CHENOPODIUM CARINATUM ON CAPE Cop.— In Ruopona, Febru- 
ary, 1911 (Vol. 13, No. 146, p. 22) Mr. Frank S. Collins notes the col- 
lection of Chenopodium carinatum R. Br. in Eastham and Truro, Cape 
Cod, which appears to be the first report of this plant in New England. 
Mr. Collins has given in his article a good description of the plant 
which need not be repeated here and the object of this note is to put 
on record some additional information regarding it. 
I find in my herbarium specimens collected in Wellfleet, August 2, 
1886 and August, 1887 which I took to be immature Chenopodium 
Botrys L. and labeled accordingly, thus showing that the plant has 
been on Cape Cod for at least twenty-seven years. 
The only other report of this species in the United States that I have 
been able to discover is in Watson's Botany of California in which it 
is said to have been introduced from Australia. That it should have 
jumped across the continent from the Pacific coast to the Atlantic is 
one of the mysteries of plant distribution but being a rather inconspic- 
uous and weedy herb it has been doubtless overlooked in other locali- 
ties. In its younger stages it closely resembles Chenopodium Botrys 
and as I have passed it by as this species other collectors may have 
done the same. 
In September of the present year I looked up the occurrence of the 
plant in Truro and found it abundant along a road and spreading 
down to a saltmarsh beach. It was also very abundant as a weed 
in an orchard a half-mile away.— W. P. Ricu, Boston, Massachu-

A SECOND EDITION OF BRITTON AND BRoww's ILLUSTRATED FLORA.— 
The general plan of Britton and Brown’s Illustrated Flora is so fami- 
liar that a review of the second edition ! must of necessity be a com- 
parison with the first. In both editions the greater part of the specific 
descriptions and the figures are identical. Aside from the introduc- 
tion of 504 species which were not in the first edition and are now 
mostly interpolated with only a few words of comparison, the revision 
has consisted in large part of putting into practice Dr. Britton’s 
recently expressed view in regard to the status of the subspecific cate- 
gories,— the subspecies, variety and form. As expressed in the pre- 
face to the new edition of the Illustrated Flora (p. vii) his view is that
