was discovered by Humboldt and Bonpland in the beginning 

 of the century. There is a fine suite of specimens of it in 

 the ' Hookerian Herbarium,' collected by Triana, Linden, 

 Spruce, Fendler, and Goudot. The Eoyal Gardens are in- 

 debted to Mr. Bull, F.L.S., for the specimen here figured, 

 which flowered in a stove in July of the present year.
