32 TREES OF NEW ENGLAND. 



elongating ; bracts cut into several lanceolate divisions, silky- 

 hairy ; stamens about 10; anthers red: ovaries short-stalked ; 

 stigmas two, 2-lobed, red. 



Fruit. Fruiting catkins at length 3-6 inches long : capsule 

 conical, acute, roughish-scurfy, hairy at tip : seeds numerous, 

 hairy. 



Horticultural Value. Hardy throughout New England ; 

 grows almost anywhere, but prefers moist, rich loam ; grows 

 rapidly and is safely transplanted, but is unsymmetrical, easily 

 broken by the wind, and short-lived; seldom offered by nursery- 

 men, but readily procured from northern collectors of native 

 plants. Useful to grow for temporary effect with permanent 

 trees, as it will fail by the time the desirable kinds are well 

 established. Propagated from seed or cuttings. 



Note. Points of difference between P. tremuloides and 

 P. grandidentata. These trees may be best distinguished in 

 early spring by the color of the unfolding leaves. In the 

 sunlight the head of P. tremuloides appears yellowish-green, 

 while that of P. grandidentata is conspicuously cotton white. 

 The leaves of P. grandidentata are larger and more coarsely 

 toothed, and the main branches go off usually at a broader 

 angle. The buds of P. grandidentata are mostly divergent, 

 dusty-looking, dull ; of P. tremuloides^ mostly appressed, 

 highly polished with a resinous lustre.
