254 BOTANICAL GAZETTE [SEPTEMBER 
Lawrenceville, Lawrence County, Illinois, Dr. J. Schneck, October 15, 
1895 (type) (see Sargent, Silva N. Am. 7:138). A tree believed to have been 
of the same parentage was found at about the same time by Mr. F. REPPERT 
near Muscatine, Muscatine County, Iowa (see TRELEASE in Rep. Mo. Bot. 
Gard. 7:39. pl. 23. figs. 2-5) 
Carya Nussbaumerii, n. hyb. (Carya laciniosaX pecan).— 
Leaves 7~9-foliolate; petioles and rachis puberulous; leaflets lan- 
ceolate, long-pointed and acuminate at apex, rounded and unsym- 
metrical at base, pubescent on the lower surface, the terminal 
petiolulate, the lateral nearly sessile. Fruit oblong, narrowed and 
rounded at base, acute at apex, puberulous and more or less thickly 
covered with yellow scales, about 7 mm. long and 3.5—3.8 cm. in 
diameter; involucre splitting nearly to the base and 4 mm. in 
thickness. Nut oblong, compressed, only slightly angled, short- 
pointed at apex, rounded at base, 6 mm. long, 3.5 cm. wide, and 
2.5 cm. thick, with a shell 1.5—2 mm. in thickness. 
I suggest this name for the Nussbaumer hybrid (see SARGENT, Silva N. 
Am. 7:158. pl. 349. fig. 4; TRELEASE in Rep. Mo. Bot. Gard. 7: i pls. 22, 
23. figs. 7-9). 
This tree was first found on the bottoms between Mascoutah and Fayette- 
ville, St. Clair County, Illinois. A tree producing a similar nut which came 
originally from Illinois was cultivated before 1892 by Mr. R. M. Fioyp of 
Cedar Rapids, Iowa, and has been called the Floyd nut. In October 1895 
Dr. ScHNEcK found a tree producing similar fruit at Mt. Vernon, Posey County, 
Indiana. Grafted plants of this tree, which has been called the McCallister 
(see Nut culture in the United States, Bull. U.S. Dept. Agric., Div. of Pomol- 
ogy, 1896, 63. pl. 9. fig. 6), were sent to Washington, Georgia, whence this tree 
was distributed as the Washington nut, a name now abandoned by pomolo- 
gists. Another of these trees has been reported from the neighborhood of 
Burlington, Des Moines County, Iowa, and another, known as the Rockville 
nut, from near Rockville, Bates County, Missouri. In its foliage and in the 
color of the branchlets this hybrid resembles C. laciniosa. The branchlets, 
however, are not as stout and are less pubescent than those of that species, 
and the buds are smaller and more acuminate. The fruit in shape resémbles 
that of the pecan, but does not have the sutural wings of that species, and the 
nut is white or nearly white and only slightly streaked with brown. 
Carya Dunbarii, n. hyb. (C. laciniosa Xovata).—I suggest this 
name for a number of trees found growing on the bottoms of the 
Genesee River at Golah, Monroe County, and Mount Morris,
