562 DIOECIA TETRANDRIA 



1 h:ivc not yet mot with any but the pistillate plant. The prevailing dark crtrn 

 hue of this species, and my limited acquaintance with the genus, when my Caul" 

 oguo was published, led me to insert it in that work by the erroneous name of S 

 ta'zra. Dr. Beck cites it as a Synonym of his S. dtcipiens ; but in this I thiuk 

 there must be a mistake. 



10. N. vithllixa, L. Leaves lanceoluto, acute, glandular-serrulate, 

 or nearly entire, smoothish above, silky beneath ; amenta coaHuneous ; 

 ovaries ovoid-lanceolate, smooth, subsessile; style short. Beck, Hot.

Stem 20 to 30 or 10 feet high, and 1 to 2 feel in diameter, wilh numerous rathe r 

 erect branches, and a smooth shining orange-yellow (or sometimes pale greenish • 

 yellow) bark. Leaves 2 to 3 inches long, and half an inch to 3 quarters wider 

 generally lanceolate, acute, and wilh indistinct cartilaginous glandular serraturcs, 

 —not unfrequcntly obovale-oblong, obtuse, and entire (especially when young, or 

 the early ones it the base of the young branches),— silky pubescent, finally smooth 

 and yellowish-green above, silky and glaucous beneath ; jKlioles 1 to 2 lines long, 

 pubescent ; stipules minute, lance-ovate, caducous (none, Pursh, Berk, &.«.). 

 Pistillate anient s 2 to 2 and a half inches long ; scales ovate-lanceolate, externally 

 pubescent, and piloso-Cillatc ; ovaries ovoid lancev late, smooth, on very bhori 

 pedicels ; rw his pubescent. 

 Hub. About houses; meadows, and low grounds: frequent. Fl. April. Fr. June- 



Obs. This was early introduced, here, as a shade tree; and has Income parti- 

 ally ualuralized, in many places. I think I have never seen any but the pisti'latt 

 plant. A variety, with paler bark (perhaps the S. alba, of Authors) is also occa- 

 shnally to be met with. The handsome S. babylonica, or Weeping Willow, is 

 more generally preferred as an ornamental Shade tree,— and the pistillate plant 

 of that species is extensively propagated about houses; but it can hardly be paid 

 ;.» be naturalized. Some 20, or more, additional species of this large and very 

 difficult genus, have been enumerated in the U. States.
