Naturalisation in Extra-Tropical Countries. 103 



Carum Roxburghianum, Bentham. 



Southern Asia, where it is extensively cultivated for curries, 

 particularly in North- Western India [Atkinson]. 



Carum segetum, Bentham. (Anethum segetum, Linn<$.) 



Around the Mediterranean Sea, extending to Western Europe* 

 An aromatic annual herb, available for culinary purposes. 



Carya alba, Nuttall.* 



The Shagbark-Hickory and Shellbark-Hickory also. Eastern 

 North-America, extending to Canada and Carolina. Professor 

 Schuebeler found it to be hardy in Norway to lat. 63 52'. Lately 

 adopted among trees from abroad for forest-culture in Prussia [C. 

 Bolle]. A deciduous tree, reaching a height of 90 feet ; it 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 and a variety of other purposes. 

 Yields the main supply of hickory-nuts. All the hickories are 

 extensively used in North- America for hoops. Circumference of stem 

 2 feet above ground 30 inches after 24 years at Nebraska [Furnas]. 



Carya amara, Nuttall. 



The Bitternut-Tree or Swamp-Hickory. Eastern North-America, 

 extending to Georgia and Texas. A tree, sometimes 80 feet high. 

 Replacing C. alba on low wet ground [B. E. Fernow]. Wood less 

 valuable than that of other hickories. Richest of all North- American 

 trees in potash, in which most hickories abound. Hardy at Chris- 

 tiana. The flowers of all the Caryas yield much honey [Dam- 

 koehler]. 



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



The Hognut-Tree. Eastern North-America, reaching Canada 

 and Florida. Often to 80 feet high ; sometimes over 100, with a 

 circumference of 15 feet at 5 feet from the ground [Prof. Meehan]. 

 Wood very tough ; the heart-wood reddish or dark-coloured ; much 

 used for axle-trees and axe-handles, and particularly for wooden 

 shoes. Rate of stem-growth in Nebraska, 38 inches circumference 

 in 24 years [Nuttall]. 



Carya microcarpa, Nuttall. 



The Balsam-Hickory. Eastern North- America. A fine lofty tree, 

 attaining a height of 80 feet, with a stem 2 feet in diameter. The 

 wood is pale and tough, and possessed of most of the good qualities 

 of C. tomentosa, to which this species is also in other respects allied. 

 Also very closely related to C. alba. The nut is of pleasant taste, 

 but small [Nuttall].
