Order XXXIII
ACERINEÆ.
Valuable trees, native of the woods of Europe, Siberia, and North America. Their flowers are in all cases inconspicuous; the breadth and rich color of their leaves constituting their beauty. All the larger species abound in a very saccharine sap, from which sugar is prepared in North America; it is chiefly made from A'cer saccharínum and Negúndium, but may be obtained from many others. 2143 A'cer W. 2144 Negúndium Dec.
