ORCHIDACEOUS HOUSE.

stalks of other plants that arc hollow, are 
laid anions the pots and plants for this 
purpose. Potatoes or turnips are cut in half, 
and the halves hollowed out, andlaid with the 
hollow side downwards among the plants, 
(leaving room for the insects to crawl under) 
and they will collect in these both for shelter, 
and also for the purpose of feeding. What- 
ever form of trap is employed, it should be 
examined every morning, and the insects which 
are collected should be destroyed. 
Plants going out of flower. — Where the 
plants, when in bloom, have been removed to 
the sitting-room, and retained there some time, 
they will doubtless have become rather dry, 
as it i* not advisable to give them much water 
in such a situation. If they are of the class that 
are going to rest, remove them to the dry- 
house ; but if they have to make a growth, 
have them carefully and regularly supplied 
with water (always used in a tepid state) and 
placed in the growing-house. 
Moisture. — It has been already stated that 
the atmosphere of the house should be sup- 
plied with as much moisture as it will take up 
from a continually moistened floor, &c. Few 
of the plants, at this season, will require water 
directly applied, except in those cases alluded 
to above. It will be necessary to see that 
water does not get collected and lodged at the 
base of the leaves ; this would render them 
liable to die away. 
Cyrtopodium. — The plants that have been 
resting through the winter, may now be taken 
out of the pots, the old soil removed, the bulbs 
cleared of the remains of the former foliage, 
potted in rich turfy loam, and plunged in a 
mild bottom heat. When they commence 
growing, let it be encouraged by every possi- 
ble means. 
Phaius grandifoliui should be treated in 
a similar way. It is an evergreen terrestrial 
plant, and therefore requires watering, more 
or less, all the year. It is an exceedingly 
beautiful and highly useful plant for removing 
to the sitting-room. Any of the plants that 
are now growing freely, and coming into 
flower, should get a regular but moderate 
supply of moisture. Several of the Bletias 
and Calanthcs require very similar treatment. 
Dendrobium. — The plants that have been 
kept dry, and are now showing flower, should 
receive a moderate supply of water, and should 
be placed in a favourable position as regards 
heat and light. I), nobile, D. ccerulescens, 
D. speciosum, D. moniliforme, D. aureum, 
and D. Pierardi, and its varieties, will probably 
be in bloom. The same treatment may be 
given toother plants showing blooming stems. 
Onridium. — Many of these will be flower- 
ing about Ibis time, such as O. ornithoryn- 
chum, O. leucochilum, 0. Cavendishianum, 
and 0. Suttoni; they should get a fair supply 
of moisture. 
Ccelogyne. — Of these, such as Gardneriana, 
maculata, Wallicbiana, &c, will be showing 
flower, and should be potted as soon as the 
flowers are gone past ; keep the plants grow- 
ing, and other flowers will be produced about 
August, and then after they have perfected 
their growth, they must be kept cool and dry 
till the following January. 
Plants coming into flower. — Besides those 
mentioned under various other heads, as 
Phaius, Dendrobium, Oncidiums, and Cce- 
logynes,the following showy kinds,of which the 
plants may have been rested early in autumn, 
will probably be in bloom. La:lia albida, 
L. anceps, L. autumnalis, L. grandiflorus ; 
Zygopetalum Mackaianum, Z. crinitum ; Epi- 
dendrum nutans ; Brassia maculata, B. caudata 
Stanhopea Wardii ; Cyrtochilum maculatum ; 
Peristeria guttata ; Aspasia epidendroides ; 
Trichopilia tortilis ; Brassavola venosa, B. 
Martiana ; Cypripedium barbatum, C. venus- 
tum, C insigne. 
To secure growth only. — If the object is to 
cause a greater degree of development than 
ordinary, rather than to induce bloom, which 
may sometimes be the case with young or 
small plants, which it is desired to grow into 
specimen plants as quickly as possible, the' 
plants must be submitted to a greater degree 
of heat, and also of humidity, and the resting 
period must be limited, in this way two 
growths instead of one, and sometimes even 
three or four may be obtained. Mr. Paxton 
records the following facts which bear on this 
point : — On the 20th of May, 1837, 1 received 
a very small damaged plant of a new Stanho- 
pea ; I allowed it to get perfectly dry ; it was 
then potted and placed in a strong bottom 
heat, with a strong heat above ; the plant 
began to grow in about a fortnight, and at 
the end of July had perfected a small bulb : 
the plant was then kept dry for about a fort- 
night, and was again placed in a strong bottom 
heat, and in a temperature never lower than 
70 degrees, but often amounting in the day 
to from 90 to 100 degrees. By the end of 
September it had perfected a second bull). 
considerably larger than the first. The plant 
was again dried on a hot flue for a fortnight, 
and then removed into a larger pot, and eleva- 
ted a little above the surface ; it was again 
replunged in a Strong bottom heal, and by the 
end of December had perfected two more 
bulbs, making four since the commencement. 
I should here observe that the plant had 
only one bulb when I received it. The plant 
was now dried for a month, then repotted and 
placed as before, in a strong heal : about the 
first week in April, (he plant bad made two 
more perfect bulbs, the process of drying was
