The American plant is specifically distinct from C, leporhiay 

 L. Steudel founded his C, Preslii upon the description of Presl's 

 C. Icporina, The orginal does not exist, either in the collection 

 of Presl or Steudel, but I adopt Steudel's name in lieu of any 

 other. C, pciasatciy Dewey, SilL Journ, (I), xxix, 246 (1836), 

 referred here by Boott, cannot be pressed into service. The ori- 

 ginal sheet is in Herb. Torn It contains three plants : C. lagopina, 

 Wahl., C. festiva, Dewey, and C. Liddoni, Boott, to all of which 

 Dewey's description will equally apply.

The confusion into which Boott's Carex aperta has fallen is 

 ex'plained in Bot. Gaz. xiii. 84 (1888), and the opinion there ex- 

 pressed that the species is confined to our northwestern coast is 

 verified by an examination of Boott's material. The plant referred 

 to C. aperta in the Eastern States is C. stricta, var. decora, Bailey,

Bennett, Croydon, England, and a study of the specie's in various 



foreign herbaria, have enabled me to draw lines of separation 



between the European plant and the western plants which have 



been referred to it. C. actitina differs from C. acuta in the pale 

 color of the plant and its lesser size and thin leaves, habitually 

 smaller spikes, thinner and shorter perigynium, which is much less 

 prominently nerved, and the hghter colored obtuse or muticous 

 scales. Oregon, Hoivell 935, Hendersoft; British Columbia,
