Stove orchids, not possessing much beauty, but are 

 interesting, curious little plants. They thrive best upon 

 blocks of wood, with a small portion of moss tied to the 

 block. The best form of block is a round one, with 

 the top cut sloping at an angle of 45, the plant to be 

 fixed on the sloping part. These blocks can then be 

 placed on the lower end, which should be cut horizontally, 

 to allow them to stand firmly in that position. They 

 are also grown in small pots and pans.
