 Diervilla trijickt, Pellaea gracilis, Phegopferis Bryopferis, P. polypodioideSy 

 Woodsia Ilvensis and W. obtusa. The Cornus stolonifei'a is common 

 throughout the region. The Neraopanthes fasicularis occurs sparingly 

 in the marshes. The Rhus venenata is also not infrequent in tamarack 

 woods. The Cypripedium pubescens formerly was abundant in one of 

 the upland woods surrounding the bog. Here as elsewhere in this 

 western country many of the rarer native plants are disappearing. In 

 western Wisconsin there are many areas not suited for cultivation, but 

 all available ground has been utilized, and ground that has not been 

 utilized for cultivation is so closely pastured that many of our more 

 delicate plants cannot survive the hard usage.

The Wild Flower Preseryation 



Society 



ANNUAL REPORT OF THE BOARD OF MANAGERS. 



To the Members : — The Society was organized in New York City on 

 April 23, 1902, and hence has been in operation considerably less than 

 one year. Nevertheless it has made gratifying progress in the dissemi- 

 nation of information concerning our aims and methods, by means of 

 public lectures and addresses and by the circulation of literature. 



The active work of the Society began with an illustrated lecture by 

 Dr. N. L. Britton in the United States National Museum on May 22, 

 the topic being " Some Wild Flowers in Need of Preservation." Many 

 colored lantern slides were exhibited, and the impression made on the 

 large audience by Dr. Britton's arguments was evidenced by the exten- 

 sive membership enrollment. As this report goes to press, arrange- 

 ments are being made for a lecture on "Vanishing Wild Flowers," by 

 Mr. Charles L. Pollard, the Secretary of the Society, at Johns Hopkins 

 Universitj^ in Baltimore, and at the Academy of Sciences in Philadel- 

 phia. A public meeting was held in Pittsburg July 3, in connection 

 with the sessions of the American Association for the Advancement of 

 Science, addresses being made by Professor Charles E. Bessey, Pro- 

 fessor S. M. Tracy, Mrs. N, L. Britton and others. Full reports of these 

 affairs have appeared from time to time in The Plant World. 



There has been an extensive distribution of printed matter. The 

 prize essays of Dr. Knowlton and Dr. Grout on " Wild Flower Preserva- 

 tion," reprinted from the Journal of the New York Botanical Garden,
