This is the plant that has been known in America under the 

 name Luziila cauipcstris or Jwioidcs caiiipcstrc, but this North 

 European species is found, if at all on this continent, only in the 

 extreme northeastern portion. It is distinguished from J. intcr- 

 inedhun by its fewer, larger and nodding spikelets. The name 

 Jiinciis vinltifloms dates back as far as 1791, when Ehrhart i.^sued 

 his set of grasses, sedges, etc., but as far as can be ascertained, it 

 was never published for this plant before 1800, in the revised 

 edition of Hoffmann's Flora.

Mr. House * has shown that Ibidium Salisb. is the name that 

 properly should be used for Spirantlics Richard and Gyrostacliys 

 (Pers.) Kuntze ; OpJirys L. for Listcra R. Br. and Cytherea Salisb. 

 for Calypso Salisb. The Rocky Mountain species of these genera, 

 which have not already been transferred, are given here.
