This species resembles Zygadenus elegans Pursh {=Z. glaiLCiis Nutt.) of 

 the North-America, but the flower is smaller, the leaves are narrower and 

 not glaucous, the stem is lower, and the pedicel is shorter. The bracts 

 closely resemble those of Helonias glaherrima Sims Bot. Mag. tab. 1680, 

 which is referred to Zygadenus Fremonti Torr. in Index Kewensis, and to 

 Anticlea glaitca Kunth { = Z. glauciis Nutt.) by Kunth in his Enum. PL 

 IV. p. 192. It apparently differs from Zygadenus sibiricus (Linn.) Gray, 

 an Asiatic species. This genus is new to the Flora of Japan.
