midrib; the stem is also pinkish. The seeds are easily known by the abundance of their 
white silky pappus. There are many other handsome species of Senecio, but they are generally too tender to be 
grown in the open ground without great care. 
GENUS XXV. 
ARNICA, Lin. THE ARNICA. 
Lin. Sijsl. SYNGENESIA SUPERFLUA. 
GiMsnic Charactdr. — Receptacle naked. Pappus simple. Scales of the involucre equal. Florets of the ray narrow, spreading ; many times 
longer than those of the disk. 
Description, &c. — The plants contained in the genus Arnica were separated by Linnaeus from Doronicum, 
or Leopard's- bane. The word Arnica is said to be derived from a Greek word, signifying a lamb's skin, in 
allusion to the wooUiness of the leaves.

Engravings. — Bot. Mag. 1749 ; and ouv Jig. 5, in Plate 54. 
Description, &c. — This is a very showy plant, which, if grown in a moist, shady situation, will attain a 
large size, and produce great abundance of its brilliant yellow flowers. It was formerly in high repute for its 
medicinal properties ; and, as it is said to clear the head by exciting sneezing when reduced to powder, it was 
called Mountain Snufi^. It is now seldom grown, though it would be a very useful plant for shrubberies. It is a 
native of Germany, and other parts of middle Europe, whence it was introduced in 1731. 
There are several other species of Arnica, all of which are hardy perennials, but they are seldom grown in 
gardens.
