April 1908] William Ashbrook Kellerman 51 



the United States, he was elected Professor of Botany in the 

 State Agricultural College at Lexington, Kentucky. Later he 

 accepted a similiar position in the Kansas State Agricultural 

 College, where he remained seven years. During four years of 

 this time he was Kansas State Botanist. In 1891 he came to 

 the Ohio State University as Professor of Botany, which posi- 

 tion he held up to the time of his death. 



Every moment of time which was not consumed in regular 

 class and laboratory work, was devoted to collecting material for 

 herbaria, so that wherever he was located he built up a con- 

 siderable memorial in the shape of either newly inaugurated 

 or largely increased herbaria. Noteworthy among these are 

 the Kansas State herbarium at the Kansas Agricultural College 

 and the Ohio State herbarium at the Ohio State University, 

 which is so complete that the distribution of the flora of Ohio 

 may be determined with considerable accuracy by simply con- 

 sulting the index to this herbarium. His own private herbarium 

 of flowerng plants numbers 30,000, and his herbarium of para- 

 sitic fungi is second to none in the country. 



His "Ohio Fungi Exsiccati" is an unusually fine series of 

 herbarium specimens which were distributed to the leading herb- 

 aria of Europe and America. He had also begun the distribu- 

 tion of Guatemalan species, the first decade of which appeared 

 in November, 1906, under the name "Fungi Selecti Guate- 

 malenses." 



Numerous new species have been described by him. and a 

 genus and various species have been named in his honor* which 

 will in the future mutely testify to the high esteem in which he 

 was held by his fellow botanists. 



For the World's Fair in Chicago, in 1893, ^^- Kellerman 

 prepared the Forestry Exhibit of the State of Ohio representing 

 every tree indigenous to the state. The exhibit showed twigs, 

 leaves, flowers, fruit, cross-section of trunk, lengthwise section, 

 split surface, and bark. 



For this collection he was awarded a Columbian Exposition 

 medal and diploma. The work of preparation was done for 

 the love of it and upon condition that, after the close of the 

 exposition the entire exhibit should become the property of the 

 Ohio State University. He, himself, felled many of the trees.
