THE GENUS CAMPANULA FROM A GARDENER'S POINT OF VIEW. 33 
belled macrantha ; and ccBspitosa, with its free habit and 
pleasing leaves, as well as its abundance of flowers, has posses- 
sion of a broad piece of the bank, and has rapidly encircled 
many of the big boulders. There are Ferns, both large and small, 
but these Campanulas by the waterside run around them ; for- 
bidden by the darkness or the shadow of the spreading fronds, 
they have simply accommodated themselves by turning in other 
directions, and they seem grateful that they may ramble else- 
where. 
By the edges of the walk on both sides, and delightfully 
creeping into the gravel, are large masses of C. pusilla in various 
shades of colour, but, of course, including the white form. Allioni, 
a pigmy plant with giant flowers and bells erect, occupies a 
similar place. The pretty garganica, with its racemes of starry 
flowers — procumbent — and with each flower suggesting a white 
star in a blue foil, forms itself into charmingly rounded tufts, 
the centre cushions of delicate green being surrounded with a 
ring of starry inflorescence. In no case do these humble Bell- 
worts occur in line, but, on the contrary, break up the essentially 
line-character of the walk. Unless you watch your feet, you 
may tread on pretty tufts of mollis and muralis. Bulla you may 
easily overlook, as its herbage is so thin and scarcely con- 
spicuous when not in flower ; then, however, you cannot miss 
it, for its comparatively large black-purple bells almost invite you 
to kneel down and closely examine and admire them. 
Here and there near the walk are more of these humble 
beauties, such as Waldsteiniana, with its hair-like stems, almost 
leading you to suppose that its sheeny bells are without supports. 
In the shght gutter on the walk side, and evidently loving the 
gravel, is the rare grey-foliaged Baineri, with erect cup-like 
flowers of a delicate heliotrope hue. In the warmer soil, by 
reason of its mixture with the gravel, is Porte^ischlageana, which 
in fatter soil might not delight you with its perennial appearance. 
There you see a deep green and shining mass of overlapping 
and somewhat rosetted cushions of foliage, with dumpy and 
stout, but very short flower-stems. That is surely the typical 
nitida, and by its side, of a paler green, and evidently not so 
robust, is its ivhite form. In passing let me say this is one of 
the most exquisite of the dwarf Bellworts, and all too rare. 
Seldom are its flowers borne above 4 or 5 inches high : they
