tube of the corolla. Anthers bilocular, and the filaments are 
flattened and enlarged in their lower part in order that they may 
embrace the ovary. The pistil is composed of an inferior ovary, 
surmounted by a style, divided into five stigmatic branches. The 
ovary is five-celled. The fruit a capsule, which opens at the base 
in five small cells. 
There are several species of the Campanula which are only culti- 
vated for their pretty flowers and pyramidal form. We may cite, 
as worthy of cultivation in the garden, the Peach-leaved Bell- 
flower (C. persicifolia), with flowers of pale blue, erect and in long 
compound panicles, indigenous in Kent and the south of England 
and in France. This species grows double, and forms a fine 
garden flower. C. pyramidalis is another stately Bell-flower — 
which reaches the height of three or four feet, forming a pyramidal 
mass of flower. The pretty Scotch Harebell (C. rotundifolia), with 
slender stem and nodding cluster of “heavenly blue,” is not the 
least worthy of notice. 
The Loseniacem are frequently found within or upon the 
borders of the tropics of both hemispheres. They are rare in 
northern parts ; Spain, Sicily, and Italy, each claim one, and one , 
is found in Kamtschatka. They are extremely beautiful when in 
blossom, and great favourites in the greenhouse, but the milky 
juice with which they are charged is powerfully acrid and narcotic, 
corrodes the skin, and is fatal taken internally. Burton says that 
if horses eat L. longiflora, inflammation is produced, so that they ie 
swell until they burst. Like most of the poisonous orders, it m- 
cludes species possessing valuable medicinal properties. Many © 
them yield gums and oils. The Lobeliads are found chiefly between | 
the tropics in the New World; in Asia and Africa they are found yy : 
to the south of these regions, some few in North America, and one 
in Kamtschatka, They are all charged with a milky juice which 
is sufficiently acrid to corrode the skin, mingling with narcotic 
properties of a dangerous character. The Indian tobacco (L. inflata) 
is a North American species, possessed of medicinal virtues.
