Introduced Species, etc. 



A. vineale, Linn., is frequent in the Atlantic States, and is often 

 mistaken for A. Ganadense. It may be readily known by its leafy 

 stem, terete leaves, and cuspidate filaments. 



A. Carolinianum, Red., is referred by Regel to A. blandum, prob- 

 ably correctly. It is not known in America. 



A. Macnabianum, Regel (Gartenfl. 1874, 264, t. 770, fig. 2, 3), 

 cultivated from bulbs probably collected in Oregon, cannot be identi- 

 fied from the description in Regel's Monographia Alliorum.
