tion of flowers of sulphur, in order that the fumes may 
be dissipated without burning the sulphur, as that would 
destroy the plants as well as the spider. If the pipes, or 
the plate, are nearly as hot as water can make them 
when almost boiling, the fumes will kill the insects with¬ 
out injuring the plants ; but for many tender plants the 
water must not be warmer than from 180° to 200°, un¬ 
less care is taken to give a very little air. When done 
flowering, the plants should be pruned and syringed, 
and, if possible, kept close and moist until fresh growtli 
has commenced. Then expose the plants to the full air 
by degrees, and give them a shady place out of doors 
during the hottest months, laying them down on their 
sides and syringing them several times with soap water, 
and using clean water in a similar manner the following 
day. By the middle of September the plants should 
stand lull in the sun, protected, however, with glass, or 
any other means, from drenching rains. They should 
be housed by the end of October, and plenty of water 
given to them at all times, especially when growing and 
flowering. 
Coronilla glauca.— The keel of the flower of this is 
so acute, as to resemble the turned-up point of a Chinese 
mandarin's slipper. This yellow-flowered plant is well 
known; a native of France, and has been grown here 
more than a hundred years. Flowers sweet-scented in 
the daytime. It is a compact dwarf bush. The C. 
variegata I noticed the other week. 
C. valentina, or stipularis, is more open in its 
growth than glauca; it is a native of the south of Italy, 
and its yellow flowers are scented at night. It is almost 
always in bloom, but February may be said to be the 
chief time for both. Treatment the same as for Genista 
and Cytisus ; they are not quite so much troubled with 
red spider, but a white scale frequently annoys them. 
For the latter, I have found nothing better than a solu¬ 
tion of clay or mud in water, made in a tub, the plant 
turned topsy-turvy in it, until every leaf was completely 
covered, then laying it down in a shed for a couple of 
days, until the mud was thoroughly dried, wheu rustling 
the shoots between the hands would bring off the most 
of the caked mud, and the vermin along with it. After 
several syringings and washings it might then be 
restored to its proper place. 
Where there is room all these plants make fine speci¬ 
mens when planted out, and would do very well in such 
orchard houses as Mr. Rivers’s, with the assistance of a 
brick Arnot’s stove. My space being occupied, I will 
merely mention a few more plants belonging to this 
group, and of dwarf compact habit, but requiring more 
care and chiefly peat soil to grow them in. 
Gompholobiinn grandiflorum and latifolium, blooming 
from February to August; Podolobium trilobatum, from 
March to June; Gastrolobium bilobum, from February 
to May; Goodia latifolia , from March to July; Pultencca, 
many species, from the end of February to midsummer; 
Scottia angustifolia, from February to June; Oxylobium 
cordifolium, March to June; Eutaxia myrtifolia, Bax¬ 
ter), and pungens, from March to July, and even later. 
All these, especially those ending hi lobium, will 
require treatment more like that spoken of for Chorozema 
than for Cytisus. R. Fish.

Cymbtdium aloifolium (Aloe-leaved C.); E. Indies.— 
This is a very old and handsome species. We know a 
garden in Wiltshire where there are several plants of 
it that are at least 10 years old, growing in 8-incli 
I pots, and although they have not been repotted the 
whole of that time, yet they grow and flower well. 
They are placed on a shelf against the back wall of a 
pine stove, and have made such a quantity of roots, that 
the plants are almost pushed out of the pots. To wet 
this mass of roots was quite out of the question. All 
that could be done was to syringe the whole plants fre¬ 
quently during the summer, and to keep them dry 
throughout the winter. Notwithstanding this almost : 
utter neglect, the plants, as we said before, grow well, j 
and sent down every summer numerous spikes of their 
beautiful flowers. And yet this species is said to bo 
terrestrial; that is, growing on the ground. What then, 
any one may justly observe, is the use of all your direc¬ 
tions about composts, pottings, moisture, growing and 
resting seasons, &c., &c. ? We can only use, in our de¬ 
fence, the old adage, that there is no rule without ex¬ 
ceptions. The plants referred to were in a moist pinery, 
and the moisture arising from the tan-bed, together with 
the steamings and syringings, was sufficient for the 
support of such old-established plants: besides, the 
leaves of this species are thick and fleshy, like its 
namesake the aloe, and in consequence can bear great 
extremes of heat and cold, drought and moisture, and 
from this extreme case we may learn the advantage of 
severely resting orchids of similar character. The flower- 
stems arise from the base of the leaves, and soon push 
forth and hang down gracefully over the edges of the 
pots. We have known one large plant produce as many 
as twenty of these handsome spikes averaging two feet 
each in length. The flowers are of a rich pale purple, 
striped down the centre with a long stripe almost black.

C. bioolor (Two-coloured 0.); Ceylon.—This grows 
on trees in its native wilds, but thrives well in a pot. 
The flowers are much like the first species, but a distin¬ 
guishing specific difference is tire presence of a sack or 
hag at the bottom of the lip, and also a number of 
stains and stripes of very deep crimson. Rare. ills. (id. 
C. Devonianum (The Duke of Devonshire’s) ; 
Khoozeea Hills.—Sepals and petals creamy white striped 
with red ; lip rich purple crimson. Flower-stems droop¬ 
ing. This fine species was found by Mr. Gibson, the 
Duke’s collector, growing on the trunks of decayed trees 
in hollows that wero filled with vegetable earth. Yet 
very rare. 105s. 
C. eburneltm (Ivory C.); East Indies.—Sepals and 
petals pure white and fleshy like ivory; the lip is the 
same colour with a dash of yellow in the centre. The 
flowers are very large and handsome, lasting a long time 
in flower. Flower-stems erect. This is the handsomest 
species of the whole genus, but it is very scarce. 210s. 
C. giganteum (The Great C.); Nepal.—The flowers 
are brown and purple. This is a noble plant with large 
short pseudo-bulbs, and very long leaves. The flowers 
are produced on long racemes, drooping, and very hand¬ 
some. 42s. 
C. pendulum (Pendulous C.); Sylhet.—Sepals and 
petals brown; the lip is red, striped with white. A 
noble handsome species. 42s. 
C. sinense (Chinese C.); China.— Sepals and petals 
brown and purple, the lip is yellowish green, spotted 
with purple. The flowers are produced, very numerously, ; 
on tall erect spikes, and are deliciously fragrant. On that 
account the plants are worth growing. 
There are several more species, but we consider that 
we have enumerated the best. It is a handsome genus I 
of plants easily grown. 
Culture. —Though several of the species are found on : 
trees, yet from the peculiar situations in which they 
grow, namely, in hollows of the trees and in the joints 
where the branches meet, in which situations there are 
deposits of decayed leaves, sticks, and other matters of 
nourishing qualities to the plants, it is found in culti- ,
