HERBARIA CONSULTED. 



The following Herbaria have been examined: 



The Herbarium of the State Agricultural College is fortunate in pos- 

 sessing the collection of Dr. D. Cooley, an excellent botanist who lived 

 many years in Washington, Macomb county. He was a valued correspond- 

 ent of Dr. Gray, Dr. Torrey, W. S. Sullivant and other botanists of the 

 early part of this century. 



The Herbarium of Dr. D. Clark, of Flint, Mich., has lately become the 

 property of the State Agricultural College. This collection contains sets 

 of Bebbs' Willows, Olney's Carices and many specimens from the earlier 

 American collectors, besides valuable collections of Michigan plants. 



The large collection of Prof. C. F. Wheeler, which was destroyed by the 

 burning of the Botanical Laboratory on the 23d of March, 1890. 



Prof. V. M. Spaulding kindly permitted us to examine the University 

 Herbarium at Ann Arbor, in which are deposited the collections of Dr. 

 Douglass Houghton, 1838; Miss Mary H. Clark, Miss E. C. Almendinger, 

 Prof. M. W. Harrington, Prof. N. H. Winchell, Geo. L. Ames, M. D., F. 

 E. Wood and others.

 Grand Rapids under the charge of Mr. George D. Sones.

 of Alma College; also Prof. Davis' collection.
