SYCAMORE MAPLE 



Acer Pseudo-Platanus L. 



HABIT A rather large tree of vigorous growth, reaching in Europe 

 120 ft. in height, with large spreading head. 



BARK Dark reddish-brown, flaking off in squarish or short oblong 

 scales. 



TWIGS Stout, smooth, shining, yellowish-greenish to brown. 



LEAF-SCARS Opposite, shallow, V-shaped; adjacent edges of opposite 

 leaf-scars not meeting. BUNDLE-SCARS 3 elongated lengthwise with 

 the leaf-scar or compound. 



BUDS Green, sometimes slightly reddish, terminal bud larger than 

 lateral buds, 7-12 mm. long, broadly oval to ovate to nearly spherical, 

 much more than *& as wide as long; lateral buds divergent. BUD- 

 SCALES more or less keeled, with dark brown edging, dark pointed 

 apex and finely hairy margin; scales to terminal bud, 6-7 pairs, 3 pairs 

 at least generally visible, the outer scales smooth, the 2 inner scales 

 thickly covered with silvery white hairs.

 spherical, wings making about a right angle resembling fruit of the

 buds, having outer scales with dark margins and white-hairy inner 

 scales and by the flaky bark; from the native Maples by the larger 

 buds and the peculiar bark.

 as a shade tree but less extensively than the Norway Maple.
