THE MAPLE TRIBE. 



inches broad, divided to about the mid- 

 dle into 5 broad, usually obtuse lobes, 

 entire or sinuate, glabrous above, often 

 downy underneath. Flowers few, on 

 slender pedicels, in loose, erect corymbs, 

 shorter than the leaves. Carpels downy 

 or rarely glabrous, the wings spreading 

 horizontally, so as to form together one 

 straight line. 



In European woods, extending east- 

 ward to the Caucasus, and northward to 

 southern Sweden. In Britain, abundant 

 in southern England, and apparently 

 truly indigenous as far north as Cheshire 

 and the Tyne. Scarcely indigenous in 

 Ireland. Fl. spring.

Sycamore Maple. Acer Pseudo-platanus, Linn. 

 (Eg. 219.) 

 (Eng. Bot. t. 303. Sycamore.) 



A much handsomer and freer-growing 

 tree than the common M., the leaves 

 larger, with more pointed and toothed 

 lobes, not unlike those of a Plane-tree. 

 Flowers in loose, oblong, hanging ra- 

 cemes. Wings of the carpels nearly 

 parallel, or diverging so as to form a 

 right angle, not spreading into one 

 straight line. 



A native of the mountains of central 

 Europe and western Asia, extensively 

 planted in Britain, and in many places 

 sows itself so readily that it may al- 

 most be considered as naturalized. Fl. 

 spring.
