Parthenocissus, which will probably have difficulty in getting • 
adopted amongst admirers of the Virginian Creeper. _ A 
very distinct-looking species has been introduced from China 
under the name of Ampelopsis cantoniensis, with ternately 
divided leaves. 
The species of Prunus are well represented, and include 
several that might be more extensively cultivated for the 
sake of the beautiful contrast between their grey foliage and 
the green leaves of neighbouring plants. Amongst these we 
m io-ht mention P. incana, P. tomentosa, and P. canescens. The 
young shoots and foliage of the last named are of a very 
decided velvety-grey. It is also a new introduction from Se 
Tchuen. The species of Spiraea are also extremely numerous, 
and include a considerable number of hybrids. The Brambles 
are also represented by a much larger number of species than 
one usually finds in private gardens. 
The Roses, however, are much more numerous than the 
Brambles, and have the convenience of being arranged in 
groups or sections, apparently those drawn up and published 
by the late M. Crepin. A number of them are hybrids, either 
artificial or natural. Amongst the little known introductions 
is that named R. soulieana, and described by the last named 
author. The flowers are produced in large trusses, and the 
species belongs to the same group as the Polyantha Rose, the 
Musk Rose, and the British Field Rose, including the Ayrshire 
Boses here listed under the name of R. arvensis ayreshirea. 
This new species is evidently very floriferous, and would make 
an interesting garden Rose. It comes from China, and has 
white flowers, followed by small orange fruits in the autumn. 
It also blooms relatively late in the year, and would thus 
furnish a succession. 
A woodcut of R. macrophylla also snows a wild Rose of 
beautiful habit with very large lively red flowers, followed 
by bottle-shaped fruits of remarkable length and handsome 
appearance. The variety R.m. rubro-staminea is characterised 
by orange-coloured anthers. The variety is new, though the 
species itself was described by Dr. Lindley. R. minutifolia 
is evidently a peculiar species with small, deeply-cut leaves 
and bristly outgrowths under the flower. The foliage recalls 
Berberis coneinna. 
Amongst the Honeysuckles is one which would prove a 
desirable advantage in a collection of shrubs. The flowers 
are of large size, rosy-lilac, and give off a sweet scent, recall¬ 
ing that of the Lilac. The plant forms a bushy shrub about 
a yard in height and as far through. This is Lonicera 
thibetica, and comes.from a place in Thibet between Lhassa 
and Batang. For many years past w'e have been receiving 
new species and hybrids of Deutzia and Philadelphus from 
France. A new species, named Deutzia Vilmorinae, has white 
flowers about 1 in. in diameter. It forms a. bush about 
6 ft. to 7 ft. high, and comes from Se Tchuen in China. The 
list of Deutzias is now a fairly lengthy one, including species 
recently introduced from China, and hybrids. Another new 
species is D. sutchueuensis., This latter, however, is not very 
hardy, and is recommended for districts in the West or South¬ 
west of France. 
Another interesting shrub is that named Osmanthus Dela- 
vayi, discovered and sent home by Abbe Delavay from 
Yunnan. This forms a dwarf shrub with elliptic evergreen 
leaves of a leathery character and large pure white flowers 
produced in trusses terminating the branches. They are also 
sweet scented. So far as we know the species of Osmanthus 
in this country, the flowers are very small by comparison with 
this one. The author recommends it as a small shrub for 
rockeries in the West and South-west, 
It is simply impossible to name all of the new, recent, or 
interesting things in this immense list, but no doubt it will 
find its way into the hands of most people interested in a 
class, of plants which contributes to the embellishment of 
every garden of any importance.

Clivias. 
Clivias or Imantophyllums are very convenient plants at 
any time of the year. When flowering they look magnificent; 
when out of flower their foliage, which, under ordinary treat¬ 
ment, is always of a healthy green, gives them the advantage 
of always being desirable for some corner of the intermediate 
house or greenhouse. A structure which enables a minimum 
temperature of 50 deg. during the winter is probably the best 
for this particular plant. 
The varieties of Clivia miniata are first in excellence 
against all other types in their beauty. The flowers, measur¬ 
ing 2 in. or 3 in. in diameter, and borne in umbels on stout 
erect scapes, held well above the foliage, exhibit themselves 
to perfection. The various shades of colour, too, are excel¬ 
lent, varying from deep to pale orange. 
They are remarkably easy to grow', either when planted out 
or in pots. In the latter they do not require to be potted 
often, but are better to be left for several years in the same 
pots, and .furnished with abundance of manure in liquid form. 
When repotting care should be taken not to break the roots. 
These, being thick and fleshy, are not so easily replaced as in 
the case of fibrous-rooted subjects. Except in the case of 
plants that are showing flowers, the present is the best time 
to repot or top-dress. Those coming into bloom may be 
shifted on immediately after the flowers are past. 
Any good soil, with good fibrous loam as base, and having 
porosity, is suitable for Clivias. Being excessive feeders a 
quantity of ground bones should be distributed through the 
compost, which will exert some influence in producing large 
flowers. 
Single-crowned plants in 6-in. pots are very handy. For 
this purpose seedlings are easily got up, and acquire size to 
flower in about three years. Seeds should be sown in heat, 
and the young plants grown in the intermediate house. 
With the low temperature in winter water should be with¬ 
held from them to some extent, but when growing they re¬ 
quire abundance. They like shade, and do not object to much 
“ kicking about.” I have seen huge plants which, although 
standing beside the path in a corridor, and subject to much 
ill-use from passers-by, flowered very profusely every year all 
the same, and small plants likewise! When grown in the 
stove Clivias make beautiful foliage, but are apt to be very 
miserly in giving flowers. James P. Dickson. 
Renovating Old Shrubberies. 
In gardens where this department is well cared for, each 
shrub, or group of shrubs, gets a certain amount of attention 
every year, rendering the above process unnecessary. This is 
not the case in the majority of gardens. Want of knowledge 
and training on the part of the gardener, the fact that a good 
many shrubs and trees are not of his planting, and the idea 
that their well-doing will bring credit to his predecessor rather 
than to him, may account for this in some cases. Too often, 
however, the amount of labour at his command, and the ex¬ 
pressed wishes of his employer—who. much as he may love 
his trees and shrubs, knows little of their needs until too late— 
lead him, the gardener, to aim at success in those subjects 
giving quick returns, rather than permanent effects. The 
craze for bedding out and exhibiting has. led to the neglect 
of many shrubberies. Where such is the case, determine at 
once that it shall not continue; use your influence to 
obtain proper recognition for this important department of the 
garden. Form a plan of action, note the strong features of 
the garden—the best views, the noblest trees, and most beauti¬ 
ful groups, and choicest shrubs. Preserve and improve these 
—in the first case by cutting out the obstructing branches, or 
even removing one or more trees. 
When specimen trees are growing old, and showing signs of 
exhaustion, a heavy top-dressing of soil mixed with a small 
proportion of manure will often give them a new lease of 
life. Ten years ago a fine old specimen of Pinus excelsea on 
the lawn here was in a very bad state of health. About the
