pilasters and columns of the Corinthian order in antis, and central
turret with spire above. In Genoa there are many examples; the quoins
are either decorated with rusticated masonry or attenuated pilasters,
with or without horizontal string-courses, always crowned with a belfry
storey in stone and classic cornices, which on account of their greater
projection present a fine effect. (R. P. S.)

CAMPANULA (Bell-flower), in botany, a genus of plants containing about
230 species, found in the temperate parts of the northern hemisphere,
chiefly in the Mediterranean region. The name is taken from the
bell-shaped flower. The plants are perennial, rarely annual or biennial,
herbs with spikes or racemes of white, blue or lilac flowers. Several
are native in Britain; _Campanula rotundifolia_ is the harebell (q.v.)
or Scotch bluebell, a common plant on pastures and heaths,--the delicate
slender stem bears one or a few drooping bell-shaped flowers; _C.
Rapunculus_, rampion or ramps, is a larger plant with a panicle of
broadly campanulate red-purple or blue flowers, and occurs on gravelly
roadsides and hedgebanks, but is rare. It is cultivated, but not
extensively, for its fleshy roots, which are used, either boiled or raw,
as salad. Many of the species are grown in gardens for their elegant
flowers; the dwarf forms are excellent for pot culture, rockeries or
fronts of borders. _C. Medium_, Canterbury bell, with large blue, purple
and white flowers, is a favourite and handsome biennial, of which there
are numerous varieties. _C. persicifolia_, a perennial with more open
flowers, is also a well-known border plant, with numerous forms,
including white and blue-flowered and single and double. _C. glomerata_,
which has sessile flowers crowded in heads on the stems and branches,
found native in Britain in chalky and dry pastures, is known in numerous
varieties as a border plant. _C. pyramidalis_, with numerous flowers
forming a tall pyramidal inflorescence, is a handsome species. There are
also a number of alpine species suitable for rockeries, such as _C.
alpina, caucasica, caespitosa_ and others. The plants are easily
cultivated. The perennials are propagated by dividing the roots or by
young cuttings in spring, or by seeds.
