valued in N.W. America for furniture and indoor work more so than that of 

 any other tree of those regions except conifers. It would seem to be worth

ACER MACROPHYLLDM. 



A. MANDSHURICUM, Maximowicz. MAKCHURIAN MAPLE. 



A small, deciduous tree, sometimes a shrub. Leaves composed of three 

 leaflets, on a stalk up to 4 ins. long. Terminal leaflet 2 to 3^ ins. long, i to 

 ij ins. wide, lanceolate, pointed, saw-toothed, smooth when mature except for 

 hairs along the midrib ; the side leaflets are rather smaller and shorter-stalked 

 than the terminal one ; main leaf-stalk often longer than the largest leaflet. 

 Flowers greenish yellow, often produced in threes ; stamens not protruding. 

 Fruit smooth, purplish when young ; keys ij to i^ ins. long ; wings ^ in. wide, 

 the pair forming an angle of about 90. 



Native of E. Siberia and Manchuria ; small trees in cultivation at Kew 

 were received from St Petersburg in 1904. This maple is closely allied to 

 A. nikoense and A. sutchuenense ; the former differs in its hairy young leaves 

 and flower-stalks, the latter in its many-flowered inflorescence and protruding 

 stamens. It is very liable to injury by late spring frost.
