"Picturesque Worcester," a marvelous 1895 compilation of Worcester anecdotes and photographs, includes a section on "Great and Notable Trees" - a towering
yellow locust, monster cherry trees, and a large black walnut at the Green estate (later Green Hill Park), an enormous elm on Apricot Street, and an imposing sassafras on Elm.
Black locust, false acacia, robinia, honey locust, pea flower, post locust,
yellow locust, green locust and white locust.
Whereas most forest types are dominated by two or three species, the mixed mesophytic harbors 80 woody species including beech, yellow poplar, basswood, sugar maple, chestnut, sweet buckeye, red oak, white oak,
yellow locust, birch, black cherry, cucumber tree, white ash, red maple, sour gum, black walnut, and various hickories.
