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

 name Luzula campcsiris or fun oid.es campestre, but this North 

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

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

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

 /uncus multijlorus dates back as far as 179 1, when Ehrhart issued 

 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 Spiranthes Richard and Gyrostachys 

 (Pers.) Kuntze ; Ophrys L. for Listera R. Br. and Cytherea Salisb. 

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

 which have not already been transferred, are given here.
