This fine species should be potted in good turfy loam, with 
plenty of drainage. It delights in a damp, shady, warm green- 
house or stove, while growing. It should have a season of rest 
by keeping it moderately cool, but not very dry. I am indebted 
to Mr. Dan. Hanbury for my stock of this plant —IV. W. S.
