rest. If during the winter months any of these plants begin to send out 
roots from the last-made bulbs, they may be repotted, but not disturbed 
more than is absolutely necessary. Owing to the large amount of water 
these Mexican Lzelias require whilst growing, exceptionally good drainage 
is necessary, and the compost for them is good coarse osmunda fibre. 
They should be potted quite firmly. The temperature of the Mexican 
house during winter should be about 55° by night, and the air of the house 
comparatively dry. Fresh air in quantity compatible with the weather 
should be afforded. L. rubescens, perhaps better known as L. acuminata 
or L. peduncularis, is a dwarf-growing plant, and is best cultivated in 
shallow pans, and suspended, when growing, in a sunny position in the 
warmest house, but now that the plants are at rest, the cooler atmosphere 
of the Mexican house is best for them. 
PERISTERIA ELATA.—This plant, when in bloom, is always of consider- 
able interest, on account of the central part of the flower being likened to a 
dove. It succeeds best in a stove temperature when growing, but now that 
the large pseudobulbs are fully made up, the drier and cooler atmosphere of 
the Cattleya or Mexican house is the best place for it. This species: 
requires a long rest, without which, however strong the pseudobulbs may 
be, flowering is problematical. The application of water to the plant while 
at rest needs care, and it is better to keep on the dry side than to afford too- 
much water. Mealy bug often affects this plant. 
BRASSAVOLAS.—B. grandiflora and B. venosa are now coming into 
flower, and are well worth growing, as their delicious perfume pervades the 
whole house, especially at night or early morning. Both grow thoroughly 
well when fastened to teak rafts, and suspended with their terete leaves im 
pendant position. Grow them alongside of Lzelia rubescens, and afford. 
them the same kind of treatment. 
OpontocLossuM crTRosMuM.—By this time plants of this lovely 
will have completed their growth, after which water should be gr 
withheld and in a few weeks quite discontinued. Owing to dryness at the 
root during the resting period, the pseudobulbs will probably shrivel a good 
deal, but this is not to be feared, unless carried to excess, it not being 
injurious to the plant, as when the flowering period again arrives they 
quickly return to their normal condition after being kept well watered for * 
few days. O. Reichenheimii and O. leve, having likewise finished ne 
growths, should receive but little water at the roots during winter. These 
three distinct Odontoglossums should be placed in the lightest and coolest 
part of the Mexican or Intermediate house during their season of rest. os 
TRICHOPILIAS.—T. fragrans, one of the very best of eae ee a 
Orchids, is now showing its flower spikes, and will soon be in bloom. 2
