Vattety. 



If C. t. 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. 

 (Nutt.) 



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 

 20ft. to 30ft. high.

Spec. Char.y $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. (Michx.) A large deciduous tree. New England to Carolina, and 

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

 Height 80ft. 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, 5^ 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 form a character peculiar to this species 



and C. sulcata. The 



nuts are white 



(whence the name 



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 



hickory, except that 



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