The PtANT WoRi.D. 



The Indiana tree is growing in a natural open grove of wal- 

 nut, oak and hickory trees. It is probably forty to fifty years 

 old and free from branches to a height of eight or nine meters. 

 The crown is not large and has all the aspect of a Juglans nigra. 

 The bark as well as the leaves are also, superficially at least, 

 walnut in their characters. Growing about thirty meters from 

 this tree are a couple of hickory trees {Hicoria minima, Marsh, 

 Britton) each fully a third younger than the walnut. The pe- 

 culiar nuts were found in 1903, and, according to statements 

 of parties living near, the tree has borne some of these nuts 

 nearly every season since.

 dwelling, though it is probably native, as the immediate vicinity 

 was originally a walnut-hickory-oak woods. It is probably 

 sixty to sixty-five years old and at one time had a large crown, 

 the first branches of which were five to six meters from the 

 ground. Last year the owner of the tree, for some inexpHcable 

 reason, topped it, so that the tree bore no fruit this year. This 

 tree has been in possession of the same family for two genera-
