So soon as the curious flowers were fully expanded, Mr. 

 Harrison, with his usual kindness, forwarded me a speci- 

 men ; together with an excellent drawing from the pencil of 

 Mrs. Arnold Harrison. This is, in part only, copied, to 

 suit the plate of the Magazine ; and therefore but imper- 

 fectly represents the stately appearance of the original. 

 For this species is no less remarkable among Orchideous 

 plants for its stature, than for its large and copiously flow- 

 ering spike. 



Being unable to find any Genus of the Orchide^e which 

 corresponds with it, 1 have ventured to give it a Generic 

 name significant of the dove-like appearance of the column 

 of fructification. 



It is to be hoped, now that Mr. Harrison has so success- 

 fully cultivated this rarity from the tropical parts of America 

 bordering on the Pacific, that Mr. Barnard will further the 

 cause of Science by collecting and introducing to our stoves 

 other plants of the same family, and which bear a long 

 voyage better than many less interesting tribes.
