Note: The Oriental plane ({Platanus orientalis}) is a native
of Asia. It rises with a straight, smooth, branching
stem to a great height, with palmated leaves, and long
pendulous peduncles, sustaining several heads of small
close-sitting flowers. The seeds are downy, and
collected into round, rough, hard balls. The Occidental
plane ({Platanus occidentalis}), which grows to a great
height, is a native of North America, where it is
popularly called {sycamore}, {buttonwood}, and
{buttonball}, names also applied to the California
species ({Platanus racemosa}).
