iculturist for 1884, p. 546,
fol., A. S. Fuller published an account of a supposed hybrid
between this species and the pecan, which has been called the
Nussbaumer hybrid, after J. J. Nussbaumer, of Okawville, Ill.,
who first brought it to the attention of Judge Samuel Miller,
of Bluffton, Mo. Mr. Nussbaumer writes me that the original
tree, which stands in the bottom between Mascoutah and
Fayetteville, Ill., in general appearance resembles laciniosa,
though the bark is intermediate between that of the Pecan and
Mockernut. Prof. Sargent states (Silva, vii, 158) that a small
tree grown from this in New Jersey, by Mr. Fuller, cannot be
distinguished from laciniosa of the same age; and I should
hardly be able to distinguish an imperfect twig from a small
tree, cultivated by Judge Miller, from laciniosa. The nut,
however, is very peculiar, being more elongated than is usual
in that species, and widened upwardly, less acutely angled "as
if the ridges had been sandpapered down," and so thin-shelled
that it can be crushed easily by pressing two together in the
palm of the hand. A somewhat similar nut, originally from
Indiana, was described by Mr. Fuller In the New York Weekly
Tribune, July 9, 1892 (Sargent's Silva, l.c.), as cultivated by
R. M. Floyd, of Cedar Rapids, Iowa. And in the autumn of 1895,
Dr. J. Schneck sent me ample fruit, twig and leaf specimens of
a similar hickory from Posey county, Indiana. The nut of this
last is almost identical with a specimen of the Nussbaumer nut
in the Englemann herbarium, while its twigs closely resemble
those of laciniosa, and the leaves are decidedly of the pecan
type. I am led to the conclusion, therefore, that these several
forms really represent hybrids between H. pecan and H.
laciniosa. In size, quality, and thinness of shell they appear
to be the most valuable of American nuts. (Trelease, Wm., 7th
