TREES OF MINNESOTA. 



Salix pentandra. ( Salix laurifolia of horticulturists. ) 

 Laurel-Leaf Willow. 



Leaves larger than those of any other of our cultivated 

 willows, taper pointed, finely serrate with large stipules; 

 upper surface of leaf dark green and shin- 

 ing as if varnished. Leaves are very thick 

 and so hard that the saw-fly larvae are sel- 

 dom found feeding on it. A vigorous grow- 

 er when young, making a small, round, 

 open topped tree; valuable for variety. 

 The only objection to the extensive planting 

 of this tree here is a blight, which is occa- 

 sionally injurious to it. On this account it 

 should be used only in a small way. The 

 form planted here bears pistillate flowers. 

 Native of Europe. Propagated by cuttings. 



Salix lucida. Shining "Willow. 

 Leaves 3 to 5 inches long and 1 to 1$ 

 inches wide, lanceolate, taper-pointed, dark 

 green and glossy on the upper and paler 

 on the lower surface with broad yellow 

 midribs. Stipules i to i of an inch broad, 

 Catkins later than 

 Oc- 

 casionally a small tree but within our range a shrub. 



Distribution. Newfoundland to Hudson Bay, westward to 

 base of Rocky Mountains and south to Pennsylvania and 

 eastern Nebraska. 



Propagation. By cuttings and by seeds. 



Uses. The Shining Willow is a pretty ornamental shrub 

 on account of its lustrous green leaves and showy staminate 

 flowers. Much resembles the Laurel-Leaf Wil]ow.

Leaves lanceolate-acuminate, dark green and shining 

 above, pale glaucous below, crenate, those on strong shoots
