J uglandacecc Jiiglans. 407 



are from North America and the mountains of Asia. The name 

 is a corruption of Jovis glans, literally Jupiter's Nut. 



1. J. regla. Common Walnut. This handsome and useful 

 tree needs no description ; but we may call attention to some 

 of the better varieties. Those most valued for their nuts are 

 the Highflyer, Titmouse, or tenera (thin-shelled), and serotina, 

 the latter being valuable on account of its flowering season 

 being a month later than the ordinary form, and thus escaping 

 the Spring frosts. There is also a very large-fruited variety 

 called the Double Walnut, whose shells are often polished and 

 hinged, and filled with trinkets. The varieties most esteemed 

 for their foliage besides the ordinary one are lacinicita, hetero- 

 phylla, variegata, monophylla, and aypleniifolia. The names 

 are sufficiently descriptive of the peculiarities of the several 

 varieties. Native of Asia, from the Caucasus 1.o China. 



J. nlgra. Black Walnut, is an erect tall-growing tree, 

 with more numerous toothed leaflets hairy beneath, and a more 

 persistent husk. Nut spherical, corrugated, edible, but not 

 equal to the common Walnut. It is a native of the Western 

 States of North America. There are some varieties of this, 

 and one called intermedia, supposed to be a hybrid between 

 this and the foregoing. J. cinerea, Butternut, is also a North 

 American species. It has greyish bark, glutinous branches, 

 and oblong fruits with only one partition at the base. 



2. CARYA. 



This differs from the last genus in having the male catkins 

 usually in threes, each flower with 8 or fewer stamens, and the 

 epicarp or husk splits into 4 regular valves, with a smooth "en- 

 docarp or shell. The species are all North American. Kapva 

 is an ancient name of the Walnut. These handsome trees are 

 almost unknown in England, and rarely quoted in our nursery 

 catalogues, probably on account of their not being very hardy. 



G. olivceformis, Pecan-nut, is an elegant slender tree, 

 and the only species bearing really palatable nuts, which are 

 imported in small quantities. They are smooth, 4-ribbed and 

 olive-shaped. C. alba is the Shell-bark Hickory, valuable for 

 its timber and Hickory nuts. G. glabra, syn. porclna, is the 

 Pig-nut or Broom Hickory. C. amara is called Bitter Nut 

 or Swamp Hickory, and C. tomentosa is the Mocker Nut or 

 White-heart Hickory. The tough young wood and the highly 

 coloured older timber of some of the species is in great request.
