 over all the species of the genus. One of the grandest sights ever 

 witnessed was that in the collection of Baron Schroeder, where 

 upwards of 500 spikes of flowers were to be seen some time 

 ago. To grow this section satisfactorily it is advisable to afford 

 strong light and a hot, humid atmosphere during the growing 

 season, with a cooler and drier atmosphere during the period of
