now growing vigorously, therefore will require more water at the roots. 
As a preventative against red spider, which sometimes infests them, a slight 
spraying under:their leaves from time to time will be beneficial, but water 
must not be allowed to enter the centre of the new growths. P. humilis 
and others which have just passed out of bloom, and are now starting to 
make new growth, may have attention as regards repotting, following the 
same procedure as previously advised. 
PHAL#NopsIs.—These are not grown so numerously as once they were, © 
and by many they are considered refractory subjects; but, still, there are 
few plants which can compare with them for beauty. They are best grown 
in baskets suspended from the roof, and not placed too near the glass, as 
they are liable to suffer from extremes of heat and cold. Plants that are 
commencing to make new roots may have any attention that is necessary 
as regards the supply of new rooting material. These plants, like many © 
other difficult subjects, are often allowed to suffer for the want of new 
material, as many are afraid to disturb them owing to their character. | 
Healthy established plants that have roots clinging to the baskets in which 
they are growing should not be disturbed, beyond removing the old decayed 
rooting material, and this must be done with care. Those in need of fresh 
receptacles should have any clinging roots carefully detached with the aid 
of a thin-bladed knife or similar article. Select for each plant a suitable | | 
basket, or suitably drained pan, then work the compost carefully amongst 
the roots, finishing with the crown of the plant slightly higher than the 
edge of the basket, or the rim of the pan. A clean fibrous compost with | 
live sphagnum moss is a suitable rooting medium. These plants are best 
accommodated in a house to themselves, where a hot humid atmosphere 
can be maintained whilst they are making their growth, with a slightly 
lower temperature and drier atmosphere whilst at rest. Having no pseudo- 
bulbs, every care is necessary at all seasons to prevent any harm overtaking — 
them. 
L#LIA MONOPHYLLA.—This bright scarlet Lelia is not grown as much 
as its merits deserve. It is not difficult to cultivate, and should be grow! in 
small well-drained pans, potted firmly in a clean compost made up of AI 
fibre and sphagnum moss. It succeeds under precisely the same conditions | 
as Miltonia vexillaria but, owing to its stature, when grown with that 
species, must be elevated well up to the light. : 
MILTONIA VEXILLARIA, and its hybrids, are pushing flower spikes from 
the partly-developed pseudobulbs. While in this condition the plan's 
should be watered whenever they become dry, and towards the end of the 
month may be placed in cooler quarters. The warm end of the Cool house 
or the coolest end of the Intermediate house, will answer their requirements 
At this season every precaution must be taken against the attacks of thie
