BOTANICAL TERMS. 
kept in a state of perfect rest for some time to 
come. 
Afanettias, and other tender climbers, should 
be kept in a cool, dry and airy place, and re- 
ceive only sufficient water to keep them from 
dying down. 
Melastomas. — See last month's directions, 
which may in this case be followed. 
Melo- Cacti must still be kept dry and in a 
free circulation of warm air; water only to 
prevent shrivelling. 
JMusas. — Guard against damp in the heart 
of the plant, and also against spots on the 
leaves, by keeping up a dry atmosphere. 
Nepenthes (Pitcher-plant). — Still maintain 
a warm and comparatively dry atmosphere 
about the plant. 
Neriwns. — Introduce more to the forcing 
house, and remove such as are forward enough 
to the conservatory. They require a liberal 
supply of water when growing. 
Nymphoeas (Water lilies).— Still keep the 
roots rather dry, and in a rather low tempera- 
ture. 
Palms. — Keep as previously directed. 
Thunbergias. — The perennial sorts should 
still be at rest, as any growth made now 
would only weaken the plants. 
Vincas. — A few may be placed in a warm 
house and their shoots be allowed to grow ; 
they will soon be in full flower. 
THE ORCHID HOUSE. 
Temperature. — The warm house for the 
Indian species 65 to 70 degrees by day, 55 to 
60 degrees at night; the cool, or Mexican 
house, 60 degrees by day, and 50 degrees at 
night. Rather lower than this in clear frosty 
weather. 
Ventilation. — Very little air can be ad- 
mitted to either of the houses now, and when 
air is given the ventilators ought to be covered 
with canvass, close wove wire, or similar ma- 
terial ; and they ought to be so placed that the 
cold air must pass over the pipes or othef 
heating apparatus. 
Watering. — Very little water will be re- 
quired about the plants ; steaming the houses 
in the morning when the weather is fair will 
be as much as will be necessary in that way. 
Plants in a growing state should be occa- 
sionally watered with great care, and always 
soon enough in the day to allow them to dry 
externally before the evening. 
Insects. — The same unremitting search 
after and destruction of all sorts of injurious 
vermin must be kept up. 
Potting. — Attend to this before any of the 
plants advance too far in their growth, as it 
can hardly be done at such a time without 
material damage to the roots. 
Soils. — Keep a sufficient stock in -doors in 
the dry to meet the demand ; never using any 
until it has acquired the temperature of the 
house in which it is to remain. 
Imported Plants should be treated as ad- 
vised last month. 
A'erides, Saccolabium, and Vanda. — Keep 
these in a state of rest, applying water very 
cautiously. 
Cymbidiums. — If rested for a time the 
slightest increase of heat and moisture is gene- 
rally sufficient to excite these plants to pro- 
duce their flowers, when they should receive 
an additional supply of water. 
Cattleyas. — Maintain these in a cool airy 
temperature, applying very little water until 
the flower spikes appear, when the heat and 
moisture must be increased. 
Dendrobiums.—Keep these in a state of 
rest, as before recommended. 
Oncidiums. — Continue these in a state of 
rest, being careful that no drip or other 
moisture lodges among the leaves. 
Stanhopeas. — A cool rest should be conti- 
nued to these until the season advances or 
until they show bloom, when the heat and 
moisture should be increased about them.
