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 he 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 in summer. A night temperature of 60° in winter and 
70° in summer will be amply sufficient for its growth.
