ARBORETUM ET FRUTICETUM BRI'J'ANNICUM. 



Champlain, in Pennsylvania, and high mountains in Carolina and 

 Georgia. 

 ^ Q. t. 2 sinubsa Michx. Quer, t. 25. Leaves deeply sinuated. Cnp flat 

 and turbinated. Nut ovate. Native of South Carolina and Georgia. 



The trunk is straight, and is covered with a deeply furrowed bark of mid- 

 dling thickness, but always black, or of a very deep brown colour ; whence 

 probably the tree derives its common name in America, viz. the black oak. 

 The dark hue of the bark easily distinguishes this tree from Q,. rubra, Q. coc- 

 clnea, and Q,. ambigua, in the northern provinces ; but, in the southern ones. 



1SS8. Q. tincMria. 



Q. falcata having bark of the same colour, Q. tinctoria can only be dis- 

 tinguished by its buds, which are longer, more acuminate, and more scaly, 

 than those of the former species. The inner bark of Q. tinctoria, if chewed, 

 is very bitter, and gives a yellow tinge to the saliva, which is not the case with 

 the bark of Q. falcata. The woolI is reddish, coarse-grained, and porous, 

 like that of all the red oaks. The leaves are large, deeply laciniatecl, and 

 resemble those of Q. coccinea, but they have fewer lobes, never exceeding 

 four or five ; while the leaves of the old trees of Q. coccinea have from five 

 to seven : they are also less openly and roundly sinuated, less shining, and of a 

 duller green ; and, during a part of the summer, have their surfaces roughened 

 with small glands, which are visible to the eye and sensible to the touch, and 

 which are also found on the young shoots. In autumn, the leaves of young 

 trees turn to a dull red ; but those on old trees become yellow, or of a yel- 

 lowish brown, beginning with the petiole. The wood is used as a substitute 

 for the white oak, and the bark ibr tanning, and for dyeing leather a brilliant 

 yellow.

Spec. Char., Sfc. Leaves smooth, oblong, deeply 

 and widely sinuated, on long stalks ; IoIjcs dis- 

 tant, parallel, acute, sharply toothed, bristle- 

 pointed; forks of the veins densely woolly be- 

 neath. Calyx of the fruit flattened. Nut nearly 

 globose. (JVilld.) A large deciduous tree. 

 Northern States of North America. Height 

 80 ft. Introduced in 1800. 



The tree, when young, assumes an agreeable 

 pyramidal shape; and its far-extending drooping 

 branches, and light and elegant foliage, render it, 

 in our opinion, the most graceful of all oaks. The 

 bark on the oldest trees of Q. paliistris is scarcely 

 ever cracked : on young trees it is perfectly smooth.
