The American Plane Tree, or Buttonwood (A. occidentalis), was formerly considered one of the most important shade trees; but the mysterious disease, which has prevailed throughout the country for a number of past years, has so disfigured them that they are not desirable at the present time. No cause or remedy for the disease has yet been discovered, but it is said to be passing away, or, in some places, nearly gone, so that it is hoped this majestic tree will resume its importance in the public square, or by the roadside.
P. orientalis, or the Oriental Plane, is a tree of smaller growth than the American species. Its general height is about fifty feet.
'It has beautiful foliage, and well deserves a place among other trees.
