3. Amenta coaetaneous, long and loose, at the summit of short lateral leafy branches ; 



ovaries smooth; scales greenish-yellow, deciduous ; branches brittle at base. 



(Ovary sessile. 



7. S. dlba, L. Leaves elliptic-lanceolate, acuminate, denticulate^

 WHITE SALIX. White Willow. [See S. vitellina, L. Fl. Cestr. ed. 

 2. p. 562.] 



Stem 30 to 50 or 60 feet high, much branched; branches rather erect, with a pale 

 greenish-yellow bark. Leaves 2 to 3 or 4 inches long, the lower teeth glandular; 

 petioles 1 to 2 lines in length. Pistillate aments 2 to near 3 inches long, greenish.

Obs. The white 'willow, if I mistake not, is the one which is pre- 

 ferred, and cultivated, by the manufacturers of Gun-powder, for 

 the purpose of making charcoal. It was introduced as a shade-tree, 

 about our old settlements; but is now generally superseded by the 

 Weeping Willow. It is, however, partially naturalized in some 

 localities. The S. vitellina, L. with more spreading orange-yellow 

 branches, and rather shorter and broader leaves (which Mr. CAREY 

 reduces to a var. of this) is also occasionally seen, as a shade- 

 tree, and partially naturalized. I think we have none but the pis- 

 tillate plants, of both varieties. The twigs of the var. vitellina, or 

 golden Osier, are much used, in Europe, for making baskets. In 

 WATSON'S Annals of Philadelphia, we are told that the Yellow Wil- 

 low, in this State, came originally from some wicker-work found 

 sprouting, in Dock Creek. It was seen by Dr. FRANKLIN, who 

 took it out and gave the cuttings to CHARLES NORRIS ; who reared 

 them on the grounds now the site of the Custom House, or late 

 Bank of the U. States. 



f f Ovary pedicellate. 



8. S. frdgilis, var. Russelliana, Carey, in Gr. Man. Leaves lanceo- 

 late, acuminate, serrate-dentate with the teeth incurved, subglaucous 

 beneath, and slightly silky while young ; stipules semi-cordate ; 

 styles conspicuous.

 BRITTLE SALIX. Bedford Willow. 



Stem 30 to 50 feet high ; brandies rather erect, with a greenish-brown smooth 

 bark, somewhat pubescent when young, remarkably brittle at base. Leaves 2 to 

 4 inches long, acute at each end, finally smooth ; petioles 2 lines to % an inch in 

 length, glandular and somewhat pubescent. Pistillate. aments 2 to 2% inches lo ng; 

 capsules tawny-green. 

 Hob. Low grounds. Nat. of England. Fl. May. Fr. 



Obs. This species is abundant on the Brandywine, about Wistar's 

 Bridge ; and has been advantageously propagated, inr that vicinity, 

 in localities where few other trees would grow. I have seen none 

 but pistillate plants. 



5). S. niarra, Marshall. Leaves narrow-lanceolate, 'tapering and 

 acute at each end, smooth and green on both sides, with the petiole 

 and midrib pubescent; stipules small, caducous; stamens 3 or 4 

 to 6 ; styles short.
