Fuglandacce—F uglans. 407 
are from North America and the mountains of Asia. The name 
is a corruption of Jovis glans, literally Jupiter’s Nut. 
1. J. regia. 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 ¢énera (thin-shelled), und serdtina, 
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 tilled with trinkets. The varieties most esteemed 
for their foliage besides the ordinary one are lacinidta, hetero- 
phyla, variegata, monophylla, and aspleniifolia. The names 
are sufficiently descriptive of the peculiarities of the several 
varieties. Native of Asia, from the Caucasus to China. 
J. nigra, 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 isa native of the Western 
States of North America. There are some varieties of this, 
and one called intermédia, supposed to be a hybrid between 
this and the foregoing. J. cinérea, 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. 
C. oliveférmis, 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. (©. alba is the Shell-bark Hickory, valuable for 
its timber and Hickory nuts. ©. glabiu, syn. porcina, is the 
Pig-nut or Broom Hickory. C. amdrw is ‘called Bitter Nut 
or Swamp Hickory, and C. tomentésa is the Mocker Nut or 
White-heart Hickory. The tough young wood and the highly 
colcured older timber of some of the species is in great request.
