CATALOGUE OF PH.ENOGAMnUS AND ACROGENOUS PLANTS FOUND GROWING 



WILD IN THE LOWER PENINSULA OF MICHIGAN AND THE ISLANDS 



AT THE HEAD OF LAKE HURON. 



During the season of 1859, no special botanical assistant was 

 connected witli the survey. As the work of 1860, was to ex- 

 tend into portions of the State less known to the botanist, Mr. 

 N . H. Winchell was selected to accompany the exploring party 

 in the special capacity of botanical collector and assistant, and 

 the following catalogue has been drawn up by his hands. 



The following are the souices from which the materials for 

 this catalogue have been derived: 



1. The observations of the geological parties in 1859 and 

 1860. 



2. The catalogue published by Dr. Wright in the Geological 

 Report of 1838. 



3. The University Herbarium which contains many plants 

 collected after the publication of Dr. Wright's Oalalogue. A 

 list of these plants was made out at my request, and the whole 

 collection arranged by Mr. E E. Baldwin. 



4. The catalogue prepared by W. D. Whitney, of plants ob- 

 served in the Lake Superior Land. District, and published in 

 Poster and Whitney's Report, vol. ii. 



5. The notes of Miss Mary Clark, of Ann Arbor, an enthusi- 

 astic botanist and collector from various parts of the State. 



6. A collection of plants made in the neighborhood of Fort 

 Gratiot, near the foot of Lake Huron, by Mr. E. P. Austin, As-
