such instances liave come to the writer’s attention. At least one 
other instance has been reported previously.* In Ottawa county 
three years ago a good sized bush of Sa/ix discolor was found with 
many catkins in August. They are not normal but much whiter 
than ordinary pussies, and many of the capsules are aborted. At 
Washington, late in the summer of 1902, a solitary carpellate 
ament was found at the tip of a leafy branch of .Sa/ix scricca. 
This lone catkin was of normal appearance but about ready 
to drop off when noticed The third was a plant of Sa/ix Candida, 
at Castalia, the past summer, which had two carpellate aments 
just about at anthesis in July. These were normal and ordinary 
in ever\" way except in being borne on leaf}’ branches. Near 
Big Darby creek, in B'ranklin county, two plants (carpellate) 
of Sa/ix corda/a were found in August, full of blossoms. The 
two were about a hundred feet aj)art and entirely unconnected. 
Why the}’ should both be blooming at the same time is very 
peculiar — one of the interesting things which have yet to be 
explained or chance. 
All these instances are from among the species which flower 
earliest in the spring and hence develop their flowers furthest in 
the fall. It would be quite surprising to find Sa/ix nigra, for 
instance, flowering a second time. In each case, except the 
reported instance of Sa/ix /iinni/is, the flowers were carpellate. 
This ma}' be mere coincidence. It is difficult to see what reason 
there could be that the carpellate flowers should be especially 
liable to be affected in this way. Rather one would expect the 
staminate aments to furnish the most frequent examples because 
they seen; to develop first in the spring.

POISONOUS AND OTHER INJURIOUS PLANTS OF 
OHIO. 
John H. Sch.\ffnek. 
In the following catalogue of plants an attempt has been made 
to furnish students with a convenient reference list of the injuri- 
ous plants of Ohio, in the hope that it may be of .service to those 
who wish to make a study of the subject. The list is believ’ed to 
be fairly complete except the thallophytes, where only a small 
number of the most important Fungi have been included. 
I am under very great obligation to Mr. V. K. Chesnut, of the 
Ik S. Department of Agriculture, who has kindly added a large 
number of plants to the original list and furnished many of the 
notes given under the species. I wish here to express my thanks 
and apjM'eciation of his invaluable assistance and criticism.
