218 Plants collected during a journey 



Corolla reflexed, pale, greenish purple ? Segments oblong. Leaflets of the 

 nectary spreading, cucullate, bidentate. Horns subulate-falcate, project- 

 ing beyond the antheridium. 



Hab. On the Canadian ? 



Obs. As there was but a solitary specimen of this plant, 

 and that destitute of lower leaves, I have considered it only 

 as a variety of A. obtusifolia, though it is probable that future 

 observations will prove it to be a distinct species.
