﻿THE ORCHID REVIEW. [February, 1904. 



satisfactory. Their culture is, on the whole, easy, if treated in accordance 

 with their very simple requirements. There must not be too much 

 coddling ; nor should they be starved for the want of water, or other 

 necessaries, such as repotting, &c, when required. Occasionally we get 

 examples where the new growth, or rather the last made pseudobulb, 

 overhangs the side of the pot, and the new roots are consequently growing 

 out into space, where they often sooner or later come to grief. The ordeal 

 of flowering to such plants is most exhaustive, and they will sooner or later 

 collapse. Unless Laelias have overgrown their receptacles, once in about 

 three years is often enough to furnish new materials throughout, all else 

 that is required being an occasional top dressing. Should any of the 

 plants require attention, either in the way of repotting or top-dressing, it 

 should be proceeded with dining this month or next. All the Mexican 

 Ladias require but little water during the winter to keep them plump, but, 

 like Cattleyas, they should have enough to do this without signs of unduly 

 shrivelling. They require plenty of sunlight, with an abundance of air, 

 which will all tend to keep them robust. 



Cattleya Triana; and its varieties will be at their best during this 

 month. It forms a most beautiful and useful species, and is one of the 

 free.,t of Cattleyas to grow and flower. It soon commences to root and 

 grow after flowering, when repotting or top-dressing should be attended to. 

 C. Percivaliana, although the flower is very rich and beautiful, cannot be 

 compared to the first-named for usefulness. Sometimes this species fails 

 to produce its flowers satisfactorily, even after making good robust 

 pseudobulbs, with plenty of sheaths. By keeping the plants rather dry and 

 warm, however, the failure is not so great ; yet there are some which fail to 

 come, and this circumstance makes it appear to the more susceptible to 

 atmospheric conditions than is Triame. 



There are a number of Oncidiums which prefer the Cool House culture, 



of these is O. serratum, which has just gone out of flower, and is 

 commencing to make fresh growth. In habit it is similar to O. 



coolest part of the house. When grown in pots in leaf soil, surfaced over 

 with fresh chopped sphagnum moss, they soon become fine specimens. 

 The treatment is the same as for other cool Orchids. Water with care 

 during the winter, letting the material appear dry for several days before 

 giving water ; at the same time taking care not to get the atmosphere too 

 moist, by damping down too often. If the plants have been awakened, it 

 may sometimes be advisable not to damp the floors for a day or two 

 afterwards, until they get somewhat dry again. In anv case once a day 

 will be found often enough for this operation. Oncidiums delight in
