LINN^VS AND AMERICAN BOTANY^ 



I HAVE been asked to make a short ad-

 most able one to deliver such an address, 

 for there are many abler men present, but 

 simply because I was born in the same 

 country as Linnaeus. In fact, my grand-

 daughter, the grandmother of Linnasus. 

 On the Jonsboda farm stood a very large 

 linden tree, so old and with so many tradi-

 for the ministry, it was natural that they 

 should think of this tree in selecting a fam- 

 ily name. They called themselves Tili- 

 ander; Tilia is the Latin for the linden or 

 basswood, and andros the Greek for man. 

 It may not be amiss to state that at that
