I received this interesting and elegant little species from Mr. 
Horne, of Trinidad, who procured the plant in that island. It 
succeeds very well in the warm part of the Mexican house, grown 
on a block of wood with a little moss attached, to prevent the 
tender roots from drying too much. It likes a light and some- 
what airy situation.— W. W. S.
