2—CHRYSANTHEMUM VISCOSUM, Desf. THE CLAMMY CHRYSANTHEMUM. 
Synonymfs. —Centrospcrmmn Chrysanthemum, Spren. ; Heter- 
anthemis viscido-hirta, Schott; Pinordia anisocephala, Cass. 
Specific Character. —Plant covered with clammy down. Leaves 
rather fleshy ; lower ones half stem-clasping, oblong, somewhat pinna- 
tifid ; upper ones cordately stem-clasping, toothed ; each tooth ter¬ 
minated by an acute rigid point. Heads terminal, solitary. 
Description, &c. —A native of the south of Spain, and also of the sandy plains near Algiers. It is a dwarf 
plant with heads of yellow flowers, introduced in 1823. The seeds may be purchased at Charlwood’s ; and they 
should be sown in March or April, in a warm dry border, and rather sandy soil. Its common name in the seed- 
shops is Centrospermum Chrysanthemum ; Centrospermum signifying a spur-shaped seed. 
3 .— CHRYSANTHEMUM CORONARIUM, Lin. THE GARLAND-FLOWERED CHRYSANTHEMUM. 
Leaves auriculately stem-clasping, bipinnatifid ; lobes lanceolate, 
dilated at the apex, deeply serrated. Scales of involucrum scarious 
at the apex. 
Description, &c.— There are several varieties of this species grown in gardens ; the double white, the yellow, 
and the quilled, are, however, the most common. They are all ornamental, from the great profusion of their 
flowers, which make the plants of the white variety almost like bushes covered with clusters of large double- 
flowered cherry blossoms. The species is a native of the south of Europe, and north of Africa; and it was 
introduced before 1629. The seeds are common in all the seed-shops ; and they may either be sown in the open 
border in April or May, or raised on a slight hot-bed, and planted out in the latter month. They should, in 
fact, be treated like the French marigold ; but will require staking and tying up. This and all the common 
plants which have been for many years raised every season on slight liot-beds, may be grown equally well in the 
open border, by watering them every morning with warm water; and turning a flower-pot over them during 
cold nights, while they are yet young. 
Synonyme. —Chrysanthemum segetum, Forsk. ; Matricaria coro- 
naria, Desr. 
Specific Character. —Glabrous. Stem erect, diffused, branched. 
4— CHRYSANTHEMUM ROXBURGHJI, Desf. DR. ROXBURGH’S CHRYSANTHEMUM, OR THE 
EAST INDIAN FEVERFEW. 
Synonymfs. —Pyrethrum indicum, Roxb.; Glebionis Roxburghii, 
Cass.; Chrysanthemum senecoides, Dunal. ; Matricaria oleracea, 
Ham. ; Pinordia Roxburghii, Less. 
Engraving. —Bot. Mag. t. 1521. 
Specific Character.- —Glabrous. Stem erect, cylindrical, branched. 
Leaves auriculately stem-clasping, pinnatifid. Lobes entire or toothed. 
Involucrum campanulate, having the inner scales each drawn out into 
a roundish scarious appendage. 
Varieties. —C. R. 2 breviradiatum, Dec. ; C. breviradiatum, 
Ledebour. ; Flowers with a short ray. Introduced in 1818. 
C. R. 3 radiatum, Dec. ; flowers with a long ray. 
Description, &c.— The species is a very singular flower with no disk, well known in our gardens under the 
name of Pyrethrum indicum. It is a native of the East Indies ; whence the seeds were sent by Dr. Roxburgh to 
Mr. Lambert in 1810. Seeds may be purchased in any of the seed-shops, under the name of Pyrethrum 
indicum. The culture of the plant is the same as that of C. coronarium , except that it does not require either 
staking or tying up. 
5.—CHRYSANTHEMUM SEGETUM, Lin. THE CORN MARIGOLD OR YELLOW OX-EYE. 
Synonymfs.- —Pyrethrum segetum, Moench. 
Engravings. —Eng. Bot. t. 540, 2nd. edit. vol. 6, t. 1172. 
Specific Character. — Glabrous. Stem erect, branched. Leaves 
stem-clasping; some coarsely serrated, others laciniated. Branches 
naked near the apex, one-headed. Scales of the involucrum obtuse at 
the apex, and scarious. 
Description, &c. —If this beautiful flower were rare, and difficult to be cultivated, it would be highly 
valued ; but being a common English weed, few persons notice it except the farmers, and they wage war against 
it. It is particularly abundant in corn-fields, where the soil is sandy ; and in such situations, it is very difficult
