such instances have come to the writer's attention. At least one 

 other instance has been reported previoush' .-•- In Ottawa county 

 three years ago a good sized bush of Salix 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 

 anient 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 Salix Candida, 

 at Castalia, the past sununer, which had two carpellate aments 

 just about at anthesis in July. These were normal and ordinar}- 

 in every way except in being borne on leafy branches. Near 

 Big Darby creek, in Franklin county, two plants (carpellate) 

 of Sa/ix cordata were found in August, full of blossoms. The 

 two were about a hundred feet apart and entirely unconnected. 

 Why they should both be blooming at the same time is very 

 peculiar — one of the interesting things which have 5-et 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 )iigra, for 

 instance, flowering a second time. In each case, except the 

 reported instance of Sa/ix Iiuiui/is, the flowers were carpellate. 

 This may 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 waj'. Rather one would expect the 

 staminate aments to furnish the most frequent examples because 

 they seem to develop first in the spring.

POISONOUS AND OTHER INJURIOUS PLANTS OF 



OHIO. 



John H. Schaffner. 



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 ho])e that it may be of service to those 

 who wish to make a study of the subject. The list is believed to 

 be fairly complete except the thallophytes, where only a small 

 number of the most important Fungi have been included. 



I am under ver}^ great obligation to Mr. \'. K. Chesnut, of the 

 U. 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 s]:)ecies. I wish here to express my thanks 

 and appreciation of his invaluable a.ssistance and criticism.
