Variety. 



f C. t. 2 maxima Xiitt. 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. Ilusk exceedingly 

 thick. Nut quadrangular, very large; having a thick shell, and a 

 macro that is prominent, quadrangular, and truncate at the tip, 

 {Nutt.) 



The leaves grow so rapidlj', 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 truit 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., S^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 depressedlv 

 f;lobose, 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. (Mich.v.) A large deciduous tree. New England to Carolina, and 

 throughout the Alleghany Mountains, in forests where the soil is fertile. 

 Height soft, to 90ft. Introduced in 1629. Flowers greenish; May. 

 Fruit with a greenish husk, enclosing a white nut; ripe in November. 

 The growth of the leaves is so rapid, that in a month they attain their full 

 length, which, in vigorous trees, is sometimes above 20 in. The fruit is round, 

 with four depressed seams, and averages, in general, 5h in. in circumference. 

 The husk separates entirely from the nut ; and its thickness is so dispropor- 

 tioned to the size of the nut, as to forna a character peculiar to this species 

 and C. sulcata. The ,^s, M v^ 



nuts are white fg f^Q. f\ gX

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 ant: 

 sweeter than that 

 of any other Ame- 

 rican walnut or 

 hickory, except that 

 of C. olivaeformis ; but it is inferior to the fruit of the European walnut.
