IVIES AT CHISWICK. 
{Continued fyom page 594-) 
Leaves tricuspidate. 
Chrysomela.— The leaves of this variety are broad 
and shallowly three-lobed or tricuspidate. When 
they first expand they are of a pleasing light 
yellowish-green, and many of them are more or 
less wholly of a bright golden-yellow. This hue 
they retain till about midsummer, when they become 
bright green or variously splashed with gold It is 
the best of all the golden varieties, and appears to 
be a sport from Angularis, or is closely allied to it, 
judging from the form of the leaf. 
Leaves three-angled. 
The usual form of the leaves of this group is 
triangular, the angles not being deep enough to be 
considered lobes. Occasionally a large leaf is five¬ 
angled, but it is exceptional. All of them may be 
considered as small forms of the common Ivy, and a 
large number of them possess a silvery margin or 
variegation. Many of them are indeed forms of 
Marginata, while many others are a mere multiplica¬ 
tion of names for the same thing. 
Marginata.— The growth of this variety is 
moderately vigorous, and it forms a beautiful 
covering to a wall, more especially in autumn, when 
the bluntly triangular leaves are of a grayish-green 
with a silvery margin, and more or less striped with 
some shade of red. At present we find it impossible 
owing to the small size of the plants and their present 
condition to distinguish the specimens under the 
names of Marginata media. Best Marginata, and 
Marginata Argentea. A plant named Arborescens 
variegata has lost its tree habit, and is merely the 
ordinary climbing Marginata. 
Marginata rubra. —In addition to the broad 
silvery margin of the leaves of this beautiful variety, 
the edge assumes a rosy-red hue in the autumn, but 
loses it again in spring. The young leaves have a 
greenish-yellow margin. The complication of names 
is here again very great. Marginata purpurea, 
Marginata elegantissima, and Marginata robusta 
appear to be merely synonyms, while by a trans¬ 
position of names we get another series such as 
Elegantissima marginata rubra, and Elegantissima 
marginata grandis. Elegantissima and Tricolor are 
recorded as synonyms of Marginata rubra. There 
can be little doubt that there is a great mixture 
of names all applied to a popular plant, and forgotten 
or added to as occasion may serve. 
Elegantissima.— This is a name applied to one 
of the forms of Marginata, but at present it is 
difficult to say which. The leaves are moderately 
large, triangular, pale green with a creamy margin 
when newly developed, but ultimately becoming 
washed with gray all over and having a broad 
silver margin. The old leaves are retained in good 
condition till sometime after the production of the 
new ones. The variety is readily distinguished from 
Marginata rubra by its larger leaves and their creamy 
white margins when newly developed. Under this 
we must place a plant named Lacteola for the 
present. 
Margin.ata major.— Whether this is really 
different from Marginata must be determined when 
the plant gets strong. 
Marginata minor — The leaves of this variety 
are very small, and triangular or shallowly three- 
lobed or sub-hastate, with a clear silvery margin 
tinted with red at the extreme edge ; ultimately, 
they become washed with gray all over. The plant 
is of very slow growth and apparently not well 
adapted for culture on open walls, but would be 
more suitable for pot work. Small and not very 
healthy plants under the names of Aurea elegan¬ 
tissima and Marginata purpurea are evidently the 
same thing. The former of the two names is also 
applied to a strong growing and altogether different 
Ivy. 
Lee’s New Silver.— This is evidently one of 
the Marginata group, but is quite distinct from any 
of the above named. The small, triangular leaves 
are greenish yellow, with a creamy edge when young, 
but ultimately have a broad silver margin. It is a 
beautiful Ivy with plenty of colour, but judging 
from the plant at Chiswick, it does not grow very 
fast. 
Madeirensis variegata. —The leaves of this 
variety are relatively large, rather elongated and 
deep green, with a broad but irregular silver margin 
and splashed with gray all over. It is one of the 
most distinct and beautiful of the silver-edged Ivies, 
but is rather tender, and requires the protection of 
a frame or cool greenhouse. It is largely grown in 
pots for market purposes. 
Flavescens. —The small three-angled leaves of 
this variety are at first greenish yellow or pale 
yellow, but finally irregularly clouded with a 
creamy hue. 
SucciNATA.— Here again the leaves are very small, 
and usually three, rarely five-angled, greenish 
yellow when young, ultimately splashed or marbled 
with a creamy marking, and having gray veins. It 
is a slow and weakly growing kind. 
