JUGLANDACEAE OF THE UNITED STATES. 33 
The fruit of the rocun is one of the most variable nuts, 
some s[)ecimens beintr narrowly oblong while others arc 
almost us broad as lonir. At the base, the commissure 
u>ually bears a delieate wiuir at each side, — an approach 
to the 4-celled ba.M^ of other hickory nuts. The deeper 
they ap[)car iil tlu- markn docs not indirMtc any botanical 
difference, hut is the r.-ult 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 
believedtobeahybridof the Pecan with some otherspecies.* 
Of this tree, which appeared spontaneously some twenty- 
tiv^e yards from a cultivated Pecan, Mr. Galloway has been 
kind enough to send me ample flo^ve^ingand 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 tlattened, broader upwards, 
slightly marked by low-rounded prominences as in //. 
minima, acuminately pointed, only a little dark mottled, and 
evidently 4-celled for about 0 nun. 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.— PI. 16. f. 12-14, 20. 
Mr. F. Reppert, of Muscatine, Iowa, has also placed in 
my hands specimens from several trees ft)und near that 
city, whitrh in aspect resemble the Bittornut, 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.— PI. 16, f. 15-16. 
On the whole, the character.- of these trees are inter-
