182 JUGLANDACE^. Carya. 



nearly half an inch thick. Nut about an inch long, whitish, compressed and angular, the 

 breadth often equal to the length : shell thin and fragile. 



Rich moist woods ; common. Fl. May. Fr. October. The nuts of this species are 

 more esteemed than those of the other hickories, except the C. sulcata. The wood is very 

 strong and elastic ; and being easily split, is often used for making baskets. It composes a 

 large portion of the hickory sold for fuel in New- York and other large towns. 



2. Carya tomentosa, Nutt. White-heart Hickory. Mocker-nut. 



Leaflets mostly 7, oblong- and obovate -lanceolate, acuminate, slightly serrate, roughly 

 pubescent underneath ; sterile aments hairy ; drupes globose-ovoid or oblong ; nut somewhat 

 6-angled , the shell thick and very hard. — Nutt. gen. 2. p. 220 ; Beck, hot. p. 336 ; Dar-

var. integrifolia (Plate C.) : leaflets 3-4 pairs, nearly entire ; fruit small. 



A tall tree ; the trunk being often 50 to 80 feet high, and the diameter 12 - 18 inches. 

 Bark rough and cracked, but not scaly. Leaflets 2-6 inches long ; the lower pairs smaller 

 than the others ; terminal one cuneate at the base, and stalked : petiole and under surface of 

 the leaves clothed with a roughish stellate pubescence. Sterile aments long and pendulous, 

 with a pair of connate bracts at the base. Middle lobe of the calyx-scales longer and acute ; 

 lateral ones obtuse, and sometimes toothed. Anthers 3-4. Pistillate flowers 2 — 3 together. 

 Limb of the calyx 4-cIeft ; the lobes lanceolate, conspicuous. Drupes 1^-2 inches or more 

 in length (in the variety much smaller), roundish or a little oblong ; the valves scarcely more 

 than half as thick as in the preceding species. Nut light brown ; the kernel good, but small. 



Fertile moist woods ; frequent. Fl. May. Fr. October. The wood of this species is the 

 best of all the hickories for fuel. It is white throughout, until it becomes 6-8 inches in 

 diameter. In consequence of the abundance of its sweet sap, it is liable to the depredations 

 of insects, particularly the larvae of Callidium flexuosum. ( See a figure of the insect in 

 Michaux's plate, I. c.) 



3. Carya glabra. (Plate CL) Pig-nut. Broom Hickory. 



Leaflets about 7, lanceolate, acuminate, acute at the base, smooth on both sides ; drupes 

 pyriform or nearly globose, the valves thin ; nut compressed, hard. — Juglans glabra, Muhl.

Trunk 40 - 100 feet high and 12 - 18 inches in diameter (much larger in the Southern and 

 Western Slates), with an even bark. Leaflets mostly 7, but sometimes 9 or only 5, 2 - 5 

 inches long, with a long acumination, serrate ; the under surface sometimes a little pubescent,
