LXVII. JUGLANDA CEE: CA‘RYA. 739 
Variety. 
¥ C. 2. 2 maxima Nutt. — Leaflets 7 in a leaf, ovate-lanceolate, acuminate, 
serrulate ; beneath, softly pubescent, and of a paler colour; terminal 
leaflet subpetiolate. Fruit partly globose, of nearly twice the size 
ordinary in the species; as large as an apple. Husk exceedingly 
thick. Nut quadrangular, very large; having a thick Shell, and a 
mucro that is prominent, quadrangular, and truncate at the tip. 
( Nuit.) 
The leaves grow so rapidly, that Michaux has seen them gain 20 in. in 
18 days. With the first frosts, they change to a beautiful yellow, and fall off 
soon after. The fruit is ripe in November, and varies very much in size and 
shape. The shell is very thick, and extremely hard; and the kernel, which is 
sweet, though small, is so difficult to extract, because of the strong partitions 
which divide it, as to have given rise to the name of mocker-nut. There are 
numerous specimens of this tree in the Bois de Boulogne, which were sown 
there by Michaux fils in 1822; and in 1840, when we saw them, were from 
20 ft. to 30 ft. high.

Spec. Char., &c. Leaflets, in a leaf, 5—7; oblong-acuminate, argutely serrate ; 
villous beneath; the pair nearest to the base of the petiole rather remote 
from it ; terminal leaflet nearly sessile. Catkin glabrous. Fruit depressedly 
globose, with 4 longitudinal furrows, in the line of which the husk divides 
into 4 valves that become wholly separate. Nut compressed, oblique, 4- 
angled in its transverse outline, white. Bark exfoliating in long narrow 
strips. (Michr.) A large deciduous tree. New England to Carolina, and 
throughout the Alleghany Mountains, in forests where the soil is fertile. 
Height 80 ft. to 90ft. Introduced in 1629. Flowers greenish; May. 
Fruit with a greenish husk, enclosing a white nut; ripe in November. 
The growth of the ieaves is so rapid, that in a month they attain their full 
length, which, in vigorous trees, is sometimes above 20in. The fruit is round, 
with four depressed seams, and averages, in general, 53in. in circumference. 
The husk separates entirely from the nut; and its thickness is so dispropor- 
tioned to the size of the nut, as to form a character peculiar to this species 
and C. sulcata. The Sy 
nuts are white f 4 
(whence the name 5 
of C. alba), com- 
pressed at the sides, 
and marked by 
four distinct angles, 
which correspond 
to the divisions of 
the husk. The ker- 
nel is fuller and 
sweeter than that 
of any other Ame- 
rican walnut or 1424. ©. alba. 
hickory, except that . 
of C. oliveformis ; but it is inferior to the fruit of the European walnut.
