42 MISSOURI BOTANICAL GARDEN. 
exceptionally slightly tomentose, with numerous elongated 
white lenticels; buds somewhat smaller and with the nearly 
glabrous outer scales commonly longer pointed; fruit sub- 
globose, about an inch and a half long; husk 5 to 8 mm. 
thick, glabrous; nut nearly one-half smaller than in the 
last, typically scarcely longer than broad, nearly white; 
shell 1 mm., the firm commissure very thin; kernel very 
sweet.— Canada to Minnesota, south to Florida, Kansas, 
and Texas,— in river bottoms and uplands.— Pl. 12, 15, 
f. 6-9, 19, f. 6-7. 
Like the Pecan, the Shagbark has given rise to several 
superior races, some of which are cultivated. 
JUGLANS, L. 
Pith chambered, with persistent thin diaphragms; buds 
frequently superposed, the terminal subnaked, their leaves 
valvately arranged; vernation of leaflets conduplicate 
(pl. 25, f. 1), catkins mostly elongating somewhat in early 
winter; fruit with indehiscent persistent husk. 
* Leaf scars little notched at top, surmounted by a yellow-velvety 
transverse prominence. 
1. J. cinerea, L. — The Butternut. — A medium-sized 
tree; bark gray, rather smooth between the deep fissures ; 
twigs reddish-buff, with staring hairs or soon nearly glab- 
rous, with numerous small white lenticels; pith dark 
brown, with narrow chambers little wider than the interven- 
ing diaphragms; terminal buds longer than broad, densely 
yellow-pubescent, the outer scales lobed at apex; fruit 
elongated, the husk villous, the nut 2-celled at base.— New — 
Brunswick to Dakota, Kansas, and the mountains of 
Georgia and Alabama.— PI. 24, f. 1-4. 
Three Asiatic species, related by their buds and leaf scars 
to the Butternut, are more or less cultivated in the United 
States: — J. Sieboldiana (pl. 25, f. 3), with pale closely 
set pith plates, puberulent brown twigs with conspicuous
