Messrs. Loddiges, with whom it flowered imperfectly three 
or four years ago. Other and more healthy plants were 
afterwards presented by Mr. Lance to the Horticultural 
Society, the produce of one of which was the singular raceme 
now represented. 
In size the flowers of this plant are the largest that have

but they compensate in fragrance for their want of brilliant 
colours: the purest odour of Vanilla is exhaled by them

seems to require the greatest heat that is ever obtained 
in a damp stove. It is disposed to increase itself pretty
