﻿THE ORCHID REVIEW.

grown in a cool house, and its large yellow cup-shaped flowers are very- 

 handsome. It is a terrestrial species, and likes a rather heavier compost 

 than the epiphytic ones previously mentioned, so that the addition of a little 

 fibrous yellow loam to the compost is beneficial. It should be repotted 

 early in March, as soon as the flower buds begin to push, and when growth 

 is active it likes a good supply of water, but after the pseudobulb is com- 

 pleted, a good rest, with the soil kept just moist only. It should be placed 

 in as warm a position as possible during the winter. The other species of 

 Anguloa require identical treatment. 



Ccelogyne cristata is a handsome species which should be in every 

 collection, as it is very easily grown, and produces a profusion of its beauti- 

 ful white flowers in the spring. In the typical form the disc of the lip is 

 deep yellow, and pale yellow in the variety Lemoniana, while in the variety 

 alba the whole flower is of the purest white. It does best in pans or 

 shallow pots, in a mixture of fibrous peat and sphagnum moss, with ample 

 drainage, as it likes plenty of water during the growing season. When at 

 rest during the winter the compost should be kept just moist, and until the 

 flower-spikes appear, when the supply should be gradually increased. If 

 the compost is in good condition the addition of a little fresh material 

 among the roots will often serve instead of repotting, as it should not be 

 pulled about more than necessary, and a little very weak liquid manure 

 applied occasionally during the growing season is beneficial. 



Old-World species suitable for the Cool house are not numerous, as the 

 majority of them like a rather warmer temperature during the winter than 

 is beneficial to the Odontoglossums and their allies, but if the house contains 

 a partition, and the piping is arranged so that one end can be kept a few 

 degrees warmer than the other, many more species can be grown success- 

 fully. If the house runs north and south the warmer division should be at 

 the south end, so as to get the warming influence of the sun's rays as much 

 as possible. During the summer no fire-heat will be required in either 

 division, excepting a spell of cold weather intervenes, and the temperatures 

 will be regulated by means of the shading, ventilation, and damping down r 

 the chief difficulty during hot weather being to keep the cool division cool 

 enough. The arrangement mentioned will greatly assist the grower in pro- 

 viding that slightly warmer position which a few otherwise cool Orchids- 

 seem to require for their perfect development. A few of these may now be 



Vanda Kimballiana is a charming Burmese species, with terete leaves 

 and racemes of white and purple flowers, which are produced during the 

 autumn. It succeeds in a hanging basket, in a compost consisting of 

 sphagnum moss with a little fibrous peat, which should be kept just moist 

 during the winter. Dendrobium Jamesianum also succeeds in hanging.
