Of these 195 species and varieties of Carex 61 are Vigneae 
and 128 Carices genuinaeC) The grex richest in species is 
Microrhynchae with 27, alter which follow Melananthae with 15, 
Äeorastachyae with 14, Äthrostachgae with 15, Pkysocarpae with 9, 
Brach y st ach ijae, Neuro chlaenae, AcantJiophorae and SiAiaericliophorae 
each with 7. 
1) In Mr. Ho well’s Flora of Northwest America the following species are 
enumerated: C. anguatata Roott (Wash.), Barbarae Dew. (Oregon), Irunnes- 
cens Poir. (Oreg.), deflexa \iornQ,m. (Oreg. Alaska), All (Wash.), Tietero- 
neura W. Boott (Idaho), nudata Boott (Oreg.) riparia Curt. (Idaho), Tolmiei 
Boott (Oreg.) and vallicola Dew. (Idaho). We have seen no specim.ens of 
these, and have not ventured to add them to our list since the Identification 
seems doubtful. — We have, furthermore, omitted C. Idaboa Bail., since the 
systematic position of this interesting species is uncertain; it may belong 
to the Melananthae.
