in collections. Hardly less beautiful and interesting is the 
single form which, when seen growing wild in grassy places, 
is certainly attractive and one of the most conspicuous plants 
amongst the short) grass in chalk districts where it grows. 
The petals in the single form drop more quickly than those of 
the double variety; otherwise I should give it preference for 
planting on the rockery or in the border, owing to its more 
graceful appearance. The flowers are creamy-white in both 
cases, more decidedly white, in fact, than in the case of the 
Meadow Sweet. Propagation is easily effected by separation 
of crowns towards the end of September or again in March. 
The tuberous droppers from which the plant takes its name 
should be left on the pieces taken off if possible. 
Platycodon grandiflorum Mariesii. 
There are several varieties of the species, both single and 
double, with a variety of colours, chiefly in some shade of blue 
or white, but for the alpine garden none of them is more 
suitable than the variety above named. It. is. of dwarf habit, 
seldom exceeding 6 in. in height, but flowers as freely as the 
ordinary form, the flowers being much the same, both in size 
and colour. It should be exposed to light and air, and Ts not 
at all particular if placed in a. somewhat dry position, provided 
the soil is fairly deep, so that its roots can descend. 
Campanula waldsteiniana. 
At the present time there is no better nor truly alpine blue 
flower than the species just named. It is a true inhabitant of 
the rocks, producing stems 3 in. to 6 in. in height, covered on 
the top with small lilac-blue flowers, with a very much darker 
centre. The leaves are lanceolate and clothe the stems thickly. 
The plant itself is tufted, the stems ascending in great numbers 
and in close proximity, so that even if of small size it is very 
attractive at this season of the year when in full bloom. It 
is veiy difficult to get cuttings of this species that would be 
likely to root, but an outlook should be- kept for seeds, a.s the 
species is well worthy of a. little care in raising plants by this 
means. A sharp outlook will have to be kept for slugs, which 
are very fond of small plants. 
Oenothera caespitosa. 
Various names have been given to the above dwarf and beau¬ 
tiful species of evening Primrose, including Oe. marginata, Oe. 
eximia, Oe. saxosa, and Oe. caulescens. Strong plants may 
develop stems 6 in. in length, but as a rule they are shorter, 
rather stout, well furnished with spathulate and toothed leaves. 
The flowers are of large size even for an evening Primrose, but 
they are unusually large for a plant of such small dimensions. 
Like other species of Oenothera, they are rather short-lived, but 
develop fresh flowers in succession, and at first, are pure white, 
but gradually fade to pink. The crown or rootstock grows 
slowly, but if a large batch of it is desired a number of plants 
could be inserted in the rockwork about 6 in. or 9 in. apart. 
By this means a clump of any size desired could be produced, 
and a succession of flowers would be ensured, as some or other 
of the plants would be sure to- have.one or more flowers op>en. 
Beeds of this species should be secured if it. is desired to in¬ 
crease the number, and to make sure of this ,tlie flowers might 
be fertilised artificially. Cuttings may, of course, be taken off 
and rooted in sandy soil ill a cold frame at this season of the 
year. Propagation by this, method is, of course, rather a. slow 
process, so that, raising young plants from seeds is desirable. 
A rather dry situation fully exposed to- sunshine! should be 
selected for the plant, and a. damp situation avoided, par¬ 
ticularly in winter. 
Geranium sanguineum lancastriense. 
The ordinary form of G. sanguineum is a. native of rocky 
and sandy places on the seashore. That also applies to the 
beautiful variety under notice, which is confined to an island 
off the coast- of Lancashire, or was originally found there. The 
flowers of this beautiful variety are of the palest pink, but 
thickly covered with rosy veins and very pretty. Only one 
flower is produced on a stalk, and in this respect the two- forms 
differ from all our other native Geraniums. Some cultivators 
are not particularly fond of the ordinary red form, but the 
variety under notice is a distinct break, and certainly worthy 
of more extended cultivation. 
Campanula carpatica pelviformis. 
For some years past there have been many good varieties 
of C. carpatica in cultivation, including hybrids between it and 
the other distinct form known as C. turbinata. Of all the- 
forms that have- been raised, however, few if any of them are 
so distinct in form as C. c. pelviformis,. the flowers of which 
are saucer-shaped or - nearly flat, and of a pale lavender hue. 
The stems themselves- are rather tufted and more upright 
than in the ordinary C. carpatica, and therefore I consider it 
better for the rock garden than the- last-named, which in damp 
districts or seasons often requires staking when planted in rich 
soil. The variety unde-r notice can be increased by means of 
cuttings that have not flowered, placing them in very s-andy 
soil and keeping the pots under a handlight in a cold frame. 
Dianthus deltoides. 
The procumbent stems of this species and the brightly 
coloured flowers make it suitable- for rockwork. At present it 
is ve-ry handsome where it grows in the wild state in sandy 
Allium kansuense. (Seep. 675.) 
soils, generally amongst grass. The flowe-rs are of a. bright 
rose-, with white- markings round the eye, but sometimes a 
white variety turns- up amongst the others. The leave-s are 
dark green, and in that respect differ from the glaucous hue 
of the Pinks that usually grow upon rocks and walls. The 
Maiden Pink is readily propagated from seed, so that there is 
no- necessity for taking cuttings, provided the plants have 
bloomed and set seeds, which they usually do. 
Geranium argenteum. 
Few of the- Geraniums are of neater growth than this species, 
which 'co-mes from the Alps. The leaves themselves are very 
pretty, and remind us of Alchemilla alpina, though not quite so 
finely divided. They are- really five to seven lobe-d, and the 
larger ones again trifid. The whole surface is of a beautiful 
silvery gray appearance. The flowers are of large size and 
lilac, beautifully feathered with purple veins.. The whole plant 
is only 6 in. high, so that- it is very well adapted for the ro-ck 
garden, where it may be planted even in small pockets or
