nut. The branchlets resemble those of the pubescent form of 
C. ovata. 
No. 251 Golah, J. Dunbar, August 31, 1915, has only slightly 
pubescent leaves with leaflets resembling in shape those of C. ovata 
var. fraxinifolia. The fruit is pubescent, subglobose, 3 cm. long 
and rather broader than long, with an involucre 3 mm. in thickness; 
the nut, although less prominently ridged, resembles the nut of C. 
ovata. The branchlets are reddish brown and puberulous. 
No. 252 Golah, J. Dunbar, August 31, 1915, has the leaves of 
C. laciniosa, oblong pubescent fruit 3 cm. long, with an involucre 
5 mm. in thickness and conspicuously angled nuts. The branchlets 
are stout, dark red-brown, and densely pubescent. The terminal 
bud is about 1 cm. in length. Except in the color of the branchlets, 
the small size of the buds, and in the small size of the fruit, this 
number resembles C. laciniosa. 
No. 253, J. Dunbar, August 31, 1915. Although only puberu- 
lous, the leaves otherwise generally resemble those of C. laciniosa. 
The fruit is similar to that of no. 73, but the involucre is 7 mm. in 
thickness; the nut is only slightly compressed and angled. The 
branchlets are reddish brown, pubescent, and as stout as those of 
the common form of C. ovata. The bud is 1 cm. long with ‘Gag 
cent outer scales. 
No. 254 Golah, J. Dusted. August 31, 1915, has leaves resem- 
bling those of no. 68, the fruit of C. Jaciniosa, and red nearly glabrous 
winter branchlets. The winter-buds are 1 cm. long with puberu- 
lous outer scales. 
No. 59, Mount Morris, Livingston County, J. Dunbar. This 
has leaves like no. 68 from Golah; the fruit is that of C. laciniosa 
and 4cm.long. The branchlets are slender, reddish, and glabrous; 
the winter-buds are about 1 cm. in length with pubescent outer 
scales. 
There is so much variation in these trees that their hybrid 
origin seems probable. The most remarkable things about them 
are the red glabrous lustrous branchlets of some of the trees; these 
are entirely unlike those of either of the supposed parents and sug- 
gest that one of the forms of C. ovalis or C. glabra might have had 
some influence on them. If they are hybrids in large part between
