QUERCUS PALUSTRIS, DU ROL 91 



Fruit. Maturing the second year; nearly sessile or on 

 short footstalks : cup top-shaped to hemispherical ; scales 

 less firm than in Q. coccinea, tips papery and transversely 

 rugulose, obtuse or rounded, or some of them acutish, often 

 lacerate-edged, loose towards the thick and open edge of the 

 cup : acorn small : kernel yellow within and bitter. 



Horticultural Value. Hardy throughout New England ; 

 grows in well-drained soils, but prefers a rich, moist loam ; of 

 vigorous and rapid growth when young, but as it soon begins 

 to show dead branches and becomes unsightly, it is not a 

 desirable tree to plant, and is rarely offered by nurserymen. 

 Propagated from seed. 



Note. Apparently runs into Q. coccinea, from which it 

 may be distinguished by its rougher and darker trunk, the 

 yellow color and bitter taste of the inner bark, its somewhat 

 larger and more pointed buds, the greater pubescence of its 

 inflorescence, young shoots and leaves, the longer continuance 

 of scurf or pubescence upon the leaves, the yellow or dull red 

 shades of the autumn foliage, and by the yellow color and 

 bitter taste of the nut.
