found beneficial, als» damping among the pots with soot water. After 
flowering is over, they are kept fairly moist for a few weeks, which enables 
them to make fine bulbs, after which the supply is reduced, but they are 
never allowed to become dry enough for the bulbs to shrivel. Under this 
treatment the plants do not deteriorate in vigour, and nine perfect flowers 
have been produced on a spike. Another photograph shows a plant lis 
10} inch pan, bearing fifty-five fine flowers. The species is a native of 
Guatemala, and was introduced by G. Ure Skinner about eighty years ago.
