ACER (from acer, hard or sharp; wood is extremely 

 hard, and was formerly much used for making pikes and 

 lances). Maple. OED. Sapindaeece. A. genus comprised, 

 for the most part, of handsome hardy deciduous 

 shrubs, or trees, adapted for forming shrubberies, 

 plantations, <tc. Flowers greenish, except where men- 

 tioned. A. Pseudo-platanu* is one of our most useful 

 forest trees. Several of the species produce very useful 

 timber ; sugar is one of the constituent parts of the sap of 

 all of them, and is obtained in large quantities from A. 

 taccharinum. in North America. They all prefer a some- 

 what sheltered position. The most satisfactory soil is 

 one free, deep, loamy, and well drained ; the latter is 

 especially desirable with some of the Japanese varieties. 

 The varieties of A. japonicum. and palmatum are well 

 worth growing in pots for conservatory decoration. Pro- 

 pagation: By seeds, sown either in autumn or spring, 

 covering them not more than a iin. deep ; the common 

 varieties may be sown outside, while the rarer ones should 

 be sown in a frame. By layers, and by grafting; the 

 latter method is adopted with many of the rarer species
