14-48 ARBORETUM AND FftUTICETUM. PART III. 



nearly twice as large as that of the species ; and having a white shell, with 

 rounded prominences instead of angles. A century of cultivation, he says, 

 would perhaps not advance the species generally to an equal degree of perfec- 

 tion with this accidental variety. Fig. 1270. represents the Sphior juglandis, 

 or Hickory Hawk Moth, which in Georgia is found on this tree. The cater- 

 pillar is smaller than that of most of the other species, and generally is of a 

 shaded red and yellow, though it is sometimes green. The perfect insects are 

 brown, and resemble the English poplar hawk moth. The caterpillar buries 

 in the ground, and varies very much as to the time in continues there : one 

 observed by Abbott having gone into the ground in May, and reappeared in 

 June ; and another having buried itself in September, and remained in the 

 ground till the following April. (Abbott and Smith, Insects of Georgia.)

Spec. Char.y Sfc. Leaflets, in a leaf, 7 9 ; obovate-acuminate, argutely 

 serrate; downy beneath. Fruit roundish, having 4 longitudinal ridges that 

 extend from the tip to the middle, and 4 intervening depressions, or furrows. 

 Husk dividing, from one extremity to the other, in the line of the furrows, 

 into 4 equal valves. Nut subglobose, slightly compressed, having a long 

 mucro at the tip, and a shorter stouter one at the base ; yellowish. Bark 

 exfoliating in long narrow strips. (MicJuc. N. A. S., Pursh FL A. S.) A 

 native of North America, in fertile valleys in the Alleghany Mountains ; and 

 flowering in April and May. Introduced in 1804. 



Description. Michaux says, speaking generally of the scaly-bark hick- 

 ories, that " they exhibit many striking traits of resemblance which may 

 warrant the grouping of them into a separate section. Besides their 

 generic and specific characters, they possess others peculiar to themselves, 

 by which they are so nearly related, that, were it not for some remarkable 

 differences, they might be treated as a single species." C. sulcata grows to 

 the height of 80 ft., with an ample head, and a straight trunk. The bark is 

 divided into strips, or shreds, from 1ft. to 3ft. long, the pieces of which, 

 when they are ready to scale off, are warped outwards at each end, and attached 

 only in the middle. When they fall, they are succeeded by others similarly 

 exposed. In this species, Michaux observes, the plates of bark are narrower, 

 more numerous, and of a lighter colour, than those of C. alba ; from which 

 differences he thought it advisable to give it the specific name of laciuiosa. 

 The leaves vary in length from Sin. to 20 in., and are composed of from 7 to 

 9 leaflets ; whereas in C. alba, the shell-bark hickory, the leaflets are invari- 

 ably 5. The barren catkins are long, glabrous, filiform, and pendulous ; 3 

 being united on a common petiole, attached to the basis of the young shoots. 

 The fertile flowers appear, not very conspicuously, at the extremity of the 

 shoots of the same spring. They are succeeded by a large oval fruit, more 

 than 2 in. long, and 4 in. or 5 in. in circumference. It has four depressed
