EPIPHYTAL EXTRA-TROPICAL ORCHIDEiE. 



343 



In regard to potting, it is necessary to pay every attention to have them 

 well drained, as they are more liable to suffer from an excess of damp 

 than the epiphytal species, and a soil of turfy, sandy peat, with a small 

 portion of mould of decayed tree leaves, is found to be best for them. 



In regard to temperature, the majority of them require the same as the 

 epiphytal ones : there are a few exceptions in regard to this in the 

 case of some Chinese species ; but these can be placed at the coldest end 

 of the house.

III. EPIPHYTAL, OR PARASITICAL, EXTRA-TROPICAL ORCHIDE^. 



The species which come under this head are as yet few in number, and 

 those which we have selected will flourish in a well-regulated green- 

 house, and hence be within the means of those who do not possess a 

 stove, and are, at the same time, curious in having a few of these extra- 

 ordinary plants in their collection.
