ON PAPER-SHELL WALNUTS 
given period as either of the parent species. The 
leaves are quite hairy on both sides, even more so 
than those of the Japanese parent. The branches 
are inclined to droop. 
The nuts of the Japanese walnut have an 
exceedingly hard shell. The meat of the nut, how- 
ever, is delicious, perhaps equaling that of any 
other nut, with the exception of some varieties of 
the pecan. But it is very difficult to get the meats 
from the shell, as they are usually broken in 
cracking the nut. 
There is, however, a form of the Japanese wal- 
nut which is so variant that it is sometimes re- 
garded as a distinct species, under the name of 
Juglans codriformis, but which I think not cor- 
rectly entitled to this rank, inasmuch as the two 
forms are closely similar as to general appearance 
and growth. The chief difference is in the nuts, 
which in the cordiformis are usually heart-shaped, 
somewhat similar in appearance to the form of 
the central chestnut where these nuts grow three 
in a burr. The nut is exceedingly variable, not 
only in size but in form and thinness of shell. 
Some individual trees bear nuts that are six times 
as large as those borne on other trees in the neigh- 
borhood. The shell is much thinner than that of 
the Japanese walnut, and the meat is of the same 
excellent quality.
