which it indicates the unusual form of the narrow incurved 

 wings of the column, and a thickening of the margin of the 

 lip near its base. 



It is a stove plant, and requires to be grown in a mixture 

 of turfy peat and potsherds ; so that the whole may be effi- 

 ciently drained. A smaller pot, inverted in the one in which 

 it is potted, allows the warmth to rise through the soil, and 

 makes the whole lighter than when it is drained at the bottom 

 with potsherds. It may also be grown suspended from the 

 rafters of the house like other air plants, provided it is kept 

 moist enough during the growing season. Like all these 

 plants it requires a humid atmosphere, a liberal supply of 

 water when growing, and partial shade during bright sun- 

 shine m summer. A night temperature of 60° in winter and 

 70* in summer will be amply sufficient for its growth.
