In dealing with the various closely allied plants which by some ° 
authors have been treated as species and by others as varieties of 
Carex salina Wahl., the latest author to study the group (Kiiken- 
thal, Pflanzenreich 4”: 361-363) has pointed out that the name 
Carex cuspidata Wahl. is not applicable to the plant found on the 
northeastern coast of this continent. The name to be taken up 
for this plant is Carex recta Boott, or if one prefers a varietal name 
the pleasant-sounding name given in the synonymy above is open 
to him. 
In this connection it may be pointed out that Carex lanceata 
Dewey (Am. Journ. Sci. 29 : 249), referred by Kiikenthal, follow- 
ing Boott, to Carex salina as a variety, is probably a mixture of 
Carex livida (Wahl.) Willd. and Carex salina Wahl. The original 
collection in the Torrey herbarium is mixed and contains both 
species, and the description applies in part to both species, while 
Dewey compares the species to his Carex Grayana (a synonym of 
Carex livida). The plate (a poor one) is of Carex salina, but it 
does not agree with the description. 
CAREX ATLANTICA Bailey, Bull. Torrey Club 20: 425. 1893 
In Professor Fernald’s very able paper on the Northeastern 
Carices of the Section Hyparrhenae (Proc. Am. Acad. 38: 447 ef 
Seq.) there is very little to which one can take exception, but on 
the contrary a careful study of the group treated leaves one very 
largely in accord with the treatment given. However, in identify- 
ing Carex sterilis Willd. with C. atlantica Bailey it seems to the 
present writer that a mistake was made. The grounds for this 
view are the following :
