THE GARDENING WORLD. 
January 31, 1903. 
consider it one of the prettiest of its class to be seen at this 
period of the year. See our illustration on p. 89. 
A closely-related plant, and not yet very old, is that named 
Zygopetalum leucocliilum, which has for its parentage Z. 
Mackayi x Burkei. The flowers are not remarkable for their 
showiness, but they are sweet scented, and attractive at this 
period of the year on account of the very distinct-looking 
white lip, which shows up in marked contrast to the other 
parts of the flower, which are light green, lined and spotted 
with brown. Our illustration of this on p. 91 will give readers 
an idea of the general character of the flower without further 
description. 
Another plant belonging to this same group was Z. Gautieri, 
having a purple-violet lip and green sepals and petals banded 
with brown. 
Dendrobiums were very numerous, and consisted chiefly of 
hybrids. A few species, however, are also in bloom or com¬ 
mencing their show. These would include D. aureum, D. 
wardianum, and I). crassinade ; of both of these latter there 
TMoschosma ripabium. 
are some splendid species in a specially-constructed house, where 
the plants hang from the roof, over a tank of water which will 
presently be occupied with Water Lilies and other aquatics. 
There is a fine variety of D. nobile, named D. n. murrhinianum, 
having white flowers and large deep purple blotches upon the 
lip. 
Yeiy handsome also is the peloric form of the same species— 
namely, D. n. Cooksonii, in which the petals imitate the lip to 
a certain extent. 
Amongst hybrids, very pretty and clean-looking are the pale 
f primrose shining flowers of D. Wiganiae, which has a maroon 
blotclr on the lip. Very distinct in its way is D. Cordelia, 
having a rose blotch on the lip, the rest being white. D. C. 
flavescens only differs by having a yellow lip streaked with 
deep brown. The maroon blotch on the lip of D. euosmum 
virginale shows up well against the white of the rest of the 
flower. Pretty also is D. splendidissimum leeanum, with rosy 
tips to the petals and sepals and a rich blotch on the lip. D. 
euosmum delicatum has white flowers and a purple blotch on 
the lip. 
Altogether distinct is D. Imogen, having pale yellow flowers 
produced in pairs on the stems. This yellow colour is derived 
from the pollen parent, D. signatum. Another handsome 
hybrid is that named D. Edithiae, having white sepals and 
petals, shaded with rose on the outer half. The lip has a 
large and showy blotch of purple on the disc. The name, D. 
wardiano-japonicum album, will give an idea of the general 
character of the flowers without description. 
One of the most useful Oncidiums at this period of the year 
is 0. varicosum, with its large yellow lip. It is, however, sur¬ 
passed by its variety, 0. v. Kogersii, which has very large dark 
flowers. 
Another species flowering out of season is 0. pulvinatum, 
bearing large panicles of yellow flowers, barred with brown. 
The usual flowering period of this plant is May and June. 
Several Epidendrums are already in bloom, if, indeed, they 
ever cease flowering at any period of the year. That in flower 
at present is E. Wallisio-ciliare, with yellow sepals and creamy 
white lip. Several of the species of Dendrochilum are just 
on the point of expanding their flowers, and will presently be 
very interesting on account of the Lily of the Valley habit of 
the plants and the sweet-scented character of many of the 
flowers. 
Messrs. Sutton and Sons, Reading. 
Hitherto the glass-houses of Messrs. Sutton & Sons, Reading, 
have been situated at the Portland Road Nurseries, but for 
some months past a splendid new range of glass has been in 
course of construction on the Trial Grounds, lying between the 
Great Western and the South-Western Railways. The range 
consists of twelve houses, eadr 60 ft. long, with a large central 
pavilion, and the whole connected together by means of a glass 
corridor along the northern side. Four of these houses are 12 ft. 
wide, the rest being 14 ft. wide. A few of them at either end 
of the range are smaller, being intended for a different purpose. 
All of them are span-roofed, the angle of elevation being about 
40 deg. 
Needless to say, eveiy one of these houses is intended to 
admit the maximum of light, and to suit exactly the kinds of 
plants to be cultivated in them. Past experience has enabled 
the firm to build this range all compact and exactly fitting their 
requirements. The pavilion in the centre at present looks like 
a winter garden, but it is intended to furnish many con¬ 
veniences, such as loading vans with flowers, and as a luncheon 
hall for large parties of visitors, as happened on the occasion 
of our visit. Behind the pavilion is a veiy large potting shed, 
which can also' be utilised for other purposes when required. 
Various other conveniences are located in the neighbourhood 
of the potting shed. 
The whole of the range is heated by four immense boilers, 
one of which is capable of heating half the range under all 
ordinary circumstances, its companion being only necessary in 
the case of accident or when the weather is unusually severe. 
Concerning the method of heating, the arrangements are 
admirably designed and wel 1 executed. The hot-water mains 
are 6 in. in diameter, and are taken through a tunnel, con¬ 
structed so that workmen can examine them at any time and 
execute any necessary repairs. The roof of this tunnel is 
sufficiently high for a workman to walk through it with lantern 
in hand and inspect the pipes at stated intervals. 
The stokeholes are large, with an admirable arrangement for 
storing the coke within a short distance of the furnaces. ‘The 
carter has only to fix a shoot to the end of his cart and tumble 
the coke into the place provided for it. In the roof over the 
stokehole is a large tank connected with the boiler by means 
of a pipe, so that warm water for any particular purpose may 
be obtained ready to hand whenever wanted, as, for instance.
