54 PRESENT-DAY GARDENING 



many town and suburban dwellings. These are heated by 

 a small boiler with hot-water pipes, a means, it should be 

 said, which is the only satisfactory method of heating 

 glass structures. To the species indicated for the smaller 

 and less safely heated structures may be added a very 

 wide range of subjects of great beauty. In such a structure 

 the Palms supplying decorative foliage may be much re- 

 stricted, or entirely dispensed with, as Cymbidium Lowi- 

 anum, C. giganteum, C. Tracyanum, and any others of 

 the section having evergreen leaves of much grace, are 

 decorative plants at all seasons, and possess the further 

 advantage of being furnished with fine spikes of flowers 

 for several months in the year. These large and strong- 

 growing species are specially adapted for the conservatory, 

 an Orchid house being unnecessary for them. 



To the heated conservatory also may now be handed 

 over the showier species and hybrids of the South American 

 Cypripediums (Selenipediums), which, probably because of 

 their very free-growing nature rendering them too large for 

 the Orchid house, and the ready manner in which they 

 may be increased, have caused them to be slighted lately 

 by growers of collections of Orchids. The air of the con- 

 servatory, rather drier than that of the Orchid house, suits 

 these plants admirably. Their bright evergreen foliage 

 and tall sprays of white and rose, or greenish flowers tinged 

 with purple, which often by succession keep the specimens 

 in bloom for six months in the year, render them beautiful 

 and interesting subjects for the conservatory. 



The strongest and best kinds to be acquired are 

 Selenipedium longifolium, S. Sedenii, S. cardinale, S. 

 calnrum, S. grande, S. Schroderce, arid S. albo-purpureum.
