1918] SARGENT—CARYA 255 
Livingston County, New York, by JoHN DuNnBAR, assistant super- 
intendent of the parks of the city of Rochester, New York. These 
trees, which have at different times been considered both C. laci- 
ntosa and C. ovata, vary among themselves in the color and pubes- 
cence of the branchlets, in the size of the buds, and in the size and © 
shape of the fruit and nuts. The leaves have the 7 or 9 leaflets of 
C. laciniosa, but the leaflets are usually narrower than those of that 
species and less pubescent. I have selected no. 68 Dunbar, Sep- 
tember 19, 1911, as the type of this hybrid, as the tree is still stand- 
ing and can easily be located. 
Leaves 7-foliate, the petioles and rachis slender, glabrous; leaf- 
lets acuminate, puberulous on the lower surface and pubescent on 
the under side of the midribs, the terminal oblong-obovate, cuneate, 
and gradually narrowed below into a slender petiolule 1.5 cm. in 
length, the lateral lanceolate to oblanceolate, nearly sessile. Fruit 
oblong, rounded at ends, glabrous, 4 cm. long, 3 cm. in diameter; 
involucre splitting to the base, 5 mm. in thickness; nut oblong, grad- 
ually narrowed and rounded at base, acute at apex, compressed, 
conspicuously ridged to below the middle, pale brown, 3 cm. long, 
2.5 cm. wide, and 2 cm. thick. 
A tree 80-90 ft. high, with light gray scaly bark, stout spreading branchlets 
puberulous early in the season, glabrous and pale red-brown in the autumn. 
Terminal buds, oblong, acute, 1. 5-1.8 cm. long and 6-7 mm. in diameter, the 
outer scales dark red-brown and puberulous. 
Golah, Monroe County, New York, J. Dunbar, September 19, IgIt 
(no. 68, type). 
No. 71 Golah, collected by J. Dunbar September 19, ro11, has 
the leaves in the size and shape of the leaflets like those of C. ovata; 
the petioles and rachis are pubescent, and the leaflets are more 
pubescent than those of no. 68. The fruit is oblong-obovoid, com- 
pressed, rounded at base, abruptly acute at apex, 4 cm. long, 3 cm. 
wide, and 2 cm. thick, with an involucre splitting nearly to the 
base and 4 cm. thick. The nut is oblong-obovoid, acute at the 
ends, only slightly angled, and pale in color. 
This tree, which is still standing, is 80 ft. high, with ashy gray 
bark divided into plates but not separating into loosely attached 
scales like that of its supposed parents, and stout reddish glabrous
