time, however, it was discovered that it succeeded much better when treated as a greenhouse perennial, as when 
grown in the open border it would never flower well unless the weather was warm and dry, being easily injured | 
by wet and very apt to damp off. This plant varies very much, and the flowers are of every shade of blue and | 
lustrous lilac, with considerable diversity in the size and shape of the flower heads.

Essentian Cuaracter.—Calyx superior, usually five-lobed, per- | covered with collecting hairs. Stigma naked, simple, or with as many 
sistent. Corolla monopetalous, regular, permanent, usually five-lobed, | lobes as there are cells. Fruit dry, crowned by the withered calyx and 
inserted in the top of the calyx. Stamens five, inserted in the calyx | corolla, always loculicidal. Seeds numerous, attached to a placenta 
alternately with the lobes of the corolla. Anthers two-celled, distinct. | in the axis. | 
Ovary inferior, with two or more polyspermous cells. Style simple, 

Description, &c.—The plants belonging to this order are all either herbaceous or suffruticose, and they all 
abound with a somewhat acrid milky juice. The flowers are ornamental, but nine-tenths of them are blue. The 
order was formerly combined with Lobeliacee, but the two orders differ in their botanical construction, particularly 
in the very short filaments of the stamens of the Campanulacee, and in the style being furnished with collecting 
hairs, which appear intended to clear out the pollen from the cells of the anthers. These collecting hairs appear 

much longer when the flower is in the bud or just opened than they do afterwards when it has been long expanded, 

and as they finally disappear, it was supposed that they were deciduous, but it is now found they possess a curious 
retractile power like the tentacula, or horns of the snail, and that when they have performed their office of | 
collecting the pollen, they are gradually drawn back into certain cavities lying at their base. Most of the genera 
included in this order contain only hardy plants. 
GENUS I. 
CANARINA Juss. THE CANARINA. 
Lin, Syst. HEXANDRIA MONOGYNIA. 
Generic Cuaracter.—Calyx and corolla six-lobed. Stamens six. Stigmas six. Cells of the fruit opposite the stamens and calyeine | 
segments. (G Don.) 

Description, &c.—There are only two species in this genus, and one of them is a stove-plant. The 
greenhouse Canarina was formerly included in the genus Campanula, and when it was separated on account of 
t

| 
the difference in the number of stamens and some other particulars, the new genus was called Canarina, | | 
from this plant being a native of the Canary Islands.