Purpurea.— The leaves of this sort are usually 
three-angled, but are often broadly heart-shaped 
and undivided. When young they are bright green, 
but ultimately become very dark olive-green or of 
a purplish hue in winter. There is also a plant 
under the name of Atro-purpurea, which appears to 
be the same thing. 
Rugosa.— The three-angled leaves of this variety 
are bright green when young, but at length dark, 
dull green. The surface is slightly wrinkled or 
rugose ; hence the name. 
CoNGLOMERATA. —The leaves of this distinct 
variety are of two forms. At the base of the 
stronger growing shoots for the season the leaves 
are largest and the lateral angles or lobes infolded 
owing to the extreme crowding of the leaves due to 
shortness of the internodes. Towards the top the 
shoots are more inclined to elongate, and the leaves 
are smaller and flatter. They are dark green when 
young, but ultimately become olive green and 
heavily clouded with gray branching veins. There 
are two healthier and stronger growing plants under 
the name of Minima, but we fail to see any tangible 
and permanent difference by which to distinguish 
it. It is an excellent subject for rockwork as it grows 
upright for someyears, although the stems are liable to 
fall down after a time and then grow more rapidly. 
The same thing happens sooner when the variety is 
planted against a wall. The two forms of leaves 
then appear on the same plant, and evidently only 
denote different stages of the same individual. 
-- 
CLEMATIS MONTANA. 
Attention is so often called to the merits of this, 
certainly one of our most beautiful hardy climbers, 
that we feel somewhat diffident in again reverting to 
it, and would not do so but for the fact of having 
met with it trained after a different fashion to that 
generally in vogue. The plant in question has its main 
branches brought along on the top of a verandah, 
and the flowering shoots are allowed to hang down 
in front to a length of from three to four feet. 
As these hang loosely and close together the effect is 
simply grand, and it is certain that anyone who has 
not seen it trained in this fashion has never seen it 
to the best advantage.— W. B. G. 
A NEW SYSTEM OF 
HORTICULTURE. 
A NEW system of horticulture ! The mention of such 
a thing almost took one’s breath away, and caused 
one to wonder what was coming next. M'hat came 
next under our observation was an illustration of a 
glass structure on wheels, hot-water pipes, and 
boiler all complete, and the thought arose “ what a 
delightful toy for the amateur faddist ! ” A house 
that could be made to do the work of two or three 
such structures erected in the ordinary way, that 
will bring our crops on in regular rotation in spite of 
the east wind, the frosts and snows, the rains and 
sunshine of our very variable climate. What more 
could we want ? Something new in practical horti¬ 
culture ! Well, we begged leave to doubt it. It was 
an old idea trotted out in anew guise; a new' e*dition 
of Mr. Monro’s old project ; the tramway system in¬ 
troduced by the Rev. John Fountaine some twenty 
years ago turned round and given a fresh coat of 
paint ! A new idea I Why, it was as old as the 
Romans, for were not Cucumbers grown for the 
Emperor Tiberius, planted in boxes, grown in 
heated stoves glazed with talk or Muscovy glass 
(Lapis specularis), and wheeled in and out according 
as the weather was fine or otherwise 1 Something 
new, indeed. Well it seemed all these things rolled 
into one, and was no good, etc., etc. 
But new idea or not, a closer examination of the 
particulars, and an inspection of some houses built 
on the travelling system which are about to be 
introduced by the Horticultural Travelling Struc¬ 
tures Co., were sufficient to convince us of the fact 
that they were no mere toys, but of real practical 
utility, especially in relation to commercial horti¬ 
culture, and therefore specially worthy of the 
attention and consideration of all engaged in the 
cultivation of market products. 
The system is the invention of Mr. Pickering, a 
retired engineer and surveyor, who, being a keen 
amateur gardener himself, thought out the idea of a 
glass house on wheels for his own use only at first, 
but finding the results of his ingenuity so success.'^ul 
and practical, he has devoted the last three years to 
taking stock of the glass appliances of most of the 
leading market growers, ascertaining their require¬ 
ments, and working out his own scheme on 
scientifically accurate lines to insure a good 
practical type of structure, sufficiently strong and 
rigid to stand all ordinary wear and tear without the 
waste of an ounce of material, and that shall not 
cost more when complete than an ordinary 
house of the market grower’s type. This Mr. 
Pickering now claims to have accomplished, and on 
Monday a considerable number of press men were 
invited to a private view of several of the structures 
erected on the spacious floors of the Horticultural 
Travelling Greenhouse: end view.
