that they make no mistakes regarding so very important a 

 subject. 



With regard to the genus Zygopetalum itself, it is distinctly 

 separated from Odontoglossum by the crest of its lip being 

 solid and transverse, by its column having no ears, and by its 

 sepals and petals being directed upwards above the level of 

 the centre of the flower. 



Those who cultivate the thin leaved species of Oncidium, 

 such as O. altissimum, will find the same treatment appli- 

 cable to this plant. It will grow very well in a pot, but better 

 if hung up ; if treated in the former way it should be planted 

 upon the top of the soil, and its roots allowed to scramble 

 over the surface of the pot. In either case its roots and 

 leaves must be well watered and syringed during the growing 

 season, and must never at any time be kept so dry as Cata- 

 setums and plants of that description.
