turned out, without the least root disturbance, and repotted into larger- 
sized pots. Such varieties as rubella, Leopoldii, and superba will not be so 
forward in growth as the others, but they will need similar treatment. 
During the winter and early spring months the leaves of these Miltonias are 
very liable to become spotted at the tips, which, if the growths are weak 
and unsubstantial, indicates that too much heat and moisture are afforded. 
These plants should at all times have plenty of fresh air, and being now in 
full growth a light syringing on bright, sunny mornings from a fine sprayer, 
well up under the foliage, will greatly encourage growth, and assist in 
warding off insect pests. The now rare M. Phalznopsis will be passing 
through its flowering season, and after the flowers are over still keep the 
plant moderately moist at the root. 
L&LIA MONOPHYLLA.—A little gem among Lelias is the bright scarlet 
L. monophylla, a plant that has always been considered difficult to 
import and establish, but when it once becomes well rooted, and not 
allowed to over-flower itself, will keep in good health for a long time. If 
the plants require fresh material now is the best time to afford the same. 
Place them in small, well-drained pots, in a mixture of Osmunda and Ar 
fibre. Cut the fibres up finely and pot each plant with moderate firmness, 
in such a way that when the plants are watered water will pass as freely as 
through a sieve. A good plan is to elevate these small plants among those 
of Miltonia vexillaria, the plants thus obtaining the same cultural conditions 
as advised for these species. 
VANDA TRICOLOR.—Plants of V. tricolor and V. suavis will now be 
growing freely, and should receive a little extra water at the roots, their 
flower spikes being just discernible. Every precaution should be taken 
that the plants are not placed in a position whereby they will receive drip 
from the roof, which is likely to accumulate at the base of the leaves and 
cause the spikes to decay. These tall growing plants require to be carefully 
Protected from strong sunshine at all times, especially those that were 
repotted at the beginning of winter, as they are liable to lose a number of 
their lower leaves if exposed for any length of time to the direct rays of the 
sun, particularly during the early spring months. 
TEMPERATURES.—Maintain the following temperatures : Cool house, 
50° to 60°; Cattleya and Intermediate houses, 60° to 70°; East Indian 
house, 65° to 75°. The lowest temperatures are for night and ene highest 
for noon. The Mexican house should be about 55° at night, rising in the 
day by sun-heat to 80° with plenty of air. The Cool houses must have 
Plenty: of air at all times, and the next two divisions a moderate supply 
both by night and day. Give a little air to the East Indian house wie 
€ver possible. If on mild nights the lower ventilators are left partially 
pen no harm will accrue.
