two seasons to re-establish such plants and fit them for flowering. C. 
ocellata is an elegant little member of the genus that flowers in winter, it is 
-easily cultivated, and when fairly well established never fails to bloom. The 
rooting material of these plants should never be allowed to get dry until 
after the flowering season, when less moisture should be given ; they should 
•be grown in a cool intermediate temperature. C. barbata is another pretty 
and distinct winter-flowering species that succeeds well in a similar tempera- 
ure. During its period of active growth the plant enjoys a fair supply of 
water at the roots, but much less after its pseudo-bulbs are matured. The 
flowers will continue in perfection for a long period, provided they are kept 
free from damping. 
Preparing for Winter— During the dull days of winter all the light 
possible is needed by the plants, hence no time should be lost before 
cleansing the houses arid putting everything in order. It is a great 
advantage if each house, as it is taken in hand, can be cleared of its 
occupants, to permit of the ventilators being thrown wide open for a few 
hours after the work is done to sweeten the atmosphere before re-housing 
“the plants. Cleanliness forms an important feature in the successful culti- 
■vation of all plants, but none more so than Orchids. By keeping everything 
clean about the plants, and giving reasonable and proper ventilation, the 
plants will grow cleaner and be freer from insect pests. It is advisable to 
prepare for winter by reducing the temperature in all the houses a few 
degrees by night> and also by day in the absence of sun-heat. Much less 
moisture is now required, especially in the cooler divisions, where evapora¬ 
tion is slow. Henceforward all Orchids need all the sun-heat and light 
available, and, so long as the sun is capable of raising the degree of warmth 
•in the houses considerably during the middle hours of the day, full 
.advantage should be taken by the cultivator to admit fresh air, but fog and 
frosty air must always be excluded. A careful watch should be kept on the 
■outside conditions, for as the wind changes, so will the temperature of the 
houses be effected. 
Cattleya Warscewiczii rochellensis.— This beautiful albino variety 
appeared in 1888, in the establishment of Messrs. Siebrecht and Wadley, of 
New York, whence it passed into the collection of F. L. Ames, Esq. It is 
figured in Reichenbachia, ser. I., ii, t. 85. On July 21st, 1921, a First-class 
'Certificate was awarded to Cattleya gigas rochellensis at the Manchester 
Orchid Society, and although the name gigas is generally used in gardens 
on account of its descriptive nature, it is, in fact, a later name than the 
somewhat awkward Warscewiczii. The plant shown at Manchester by Dr. 
F. Bedford had pure-white sepals and petals, a light rose tint on the lip, 
.and yellow in the throat.
