 Philosophical Journal (6: 331, 1822) where the name Ilabenaria 

 7)iacrophyUa was given to it. Subsequently in his Exotic Elora, Dr. 

 Hooker published an excellent plate of Habenaria Hookeri under the 

 name //. orbiculaia (Pursh) and in an elaborate note indicated the 

 differences between this plant and Goldie's 77. marrophylla, prompted 

 to do so, presumably, by a letter which he had received from Dr. 

 Torrey. "It is," he writes, "with much surprise I find that my friend 

 Dr. Torrey of New York, in a letter which he had the goodness to 

 write to me upon the subject of Mr. Goldie's paper, considers the 77.

 differences between these two plants are fully and satisfactorily pointed 

 out in the Memoir in question. It will suffice here to mention, that 

 H. macwphylla is twice the size of the present individual in almost all 

 its parts, and that the anther is at each angle at base, prolonged into a 

 projecting horn." About fifteen y(^"ars later in Flora IJoreali- Ameri- 

 cana (2: 197) Hooker corrected the treatment of the Exotic Flora, 

 and reduced 77. macropliylla to a synonym of 77. orbiculata with the 

 following explanation: "This fine species, having been but ill defined 

 b^' its first describer (Pursh), has been much misunderstood, and the
