JUGLANDACEAE OF THE UNITED STATES. 33 
The fruit of the Pecan is one of the most variable nuts, 
some specimens being narrowly oblong while others are 
almost as broad as long. At the base, the commissure 
usually bears a delicate wing at each side, — an approach 
to the 4-celled base of other hickory nuts. The deeper 
color and conspicuous gloss of nuts from certain sections as 
they appear in the market does not indicate any botanical 
difference, but is the result of treatment which they under- 
go before being offered for sale. 
In 1894, Mr. S. J. Galloway reported sweet-fruited nuts 
obtained from a single tree near Eaton, Ohio, which he 
believed to bea hybrid of the Pecan with some other species.* 
Of this tree, which appeared spontaneously some twenty- 
five yards from a cultivated Pecan, Mr. Galloway has been 
kind enough to send me ample flowering and fruiting speci- 
mens and twigs, which show that it resembles the Pecan in 
foliage and in the general form of the fruit and the char- 
acter of the kernel, while it differs in having the staminate 
catkins stalked, as in other hickories, and in the nut, which, 
while elongated, is somewhat flattened, broader upwards, 
slightly marked by low-rounded prominences as in #. 
minima, acuminately pointed, only a little dark mottled, and 
evidently 4-celled for about 6 mm. from the bottom of the 
cavity. The twigs are slenderer than is usual in the Pecan, 
and nearly glabrous, and the slender buds are all conspicu-. 
ously yellow dotted.—PIl. 16, f. 12-14, 20. 
Mr. F. Reppert, of Muscatine, Iowa, has also placed in 
my hands specimens from several trees found near that 
city, which in aspect resemble the Bitternut, and in twig 
and bud characters approach the Galloway tree. The nuts, 
also, in shape and striping are more or less like the broader. 
forms of Pecan nuts, though they are thinner shelled and 
4-celled to a greater height, while the kernel is somewhat 
astringent.— Pl. 16, f. 15-16. 
On the whole, the characters of these trees are inter-
