 ^^ which that important function is in this plant performed, is

 curious genus I beg to affix the name of Professor Charles 

 Morren of Liege, the discoverer of the manner of cultivat- 

 ing Vanilla, so as to make it produce with certainty a crop 

 of its aromatic fruits, and one of the most distinguished 

 Vegetable anatomists of the present day.
