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 tothis 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.
