THE ORCHID GENERA 



plenty of water at all times. It is a dwarf-growing 

 plant, but, if suspended to the roof glass, the leaves often 

 assume a sickly yellowish hue, and it gradually becomes 

 unhealthy. 



Pachystoma 



P. Thomsoniana is a native of West Africa at a moderate 

 elevation, which indicates a constantly warm moist atmo- 

 sphere, such as is maintained in the East Indian house. 

 It thrives best in a shallow pan, leaf soil being used for 

 it to root in. This Pachystoma is a very lovely species 

 and is always highly appreciated when seen in perfection. 



Paphinia 



A small genus of very remarkable epiphytal Orchids, 

 all South American. The species — P. cristata, P. 

 grandrflora and P. rugosa, have short clustering pseudo 

 bulbs, bearing two or three leaves. The short scapes 

 are pendant, having generally two flowers. The plants 

 are best cultivated in small shallow pans, with leaf mould 

 for the roots to run into. Although small growing, they 

 should be stood low down upon the stage on the shady 

 side of the East Indian house. As the Paphinias 

 naturally grow in a very humid atmosphere, their 

 immediate surroundings must always be moist, but 

 when not growing water should be given carefully and 

 sparingly. 



Peristeria 



All the known species contained in this genus are of 

 horticultural value. They are natives of Central America. 

 The type species P. elata was first known in 1826, and 

 flowered in this country in 1 83 1. It is a strong growing 

 handsome species, the flowers being waxy white with
