Carum segetum, Bentham. (Anethum segetum, Linne) 



Around the Mediterranean Sea, extending to Middle Europe. An- 

 aromatic annual herb, available for culinary purposes. 



Carya alba, Nuttall.* 



The Shellbark-Hickory. North America, extending to Canada. 

 A deciduous tree, 90 feet high, which delights in rich forest-soil. 

 Wood heavy, strong, elastic and tenacious, but not very durable ; 

 used for chairs, agricultural implements, carriages, baskets (Sargent), 

 whip-handles. Yields the main supply of hickory-nuts. All the 

 hickories are extensively used in North America for hoops. 



Carya amara, Nuttall. 



The Bitternut-Tree or Swamp-Hickory. A tree, 80 feet high, in 

 swampy grounds of North America. Wood less valuable than that 

 of other hickories. Richest of all North American trees in potash, 

 along with most hickories. 



Carya glabra, Torrey.* (Carya porcina, Nuttall). 



The Hognut-Tree. North America, reaching Canada and Florida. 

 80 feet high. Wood very tough ; the heart wood jreddish or dark-

The Balsam-Hickory. North America. ;/ A fine lofty tree attaining 

 a height of 80 feet, and a stem of 2 f eeiain diameter. The- wpod is 

 white and tough, and possessed of most of the good qualities,:, of C. 

 tomentosa, to which this species is also '.in .other respects/ allied. 

 The nut is of a pleasant taste, but small (Kuttall). Ver^" closely 

 allied to C. alba * 



Carya oliviferous, Nuttall.* 



The Pecannut-Tree of North America. A handsome lofty tree 

 up to 70 feet high, with a straight trunk. The most rapid-growing 

 of all the hickories (Meehan). Its wood is coarse-grained, heavy 

 and compact, possessing great strength and durability ; in strength 

 and elasticity it surpasses even that of the White Ash (Harrison), 

 and is quite as durable. The nuts, which are usually abundant, 

 are from an inch to an inch and a half long, and are the most 

 delicious of all walnuts ; they form an object of commerce in the 

 Southern States. The tree bears nuts as far north as Philadelphia. 

 It commences to bear nuts in about eight years ; they should be 

 packed in dry moss or sand for distant transmission. Although the 

 wood of all the hickories is not adapted for building purposes, as it 

 is easily attached by insets and soon decays if exposed to the 

 weather, yet its great strength and elasticity render it extremely
