366 THE ORCHID REVIEW. [DECEMBER, 1915. 
white Orchids suitable for any kind of decoration are not common. This 
plant requires but a trifle more heat than Odontoglossum crispum, so that 
it may be grown at the warmest end of the Cool house, or in any moist 
house where the winter temperature does not fall below 50°. Plants of T. 
rostrata, a rather long, slender-bulbed species, which throws many 
moderate-sized white flowers in the spring months, will also thrive under 
the same treatment. T. suavis, T. coccinea, tortilis, crispa, marginata, 
lepida, Backhouseana, Wageneri, Galeottiana, and T. laxa all require a few 
degrees more heat. Most of these plants will have made up their growth, 
and must not. be so often watered, or their pseudobulbs and leaves will 
quickly become spotted. So long as the bulbs remain plump, very little or 
no water will be required, but if they show signs of shrivelling, a moderate 
amount of moisture may be afforded. During their resting period 
Trichopilias should be placed in a cool dry part of the Intermediate house. 
They are fond of a light position, but not actual sunshine, as the sun will 
quickly turn the leaves from the deepest green to an unhealthy hue. When 
showing their flowers remove the plants to a shady position in the Cattleya 
house, as they will open better there, and be less likely to become spotted 
than if left in the cooler division. Trichopilias should be repotted soon 
after growth commences. Well-drained osmunda fibre is in every way 
suitable for the roots to run in, and as these from healthy specimens are 
large and many in number, they will take considerable pot room. In 
potting, keep the plants well elevated up in the pots, so that they can be 
easily watered without any fear of moisture lodging in or about the young 
growths, as these are easily rotted. Those plants now flowering will be 
best potted early in the spring. When growing freely they will take as 
much water as any Cool-house Orchid. In cases where from any cause the 
breaks of the plants started late, and are in consequence now growing, 
give them a light position in the Cattleya house. Some of the smaller 
kinds may be suspended from the roof on the shady side of the house. 
MiLTon1as.—Plants of M. vexillaria are growing rapidly at this season, 
and the roots in full activity, therefore enough water should be afforded to 
keep the sphagnum on the surface in a fresh growing state. These growing 
plants will need constant attention, as the young leaves frequently stick to 
each other so firmly that they soon become crumpled if not watched and 
carefully separated ; and it will be noticed at frequent intervals that at the 
base of some of the young growths there is a brown, damp-looking outer- 
sheath which clasps the growth so tightly that the young roots come up 
nside the sheath into the air, and make no further progress, instead of 
going down into the compost. This brown covering should be carefully 
slit in several places, and pulled off in small pieces. At this season the 
eaves of M. vexillaria are prone to damp off at the tips. When this
