SYCAMORE OAK TREES ALTERNATE SIMPLE LEAVES OAKS & SYCAMORE: Every leaf lobed or coarsely round- toothed; 3-5 MAIN VEINS NOT MEETING AT LEAF BASE; THORNLESS SYCAMORE Platanus occidentalis Bark on upper trunk and branches very characteristic: thin brown flakes coming off in jigsaw-puzzle-like pieces exposing whitish underbark. Ball-like heads of fruit mostly single on long stalks (introduced species with more than one per stalk). Low woods, near streams. Occasionally planted. Uncommon. SWAMP WHITE OAK Quercus bicolor Leaves mostly with ten or fewer pairs of shallow lobes (side veins) usually rounded, usually white-downy beneath. Acorns on long stalks ( cm.), some- times sweetish, edible if properly prepared. Bark flaky or ridged, some- times deeply so. Mostly bottomlands, margins of streams, swamps. Common. CHESTNUT OAK Quercus prinus Leaves mostly with 10-16 pairs of rounded teeth" (side veins), often slightly white-hairy beneath. Acorns on stalks shorter than leafstalk, or stalkless, sometimes sweetish, edible if properly prepared. Trunk bark deeply furrowed. Dry, often rocky woods. Uncommon. WHITE OAK Quercus alba Leaves with rounded, distinct lobes, hairless when mature. Acorns on short stalks or stalkless, sometimes sweet, edible if properly prepared. Bark usually pale and flaky. Dry woods, roadsides, pastures. Common. ENGLISH OAK Quercus robur Leaves similar to White Oak but lobed at base rather than tapered. Acorns on long stalks. Mature bark deeply furrowed. Infrequently planted; occasionally SWAMP WHITE OAK.
