black and very soft under the action of frost; kernel very oily, of some- 
what rank flavor. 
2. Fruit ovoid, much smaller than in number 1. Nut following shape 
of hull; hull relatively thin, bright green in immature state, turning yellow 
upon ripening or under the influence of frost; pulp drying up and harden- 
ing at maturation; kernel dry (not markedly oily), and of an agreeable 
flavor. This is the form which the wood-wise boy gathers for his winter 
supply. 
The leaf of form 2 is much smaller than that of form 1, the leaflets 
being smaller, more sharply acute and finely serrate; they are also much 
less vividly green than those of form 1, a difference in color that seems 
due to the thicker epidermis. 
Form number 2 grows in drier situations than form 1, though occa- 
sionally extending into the regions of the latter. In these cases there 
seems to be no blending of forms. The two forms are sharply distinet 
wherever associated. 2 
Lumbermen assert that the wood of form 2 is much lighter in color 
and of much less commercial value than that of form 1. Whether or not 
there is difference in the period of flowering and maturation of fruit 
I am unable to state. Form 1 is that of ordinary descriptive botanists, 
form 2 not being noted or indicated. In our area it is of general occur- 
rence and is known by the boys as the “‘little black walnut.” 
Form 8, so far as I know, is found only in a few localities near La- 
fayette. The fruit closely resembles the English walnut in some particu- 
lars, while in others it resembles the butternut. The hull is thin and 
without appreciable pulp at any season. The shell is very thin, the nut 
cracking as easily as the English walnut. The kernel is not at all oily 
and is very sweet. Some few trees are found upon the west bank of the 
Wabash River near Lafayette, and a few others near the Purdue campus. 
This form I described before the Academy of Science in 1890 under the 
title of “An Aberrant Form of Juglans nigra.’ In that paper I suggested 
the fruit peculiarity was due to an early defoliation of the trees which 
occurred that year. Observations continued from that time until the 
present convince me that the opinion there expressed is not borne out by 
facts. The form has maintained itself in the stations indicated through 
these years from 1890 to 1900, its fruit always presenting the features 
given above. Dr. Schneck suggests that it is a hybrid of J. cinerea x J. regia 
in which he follows J. Robinson in “Our Trees” (published by the Essex
