 dependeniibus ob labellmn posticum. Labellum siibcomyresum, carnosum, 

 lobo apicis rotundato incurvo, lateralibus cilia, (enui, denticidutd tamen,

First introduced by Mr. Bell Edward Lloyd, who sent it 

 from Brazil to Miss Falkner of Fairfield, about 8 or 9 years 

 ago. More recently it has been transmitted to Mr. Harrison 

 of Liverpool by Dr. Dundas, an eminent medical gentleman 

 residing at Bahia. 



It is not so shewy as C. tridentatum, but it is peculiarly 

 fragrant, a quality which all the other known species are 

 destitute of. It requires the same treatment ; and when in 

 rapid growth will thrive the better if its roots are actually 

 allowed to immerse themselves in water. 



Our specimen was communicated to us by Mr. Harrison 

 in February last.
