For this highly curious parasite, the public is indebted 
to his Excellency Sir Ralph Woodford, Governor of 
Trinidad, by whom living plants haye been sent to several — 
collections in this country. The plant from which our 
drawing was taken flowered in a stove at Mr. Colvill’s 
Nursery, last March; but not in perfection, the blossoms 
in our only native specimen having a diameter nearly twice 
as great as is represented in the accompanying figure, 
and being much more completely expanded.
