mediate between the Pecan and Bitternut {H. minima), and 
they seem clearly to be hybrids of those species. The 
husk in most cases is intermediate in thickness between 
the two assumed parents, Hickorea Texana, Leconte* 
seems to be a similar hybrid, and the figure published by 
Leconte in his article represents quite well some of the nuts 
referred to above. Dr. Mohr f has reported the Pecan as 
hybridizing with the Water Hickory, but I have seen no 
specimens indicating this hybrid. The Pecan further 
hybridizes in an interesting way with the Mocker Nut and 
the Bottom Shellbark, under which species the hybrids are 
considered.
