OBSERVATIONS ON THE FLOWERING PLANTS, FERNS, AND 

 FERN ALLIES ON AND NEAR THE SHORE OF LAKE HURON 

 FROM LINWOOD PARK NEAR BAY CITY, BAY COUNTY, 

 TO MACKINAW CITY, CHEBOYGAN COUNTY, INCLUDING 

 THE VICINITY OF ST. IGNACE, MACKINAC AND BOIS 

 BLANC ISLANDS, MACKINAC COUNTY, MICHIGAN. 



Through a suggestion of the late Professor C. A. Davis, the writer 

 for a number of years had contemplated a botanical examination of the 

 eastern part of the lower peninsula of Michigan along the lakes and 

 their connecting waters from the southern state line to Mackinaw City 

 in Cheboygan County. The opportunity to begin was offered in 1908, 

 under the direction of Dr. A. G. Ruthven while making a biological sur- 

 vey of the sand dune region in Huron County on the south shore of 

 Saginaw Bay. During that year and in 1909 the whole shore line and 

 vicinity of Huron County and nearly all the islands in Saginaw Bay r 

 were carefully examined, the results reported and published.* In 1910 

 an examination of the Saginaw Bay shore was extended west to tin 

 border of Bay County and most of Tuscola County looked over. The 

 plants noticed have been catalogued but not published. In 1911 it was 

 decided that a botanical survey of the Lake Huron Shore farther north 

 was desirable, provision made for it, and the work begun in June 1912 

 and followed up from time to time to and including a part of 1914. 



Ground Traversed 



The work was begun June 18, 1912, at a point two miles south of 

 Lin wood Park in Bay County, going northward as near Lake Huron as 

 possible. Much of the journey was made over new and almost impass- 

 able roads near the lake, plent} r of time being taken to examine the 

 vegetation. Stops and examinations were made at the following plac 

 in 1912, and the country examined about and between them: Linwood 

 and Pinconning, Bay County; Omer and Au Gres, Arenac County; 

 Tawas City, Oscoda and Au Sable, Iosco County; Harrisville, Alcona 

 County; Alpena, Alpena County; Rogers, Presque Isle County; Che- 

 boygan and Mackinaw City, Cheboygan County; St. Ignace and Macki- 

 nac Island, Mackinac County. Afterward in 1913 many of these places 

 were revisited and in addition, Bois Blanc Island and Round Island, 

 Mackinac County; Hillman, Atlanta, and Lewiston, Montmorency 

 County; Mio, Oscoda County; and Rose City, Ogemaw County. The
