This genus delights to grow in a composition 

 composed of chopped sphagnum^ tufty peat, and 

 potsherds. Give good drainage, and elevate the 

 plant above the rim of the pot : those of the 

 weakest kind succeed best upon wood. For the 

 pendent racema varieties use shallow pots or bas- 

 kets. A moist stove suits them best when growing, 

 and a cool house when dormant. Previous to vege- 

 tation, they may be repotted without injuring the 

 roots.
