The fruit is usually short stalked, fre- quently two from the same Bur Oak, Ovi-rcuii 0:ik—(Qwfivus macrocaipa, Miclix.) The Bur Oak, or Ovcrcup Oak, is mainly a native of the Mississippi valley, extending spar- ingly into some of the Eastern States. It is a large tree, of irregular shape, with long angular limbs, and bark rather rougher and darker than the White Oak. It is the principal tree of the oak openings of the Western States, in which situations the wood is coarse grained and brittle; but when growing in a dense forest the tree is more regular in shape, and the timber of a bet- ter quality. The leaves are obovate in outline, broad at the top, and narrow at the base, with three to tive lobes on each side, the lower ones small, and the divisions reaching nearly to the midrib, the upper ones longer and broader. The under surface is white with a fine down, the upper surface glossy green. They are nar- row, wedge-shaped at the base, and with stalks an inch or more in length. The acorn is round- ish, about an inch long, and usually nearly enclosed by the cup, which is deep, and exter- nally rough, with pointed scales, at the edge becoming long and loose to form a mossy fringe to the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Metcalf Collection (North Carolina State University).
