1918] SARGENT—CARYA 235 
Sargent, Trees and Shrubs 2:207. 1913. More distinct is a form 
with oblong fruit and pointed nuts which may be described as 
CaRYA OVATA var. ellipsoidalis, n. var.—Differing from the type 
in its ellipsoidal fruit and slender branchlets. Fruit bluntly pointed 
at the ends, much compressed, slightly angled by winged su- 
tures, rough, 3-3.5 cm. long, about 2.5 cm. wide, and 2 cm. thick; 
involucre opening to the base, 4-5 mm. thick. Nut ovoid to ellip- 
soidal, abruptly narrowed at apex into a long acuminate point, 
rounded at base, more or less compressed and prominently ridged. 
Missouri, near Hannibal, Marion County, J. Davis, September 5, 1913 
(no. 2071, type), Oakwood, Rolles County, J. Davis, September 13, 1913 
(no. 2132). These trees have unusually slender glabrous reddish branchlets 
for C. ovata, but the foliage is of that species, and the white strongly angled 
nuts, in spite of their abruptly pointed apex, are clearly the nuts of C. ovata. 
To this variety may be referred a tree found by James McHugh at Indian 
River, Lewis County, New York, September 15, 1911 (no. 11), which differs 
from the Missouri trees only in its less compressed fruit with an involucre 
5-6 mm. in thickness. Nuts of this species more or less pointed at apex 
are not uncommon, especially at the north, but I have not seen the ellipsoidal 
compressed fruit with its comparatively thin involucre of this variety except 
on the specimens from northeastern Missouri and Indian River, New York. 
CARYA OVATA var. complanata, n. var.—Differing from the type 
in its broadly obovoid, much compressed, slightly angled nuts cune- 
ate at base, and rounded truncate or slightly obcordate at apex, and 
in the oblong-obovoid fruit. Fruit 3 cm. long and about 2.5 cm. 
wide, with an involucre 5-6 mm. in thickness. Nut 2.2-2.5 cm. 
in length, 2-2.5 cm. in width, and 1.2-1.4 cm. in thickness, with 
a shell only 1 mm. thick. 
A single tree believed to be 50 years old on the Drushel Farm 2 miles 
southeast of Mt. Hope in Holmes County, Ohio. For C. ovata this tree has 
unusually slender, sparingly villose branchlets and comparatively small villose 
buds. The leaves are those of the common form of the species. For the speci- 
mens of this tree I am indebted to Professor J. ANDREW DRUSHEL, instructor 
in nature study and geology in the Harris Teachers’ College at St. Louis. In 
the shape of the nuts this is the most unusual form of C. ovata which I have 
seen, and nuts with such a thin shell are not often found in this species.

leaflets and the rather thinner involucre of the fruit, was based on
