CAREX MARITIMA IN MARSHFIELD, MassacHUSETTS.— On July 4, 
1914, Judge J. R. Churchill and I found specimens of Carex maritima 
O. F. Mueller, growing in the landward edge of the salt-marsh near 
the Marshfield station. The plants were small, not over half the size 
of the average specimens I have seen on the Maine coast. This is a 
southward extension of range of about thirty miles. The southern- 
most station given by the Local Flora Committee is Cambridge.—

CAREX LEPTONERVIA A VALID SPECIES.— Since the publication 
of the northernmost representative of Carex laxiflora Lam. as C. laxi- 
flora, var. leptonervia Fernald, RHopora, viii. 184 (1906), the writer 
has watched the plant with great care both in the field and in the her- 
barium and has found it so constant in its characters and so pronounced 
in its range that he is satisfied that it is a Canadian species quite dis- 
tinct from the more southern complex comprising C. laxiflora and the 
other plants which are often placed with it as varieties. In all these 
southern plants, which reach their northeastern limit in New England 
or adjacent Canada, the perigynium is strongly nerved, but in C. lepto- 
nervia the smaller perigynium is nerveless or essentially so. The 
latter plant, as originally indicated, belongs to a rather northern area,
