THE MOST USEFUL ORCHIDS 



ADA 



An Orchid that ought to be more popular than it is with amateurs 

 who have quite limited conveniences for the cultivation of those 

 kinds that succeed under cool treatment is Ada aurantiaca. 

 This species comes from a considerable altitude in the Colombian 

 Andees and may be grown with Odontoglossum crispum. It is a 

 showy Orchid, and during winter or spring it gives arching spikes 

 of brilliant orange-coloured flowers. For its colour alone it 

 thoroughly deserves a place in every collection of cool Orchids. 

 If Ada aurantiaca opened its flowers a little wider than it does, 

 and carried its spikes on rather longer stems, its popularity would be 

 very great. Perhaps in the near future our hybridists will evolve 

 an Orchid with the improvements suggested, and without any loss 

 of the many good points this plant possesses. Given the same 

 conditions in every way as the cool Odontoglossums there is no 

 difficulty whatever in the management of this useful, interesting, 

 and handsome species. 



AERIDES 



These East Indian Orchids have for many years been out of 

 fashion, and it is hardly likely they will be ever grown so largely 

 as in the earlier years of Orchid culture. By far the larger 

 number of species need to be grown in a very warm house, but 

 there are a few which come from a higher elevation than the
